INTRODUCTION

Welcome to the world of GPS flying! Your Bendix/King KLX 135 GPS/COMM is sure to make your flying more efficient and more fun. After all, isn't that why you got into flying in the first place? Now when you're flying VFR, you probably won't need to be constantly figuring or looking up VOR radials and distances.
The convenient QuickTune™ feature will allow you to easily look up the frequency for the appropriate airport, then transfer it to the KLX 135 COMM transceiver.
This Pilot's Guide should be of great help to you. It is written in plain, simple English and it assumes you are not an experienced user of GPS or other type of long range navigation equipment. If you are experienced, so much the better. This Pilot's Guide also includes hundreds of sample screen figures and other illustrations to make your learning easier. It is designed so that you can start at the front and progress in the order presented; however, you may want to skip around and learn things in your own order. Also, on page iv, there is an index of frequently used procedures which will help you find the page that describes how to do exactly what you want to do. There are also several appendices in the back of the manual that you may find useful from time to time.
Be sure to keep this Pilot's Guide handy with you in the airplane. It is designed to fit easily in the glove box, or in the seat pocket. The KLX 135 is very simple to operate, but the Pilot's Guide can sure be of help to you.
One last thing. Don't get so involved in learning to use the KLX 135 that you forget to fly the airplane. Be careful, and remember to keep a close eye out for other aircraft.
NOTE: A “whiskers” border is used around data on some of the figures in this Pilot's Guide to indicate that the data inside the border is flashing.

Introduction

KLX 135 SNEAK PREVIEW

If you absolutely can't wait to use your KLX 135 until you've read this Pilot's Guide, this section is for you. This page will teach you just enough to get going and then learn by doing. This operational pre­view assumes the KLX 135 has been properly installed, the unit was previously operational in the same general geographical location, and that no peripheral equipment interfaced with the KLX 135 (such as external HSIs, CDIs, autopilots, moving map display, etc.) is to be used at this time. If you are using this operational preview in flight, do so only in good VFR conditions and only with an alternate means of navigation (including pilotage) available to cross-check position.
1. Turn the unit on with the On/Off/Volume knob (the small knob in upper left hand corner). Adjust the COMM audio volume as desired by pulling this knob out, turning it to an appropriate level and pushing it back in.
2. For a few seconds, the Turn On Page is displayed while the unit runs a self-test. Afterwards, the Self-test Page is displayed. If the KLX 135 is receiving an altitude from an encoding altimeter, the present pressure altitude will be displayed on line 3. The bot­tom line should display Self-test Pass and a flashing Ok?. Press the F button to approve the Self-test Page.
3. The Initialization Page will now be displayed. If the date and time are incorrect by more than 10 minutes, refer to section 4.2 of this Pilot's Guide. The right side of the screen should show the identifier of the nearest airport to the initial position, along with a radial and distance from that airport waypoint. Press F with the cursor flashing over Ok? to approve the Initialization Page.
4. The VFR page will now be displayed to notify you that the GPS is for VFR use only. Press F to approve this page.
5. A Data Base Page is now displayed showing the date the data base expires or the date it expired. Press F to acknowledge the information displayed on this page.

Page 9
KLX 135 Pilot’s Guide Introduction
6. The next page displayed will probably be a page showing the VHF communication frequencies for the airport you are at. For now, use the right outer knob to turn to the NAV page type (watch the lower left corner of the screen and the small bar at the bottom to know when you are there). Then use the right inner knob to select the NAV 2 page if not already there. The NAV 2 page shows your present position relative to a nearby VOR. Verify that this position is correct before proceeding.
7. Press the D button. A page with the words DIRECT TO is now displayed on the screen.
In step 8 you will enter the ICAO identifier of the airport. The identifier will have a "K" prefix for a Continental U.S. airport, a "C" prefix for a Canadian airport, or a "P" prefix (in some cases) for an Alaskan airport if the identifier is all letters. For example, LAX becomes KLAX. For these countries if the identifier contains any numbers, there is no prefix. For example, TX04 is entered TX04. For other areas of the world the airport identifier should be entered identically to how it is charted.
8. Rotate the right inner knob until the first character of the airport identifier is displayed. Turn the right outer knob one step clock­wise to move the flashing segment to the second character position. Rotate the right inner knob to select the second charac­ter of the identifier. Use this procedure to enter the complete airport identifier.
9. Press F. The display will change to a page showing the identi­fier, name, city, and state/country of the airport just entered. Confirm that the correct airport is displayed. Press F a second time to approve the airport data.
10. A Navigation page is now on the screen. It displays the distance, groundspeed, bearing, and ETE to the destination airport. In addition, it displays a course deviation indicator (CDI).
See--wasn't that easy?

KLX 135 Pilot’s Guide System Components
1. KLX 135 SYSTEM COMPONENTS
A basic KLX 135 system consists of a panel mounted KLX 135 GPS/COMM and a GPS antenna. An altitude input is required to obtain full navigation and operational capabilities. Additional system components may be added or interfaced to the KLX 135 which increase its features and capabilities. Some of these optional compo­nents include an external course deviation indicator (CDI) or horizontal situation indicator (HSI), ARTEX ELS-10 emergency loca­tor transmitter (ELT), autopilot, and external annunciators.
The KLX 135 panel mounted unit contains the GPS sensor, the navi­gation computer, a COMM transceiver, a liquid crystal display (LCD), and all controls required to operate the unit.
Installation of an appropriate VHF communication antenna (capable of receiving 118.000 to 136.975 MHz) is required. However, the VHF COMM antenna is not included as part of the KLX 135 system.
The GPS “patch” antenna is available for use with the KLX 135. It is designed to always be mounted on the top of the aircraft.
The KLX 135 has analog outputs to drive the left-right deviation bar of most mechanical CDIs and HSIs. In addition, the NAV mode of the Bendix/King KFC 150, KAP 150, KAP 150H, KAP 100, KFC 200, KAP 200, KFC 250, KFC 275, KFC 300, and KFC 325 flight control systems may be coupled to the KLX 135. Many other autopilots may also be coupled to the KLX 135. Actual autopilot performance and capability when coupled to the KLX 135 may vary significantly from one autopilot model to another.
System Components
Chapter 1
Altitude may be provided to the KLX 135 from an encoding altimeter or blind encoder. Altitude is used as an aid in position determination when not enough satellites are in view.
Some installations may require remote annunciators to be mounted in the aircraft panel in order to indicate the status of certain KLX 135 functions, namely waypoint alert and message.

2.DATA BASE

2.1. DATA BASICS

The data base provides two primary functions. First, it makes pilot interface with the GPS sensor much easier. Rather than having to manually look up and then enter the latitude and longitude for a spe­cific waypoint, it allows you to merely enter a simple waypoint identifier. The data base automatically looks up and displays the lati­tude and longitude associated with the identifier. It should be obvious that the data base saves a lot of tedious latitude/longitude entry and also greatly reduces the potential for data input mistakes.
The second function of the data base is that it serves as a very con­venient means to store and easily access aeronautical information. Want to know the name of the airport, the nearest city, or the airport altitude? Just unleash the power of the KLX 135 and display the information right on the screen.

2.2. DATA BASE CONTENTS AND COVERAGE AREAS

There are two data base coverage areas available for the KLX 135. One is referred to as the “North American” data base and the other is referred to as the “International” data base.
Data Base
Chapter 2
The International Civil Aviation Organization (ICAO) and Aeronautical Radio, Inc. (ARINC) break the world into the ten geographic regions shown in figure 2-1. The KLX 135 North American data base con­tains aeronautical information for the group of ICAO regions consisting of Canada, USA, and Latin America. Likewise, the International data base also provides information for the group of ICAO regions consisting of Europe, East Europe, Africa, Mid East, Pacific, South Pacific, and South America.
Both data bases contain complete information for all VORs and NDBs in their respective coverage area. The data base also contains public use and military airports which have any runway at least 1000 feet in length.

KLX 135 Pilot’s Guide Data Base

2.3. ICAO IDENTIFIERS

Waypoints are stored in the KLX 135 database almost exclusively by their ICAO identifiers. ICAO (International Civil Aviation Organization) is an internationally accepted reference for the data. In almost all cases the proper ICAO identifiers may be taken directly from Jeppesen Sanderson or government aeronautical charts.
Airport identifiers in the contiguous United States, Alaska, and Canada are special cases in the ICAO system. Many airport identi­fiers for these areas have four letters beginning with a prefix letter that corresponds to the geographic area in which it is located. The prefix letter for the contiguous U.S. is “K”. Thus, the identifier for Dallas/Fort Worth International Airport is KDFW, not DFW (which would be identical to the VOR identifier). Likewise, the identifier for Orlando Executive Airport is KORL while the VOR identifier if ORL. The prefix letter for Canada is “C” and for Alaska is “P”.
NOTE: There are several exceptions in Alaska. In many cases, air­ports with three letter identifiers receive the prefix “P”, but there are many that don’t. The most reliable method of determining an Alaska airport identifier is to look it up from the airport name or city. See sec­tion 4.7.4, “Selecting Waypoints by Name or City”.
Incidentally, you can program the KLX 135 to default to a certain letter (such as “K”) when you are entering a waypoint identifier. See
section 4.4.2, “Data Entry” to learn about this handy feature.
Data Base
Chapter 2
Not all airport identifiers receive the prefix letter. Airport identifiers which are combinations of letters and numbers do not apply to the prefix rule. Examples of airport identifiers not using the prefix are 3C2, 7TX6, and M33.
So remember, if you are entering or looking for an airport identifier that is all letters (no numbers) then it will begin with a “K” prefix in the contiguous U.S., a “P” in Alaska (in some cases), or a “C” in Canada. If there are numbers in the identifier then a prefix is not used. For other areas of the world the airport identifier stored in the KLX 135 data base is identical to how it is charted.

2.4. UPDATING THE DATA BASE

The information stored in the data base would eventually become obsolete if there wasn’t some means to update it. For example, new airports open, navaids can move or change frequency, communication frequencies can change, and on and on.
2-3
Effective Date 3/94006-08751-0000 Rev 0
Page 18
Data Base
The data base is updated by means of a 3.5-inch diskette supplied by AlliedSignal and an IBM-compatible personal computer. This method does not have to involve removing the KLX 135 from the aircraft’s instrument panel. A jack, usually mounted in the aircraft’s instrument panel, provides a means of interfacing the KLX 135 with the comput­er via an interface cable. The diskettes are not returned to AlliedSignal.
Every 28 days, AlliedSignal receives new NavData information from Jeppesen Sanderson. This information is processed and down­loaded onto diskettes. AlliedSignal makes the update service available to you in a choice of several subscription or random update programs. See section 2.6 for details on these programs.
NOTE: AlliedSignal sends the update so that it arrives prior to the
Chapter 2
Data Base
next effective date. The new update may be installed any time prior to the effective date and the KLX 135 will use the previous data up to the effective date and automatically begin using the new data on the effective date.
In order to use the update program you must have access to a com­puter having a disk drive capable utilizing 3.5-inch 1.44 megabyte high density diskettes. If you wish to perform updates in the cockpit, an optional PC Interface kit must be used. Included in the kit is an interface cable that plugs into both the computer and into the data loader jack. The data loader jack is included with the KLX 135 installation kit and is typically installed in the aircraft’s instrument panel.
CAUTION: The data base must be updated only while the air­craft is on the ground. The KLX 135 does not perform any navigation function while the data base is being updated. Since a data base update takes approximately 10 minutes it is a good idea to turn off all electrical equipment on the aircraft except for the KLX 135 to avoid running down the aircraft battery.
NOTE: The diskettes sent to you can only be used to update one
KLX 135, although they can update that specific unit numerous times. The first time the diskettes are used in an update operation, a unique identification code from the KLX 135 being used is uploaded to the diskettes. These diskettes may be used in this specific KLX 135 an unlimited number of times which could be required if you switch back and forth between the North American and International data bases during one update cycle. These diskettes may not, however, be used to update other KLX 135s. This update protection ensures that Jeppesen Sanderson is properly compensated for the use of their NavData.

To update the KLX 135 data base:
1. Plug the 9 pin female connector end of the interface cable into a COM serial port of the computer. If the computer has COM 1 and COM 2 serial ports, either may be used. Some computers use a 9 pin COM serial port connector while other computers use a 25 pin connector. If the computer being used has a 9 pin con­nector, the interface cable connector will plug directly into the computer’s 9 pin connector. If the computer’s COM serial port uses a 25 pin connector, use the 25 pin to 9 pin adapter included in the PC interface kit to adapt the interface cable’s connector to the computer’s connector.
2. If you are using the PC interface kit in the cockpit, plug the other end of the interface cable (4 conductor male connector) into the data loader jack that is mounted in the aircraft panel.
3. Insert the diskette into the computer’s disk drive. Turn on the computer being used for the data base update. The program on the disk will automatically “boot” (load) and the computer screen will display “Ready” when the computer is ready to continue with the data base update operation.
4. Turn on the KLX 135. Press F as required to approve the Self Test, Initialization, VFR, and Data Base pages. Use the right outer knob to select the Setup (SET) type pages and the right inner knob to select the SET 3 page (figure 2-2).

KLX 135 Pilot’s Guide COMM Operation

3.COMM OPERATION

This section describes the use of the VHF Communication Transceiver portion of the KLX 135. If you are not yet familiar with the procedure of turning on and initializing the KLX 135, see section
4.2, “Turn-on and Self Test”.

3.1. ENTERING FREQUENCIES

3.1.1. FREQUENCY SELECTION

The KLX 135 is capable of tuning VHF communication frequencies from 118.000 MHz (megahertz) to 136.975 MHz.
To tune a COMM frequency:
1.Use the left outer knob to select the desired number of megahertz between 118 and 136. In figure 3-1, the frequency 122.90 MHz is desired.
2.Make sure the left inner knob is pushed in, and use it to complete the desired frequency. In this case, the left inner knob changes the frequency in increments of 0.05 MHz (50 kHz) (figure 3-2). Note that the left inner knob must be rotated three clicks clockwise to go from 122.75 MHz to 122.90 MHz.

3.1.2. STANDBY FREQUENCY ENTRY

The default frequency entry mode is standby frequency entry. In the standby frequency entry mode, both the active and standby commu­nication frequencies are displayed, and any frequency tuning is performed on the standby frequency.
To tune a COMM frequency using the standby frequency entry mode:
1.Use the left knobs to tune the standby COMM frequency, such as
122.90 MHz (figure 3-2 above).
2.To exchange the active and standby frequencies, press the A(flip-flop) button (figure 3-3).

3.1.3. ACTIVE FREQUENCY ENTRY

You can also tune the KLX 135 active frequency directly.
To tune a COMM frequency using the active frequency entry mode:
1. Press and hold the A button for approximately 2 seconds. The standby frequency will disappear and the active frequency will be the same as before you pressed the A button (figure 3-4).
2. You can now use the left knobs to tune the active COMM frequency.
3. To change back to standby frequency entry mode, press the A button momentarily.

3.1.4. 25 KILOHERTZ CHANNEL SPACING OPERATION

Some communication frequencies are multiples of 25 kilohertz (for example 125.975 MHz). KLX 135 allows you to easily tune these frequencies.
To tune a 25 kHz COMM frequency:
Chapter 3
1. Pull the left inner knob out.
COMM Operation
2. Use the left knobs to tune the frequency. Notice that the KLX 135 only displays two digits after the decimal point, so it has to cut off the last digit. For example, in figure 3-5 the standby frequency is
123.125 MHz and the KLX 135 displays 123.12.
Figure 3-4
Figure 3-5
3. When you’re ready to go back to 50 kHz tuning, push the left inner knob back in. This will allow you to select frequencies with fewer turns of the knob.

KLX 135 Pilot’s Guide COMM Operation

3.1.5. USING QuickTune™ FREQUENCY SELECTION

The KLX 135 gives you the ability to look up an airport VHF communication frequency from the navigation data base and load it directly into to COMM transceiver. That way, you don’t have the risk of getting the wrong frequency or making a tuning error. The QuickTune™function is accessible on the Airport 4 (APT 4) page. You may also use the Active 4 (ACT 4) page, if the active waypoint is an airport (see section 4.10.3).
To tune a COMM frequency from the data base:
1.Use the right outer and inner knobs to locate the APT 4 (orACT4, if the active waypoint is an airport) page for the facility you desire to communicate with (figure 3-6). The APT 4 page displays the frequency type (TWR = Tower Frequency, GRND = Ground Control, PCL = Pilot-con­trolled Lighting, etc.) and frequency.
2.Press the Bbutton to turn the cursor on and use the right outer knob to scan through all the airport’s frequencies (figure 3-7). There may be more frequencies than can be displayed at one time.
3.When you have the cursor over the desired frequency, press F and that frequency will become the standby frequency in the COMM transceiver (figure 3-8). The cursor turns off automatically.

3.2. RECEIVE/TRANSMIT ANNUNCIATION

The KLX 135 display tells you when it is receiving and transmitting! When you key the mic and the KLX 135 COMM transmits, a small “T” is displayed above the active frequency (figure 3-9). One instance where this is nice is if you have multiple COMM transmitters in the aircraft, it tells you when you are transmitting on the KLX 135. Whenever the KLX 135’s receiver breaks the squelch, an “R” is displayed in the same spot (figure 3-10). If the volume happens to be turned down low on the KLX 135, your audio panel, or your headphones, you may not hear the audio, but you will see the “R” annunciation. Note that you can’t receive and transmit at the same time.

3.3. VOLUME ADJUSTMENT AND AUTOMATIC SQUELCH OVERRIDE

The small knob in the upper left corner of the KLX 135 is not only the ON/OFF switch, it is used to adjust the COMM audio volume. By pulling this knob out you can override the automatic squelch, either to receive a distant, weak signal or to give you a noise reference to adjust the volume by.
Chapter 3

3.4. STUCK MICROPHONE PROTECTION

COMM Operation
Figure 3-10
Figure 3-9
Occasionally, a microphone switch can get stuck in the “on” position. When this happens, you can jam the frequency. To prevent this, the KLX 135 automatically shuts down the transmitter whenever it is keyed for more than 35 seconds at a time. When this happens, the COMM frequency display area is replaced with a flashing Stuck Mic message (figure 3-11) until the microphone key is turned off.
When this is the case, tuning the COMM with the left knobs or press­ing the flip-flop button will cause the words Stuck Mic to be removed, allowing you to see what you are tuning. This is helpful if you desire to listen to a different frequency than you were when the microphone got stuck. Five seconds after you stop adjusting the frequency in any way, the Stuck Mic message will reappear.
If you are intentionally making a lengthy transmission and Stuck Mic is displayed, simply release the microphone key for an instant and then resume your transmission.

3.5 BLIND TUNING FEATURE

Turning the unit on while holding the flip-flop (A) button will bring the KLX 135 up in the active frequency entry mode, loading 120.00 MHz into the active COMM frequency (figure 3-12). This allows the pilot to “blind-tune” the radio in the event of a display failure.
The COMM standby frequency will also be 120.00 MHz, although it is not displayed during active entry.
To accurately tune the active frequency on the COMM, count up 1 MHz for each clockwise click of the left outer knob, and down 1 MHz for each counterclockwise click of the knob. Similary, count up or down 50 kHz or 25 kHz per click of the left inner knob, depending on whether it is pushed in or pulled out.
IMPORTANT NOTE: In order to have the ability to change the COMM frequency, the pages of the turn-on sequence (Self-Test, Initialization, VFR, and Data Base) must be approved. Hold the A button down for about two seconds after appliying power to the KLX 135. Then, wait about 20 seconds and press the F button four times to approve these pages.

4.2. TURN-ON AND SELF TEST

Well, it’s time to get down to business and actually use the KLX 135!
Figure 4-1 can be folded out and used as a reference during the
following procedures. This is especially handy if you’re learning while away from your GPS. The steps below take a lot of words to explain, but before you know it, you will be “flying” through them.
NOTE: When power is applied to the KLX 135 it always “wakes up” in the En route-Leg mode. Only the En route-Leg mode is described in this chapter. In this mode the KLX 135 performs great circle navigation (the shortest distance between two points located on the earth’s surface). The course deviation output displayed on the unit’s internal course deviation indicator (CDI) and provided to an external horizontal situation indicator (HSI) or CDI is five nautical miles (full scale sensitivity) left and right. The other mode is En route-OBS and is described in section 5.3.3.

5. The next page displayed will be the Initialization page (figure 4-6). Verify that the date displayed in the top left corner of the Initialization page is correct. The KLX 135 has an internal battery powered calendar/clock, so the date and time normally don’t require setting. The battery has a life of approximately 3 years. In addition, the KLX 135’s system date and time are automatical­ly updated very precisely when at least one satellite is being received. However, if for some reason the date or time are incor­rect, it is necessary to enter the correct date or time so that the KLX 135 can reach the navigation mode. The date must be cor­rect and the time must be correct within ten minutes so that the KLX 135 will start looking for the correct satellites.

If the date is incorrect, rotate the right outer knob counterclockwise until the cursor is over the entire date field (figure 4-7). Rotate the right inner knob until the correct day of the month is displayed (figure 4-8). Then, move the cur­sor to the month field by rotating the outer knob one click clockwise and change the month as necessary. Use the same methods to select the correct year (figure 4-9).

Once you have selected the desired time zone, position the cur­sor over the entire time field and select the correct hour with the right inner knob (figure 4-12). Since 24 hour time is used, be sure to add 12 if the time is after 1:00 P.M. (2:30 P.M. becomes
1430). Now move the cursor to the tens of minutes position and select the desired value, and repeat this process for the last digit of the time field. When the correct time has been entered (figure 4-13), press F to start the clock running. Don’t worry that you can’t update the seconds. The KLX 135 system time will automatically be correct­ed very precisely once a satellite is received.
7. To aid the GPS receiver in acquiring your position, it is vital that it have a reasonable idea of where you are, and the Initialization page is where you have the chance to set this initial position. Check to see if the displayed initial position is where you actually are. This latitude/longitude is the last known position before the power was shut down the last time. Unless the unit has been moved since its last use, this position should be correct. On the right side of the screen will be the identifier of the nearest airport in the database, with a radial and distance from that airport. If you need to change the initial position to—let’s say—John F. Kennedy International (KJFK), move the cursor to the WPT: field and use the right inner knob to select a K as the first character of the identifier (figure 4-14). Move the cursor to the right one character and select a J and then right again to select an F. The final K should be filled in by the data base (figure 4-15). When you press F, the latitude and longitude fields will change to those of KJFK (figure 4-16). If necessary, the latitude and longi­tude may be entered manually.

After you get your COMM frequencies ready to go, you’ll probably want to check the NAV 2 page to see your present position. Use the right outer knob to select the NAV page type and then the right inner knob, if necessary, to select the NAV 2 page. It is quite likely that the present position will be dashed at first (figure 4-20). It takes the KLX135 several minutes to acquire the GPS satellites and to make its initial calculation of your position. When the KLX135 reaches a NAV ready status and is able to navigate, the NAV 2 page will display your present position relative to the nearest VOR (figure 4-21). Verify that the present position shown on the NAV 2 page is correct.
NOTE: In order to reach a Nav ready status, the aircraft must be away from obstructions blocking the GPS antenna’s view of required satellites. If the KLX 135 fails to reach a Nav ready status within five minutes refer to section 4.6, “Initialization And Time To First Fix”.

The KLX135 uses a Liquid Crystal Display (LCD). In normal opera­tion, the display screen is divided into two segments by a vertical line, called the page divider. In some cases, such as the display of system messages or the turn-on and self test sequence, the page divider disappears and you have a “full-screen” page.
Aeronautical information (or
data
) is presented on the screen in the form of “pages”. A page is a presentation of specific data in an organized format. Various page “types” are used to display related kinds of data. For example, one page type is NAV (navigation). NAV pages show information such as distance, groundspeed, bearing, course, and other data relating to navigation. Another page type is APT (airport). APT pages contain information pertinent to a specific airport such as name, city, State, elevation, and direction and dis­tance relative to the aircraft’s present position.
In normal operation, the aeronautical data is displayed on the right side of the screen. The active and standby COMM frequencies appear in the upper left corner of the display. The active frequency is

You might think of the page types as the chapters in a book and the page numbers as the pages within a chapter. Just as a chapter in a book may have from one to many pages, a KLX135 page type may have from two to 10 pages associated with it. There are, for example, 10 flight plan pages (FPL 0, FPL 1, FPL 2, ..., FPL 9) in the flight plan page type and four airport pages (APT 1, APT 2, APT 3, APT 4) in the airport page type.
Figure 4-23 shows an example of an APT 4 page. Notice the “+” sign in the page identification. Whenever a “+” sign is part of a page identifier there will be two or more pages, all having the same page number, used

The lower left corner of the display, where the page type and number are usually displayed, can also display short operational messages to the user called “scratchpad messages”. These messages are displayed for approximately five seconds, then this area returns to the page type and number. Figure 4-27 shows an example of a scratchpad message indicating a duplicate identifier. A complete listing of scratchpad messages is available in
Appendix C of this Pilot’s Guide.

4.4. BASIC OPERATION OF PANEL CONTROLS

The KLX 135 controls are very easy to use. Most of the page selec­tion and data entry is done with the knobs on the right side of the front panel and the cursor (B) button immediately above them. The knobs on the left side and the flip-flop (A) button above them control the communication transceiver. There are four buttons across the bottom: C(Message), D(Direct To), E(Clear), and F(Enter). The operation of these four buttons will be described on the next few pages.
The cursor is an area of inverse video (light characters on a dark background) on the screen. Many pages allow you to add, delete, or change data on the screen by first pressing the Bbutton to turn the cursor function on and bring the cursor on the screen. The right knobs are then used to enter or change data. When the cursor is on the screen, the lower left corner of the screen will show CRSRin inverse video rather than the page name for that particular page (figure 4-28). The cursor is over Present Posn.
There are times when the cursor is flashing. Figure 4-29 shows an example of how “whiskers” are used in this Pilot’s Guide to depict a flash­ing cursor (over ATIS 125.15) in addition, it shows an example of how “whiskers” around normal text is used to depict normal (non-inverse) char­acters flashing. The letters Entare flashing but are not in inverse video.

4.4.1. PAGE SELECTION

It is now time to learn to select a desired page.
NOTE: The cursor function is not used in selecting pages and the
B
button should not be pressed at this time. If CRSR is annunciat­ed in the lower left corner of the display, press the Bbutton to turn the cursor function off.
The right outer knob is rotated to select one of ten page types for the display. These ten page types are the following:
Chapter 4
Basic GPS Operation
Effective Date 3/94 006-08751-0000 Rev 0
4-10
Page 42
KLX 135 Pilot’s Guide Basic GPS Operation
Remember that the page type is displayed at the lower left corner of the screen. The first three letters of the page type are always used for annunciation on the screen, for example, CALrepresents Calculator page. The page type is also annunciated by means of a bar on the display, which moves as you turn the right outer knob. All the page types are listed across the front panel directly under the dis­play, and the bar will always be over one of them. For example, let’s say you were on a NAV page (figure 4-30) and you wanted to turn to a SET page. You would look at the list and see that the SET pages are three places to the right of the NAV pages. Therefore, turning the right outer knob three clicks clockwise will get you to the SET pages (figure 4-31). The annunciator bar and the page labels work kind of like a map to get you from one page type to another. The page type selection wraps around from Other (OTH) to Airport (APT); that is, the knob has no mechanical stops.
Once you have selected the desired page type using the right outer knob, you may select the page number by rotating the right inner knob. Let’s use an example to make sure you understand. You are presently viewing the APT 2 page and you wish to view the NAV 3 page. Rotating the right outer knob 5 (five) clicks clockwise will display the NAV page that you last viewed—we’ll say the NAV 2 page. Turning the right inner knob one click clockwise or three clicks counterclockwise will bring you to the NAV 3 page. Got it?
NOTE: In this Pilot’s Guide the right smaller knob is assumed to be in the “in” position unless it specifically states that he knob should be in the “out” position. Therefore, the words “rotate the right inner knob” mean to turn the right inner knob while the knob is in the “in” position.

4.4.2. DATA ENTRY

Now that you’ve learned how to select the desired page, you’re ready to learn the means of entering data. It is necessary to enter data, for example, in order to specify a waypoint of your choice to go Direct To. The general procedure for entering a waypoint identifier is described below and is shown in figures 4-32 through 4-40 for enter­ing a waypoint (in this case, First Flight airport in North Carolina, identifier KFFA) on the Calculator (CAL) 1 page.

Often, you will find yourself entering airports that begin with the same character over and over again. In section 2.3, you learned how the KLX135 uses ICAO identifiers, which means that many U.S. airport identifiers begin with the letter K. Also, many airport identifiers in Europe begin with the letter E or the letter L. Especially when flying VFR, you will mostly want to enter airports as Direct To or Flight Plan waypoints. The KLX 135 has a great feature that will save you turns of the knob when you know that the first character will probably be a K, E, L, or other letter that is commonly used in your part of the world. You can set the default first waypoint identifier character on the SET 5 page.
To change the default first waypoint identifier character:
1.Select the SET 5 page (figure 4-41) and turn on the cursor (B) (figure 4-42).
2.Use the right inner knob to select the desired character (figure 4-43), such as a K in the U.S., a C in Canada, a P in Alaska, an E or an L in Europe, etc.

4.4.3. THE DUPLICATE WAYPOINT PAGE

There are some waypoints in the data base whose identifiers are not unique. That is, more than one waypoint has the same identifier. When a waypoint identifier has been entered which is not unique to a single waypoint, a Duplicate Waypoint page appears on the screen. The Duplicate Waypoint page is used to select which of the waypoints having the same identifier is actually desired. The waypoint identifier is displayed on the top left of the page. To the right of the identifier is the number of waypoints in the data base having the identifier. Below the identifier is a list of the waypoint types (APT, VOR, NDB, USR) and the associated countries which use the identifier.
To see an example of a Duplicate Waypoint page, try entering the identifier “D” as a Direct To waypoint or a Flight Plan Waypoint:
Figure 4-44

5. Press F and the display will change to the waypoint page for the selected waypoint (figure 4-48).
6. Press F again to approve the waypoint page.

4.4.4. CYCLIC FIELDS

On many of the KLX 135 pages, there are ceded by a carat (>). A cyclic field is one that you as the pilot can select from two or more options. For exam­ple, in figure 4-49, the field >135°To (magnetic bearing to Austin VOR) is a cyclic field. In this case, the second option is the magnetic radial from Austin VOR to present position.
To change a cyclic field:
1. Turn on the cursor by pressing the B button (figure 4-50).
2. Using the right outer knob, move the cursor over the cyclic field you wish to change (figure 4-51).

NOTE: The cyclic field which always appears on the left side of the display is the navigation mode selector/annunciator. In most cases, it will display >Leg indicating en route-leg mode (figure 4-52). The other choice is the en route-OBS mode, in which the magnetic selected course is displayed here (figure 4-53). You can move the cursor to this cyclic field by turning the cursor all the way counterclockwise. See section 5.3 for more details on navigation modes.

4.5. MESSAGE PAGE

Whenever the KLX 135 wants to get your attention, the message prompt (a large “M” on the left side of the screen, just below the COMM frequencies) begins flashing (figure 4-54). If you have a remote message annunciator in your aircraft, it will also begin flashing at that time. You should view the message at your earliest opportunity because the unit may be alerting you to some situation of immediate concern to its condition or to your flight.

KLX 135 Pilot’s Guide Basic GPS Operation

4.6. INITIALIZATION AND TIME TO FIRST FIX

Since the KLX 135 stores its position and other required parameters in memory when power to the unit is removed, it is seldom necessary to aid the unit in reaching a NAV ready condition. The time required from power on until the KLX 135 determines its present position and is therefore ready to navigate is called “time to first fix.” The time to first fix is normally a few minutes or less. In order for the KLX 135 to reach a NAV ready condition, it is necessary to meet the following conditions:
1. The KLX 135’s “almanac” data must be current. Almanac data is orbital information for all the satellites and is used for initial acquisition when the KLX 135 is first turned on. This data is stored in the KLX 135’s non-volatile memory and is considered current for up to six months. Each satellite sends almanac data for all satellites. Since the KLX 135 routinely updates the almanac data during normal operation, the almanac data will become out of date only if the KLX 135 hasn’t been used for the previous six months or longer. Collecting new almanac data takes place automatically if the data is more than six months old. The process of acquiring new almanac data is called a “Search The Sky” start-up. The Search The Sky process requires that the KLX 135 be turned on for a period of from 12.5 to 20 minutes and that at least one satellite be in view. The Self Test, Initialization, and Data Base pages should be approved. Almanac data is being collected as long as the Other 1 (OTH 1) page displays SRCH in the upper right corner. In addition, the message alert will flash indicating there is a message to be viewed. If you press the C button the message page will display a message stating:
*Search the Sky
Acquisition Started
Basic GPS Operation
Chapter 4
Press C again to return to the previous page. The message will remain active while the almanac data is being collected.
2. The aircraft must be located such that the GPS antenna has an unobstructed view of the sky so that required satellite signals are not being blocked. If possible, position the aircraft away from hangars or other obstructions.
3. The date and time displayed on the Initialization page or SET 2 page should be within 10 minutes of actual time. Date and time are seldom a practical concern because the KLX 135 contains a battery backed up calendar/clock. In addition, once a satellite is
4-17
Effective Date 3/94006-08751-0000 Rev 0
Page 49
Basic GPS Operation
being tracked, the KLX 135’s system time is automatically updat­ed to UTC (Zulu) time. However, if the time displayed on the Self Test page or the SET 2 page is in error by more than 10 minutes it is necessary to enter a correct time. See section 4.2, “Turn-On And Self Test.”
4.The aircraft’s position should be within 60 nm of where the KLX135 last had a valid position. If the distance is greater than 60 nm the KLX 135’s position should be “initialized” on either the Initialization Page (section 4.2), or the SET 1 page. Since the KLX 135 stores its position when power is removed, it is usually not necessary to initialize the position when power is later reap­plied. However, initialization may be required, for example, if the KLX 135 was not turned on for a flight or if it stopped navigating somewhere along the last flight due to a lack of adequate satellite coverage. If there is any doubt about whether or not to initialize, go ahead and do it! It’s no big deal and it takes just a moment.
To initialize the position from the SET 1 page:
1.If the cursor is not on the screen (figure 4-56), press the B button to bring it on the page over the INIT POSfield (figure 4-57).
2.Using the right inner and outer knobs, enter the identifier for the airport where you are presently located or the identifier of a navaid or other airport which is close to your present position (fig­ure 4-58). Any waypoint in the data base which is within 60 miles is acceptable, but the closer the

better. Remember, if you are entering an airport identifier that is all letters (no numbers), then it will begin with a “K” prefix in the contiguous U.S., a “P” in Alaska (in some cases; in others, the prefix is not added), or a “C” in Canada. If there are numbers in the identifier then a prefix is not used. Outside the contiguous U.S., Alaska, and Canada, use the airport identifiers as they are charted.

4.7. SELECTING AND SCANNING WAYPOINTS

There are four types of waypoints: airports, VORs, NDBs, and user waypoints. Waypoints in the published data base fall into one of the first three types. You can create up to 250 user waypoints to supplement the waypoints in the database (see section 5.2.1 to create a user waypoint).
There are three methods you may use to select a specific waypoint for viewing. You may enter the waypoint’s identifier directly, you may scan through the waypoint identifiers in alphabetical order, or you may enter the waypoint’s name. If the waypoint is an airport, you may also select it by entering the city where the airport is located.

4.7.1. SELECTING WAYPOINTS BY IDENTIFIER

The most direct way of selecting a specific waypoint is to simply enter the waypoint’s identifier directly on the appropriate waypoint page type (APT, for example). Let’s use Chicago O’Hare International Airport whose identifier is KORD as an example.
To select a waypoint by identifier from a waypoint page:
1.Use the right outer and inner knobs to select the Airport 1 (APT
1) page (figure 4-62). (Actually, the airport identifier can be entered on any of the three Airport pages but we’ll use the APT 1 since it displays the airport

2.Turn on the cursor (B) and make sure the right inner knob is

pushed in. The cursor will appear over the first character of the air­port identifier (figure 4-63).

Notice that as you turn through letters, the KLX 135 automatically fills in the identifier of the first waypoint in alphanumeric order in the database which matches what you’ve entered so far (in this case, Hall Airport in Kaufman, Texas). Go ahead and experi­ment a little bit.
4. Use the right outer knob to move the cursor to the second character and select an “O” (figure 4-65).
5. Use the same process to select an “R” and then a “D” (figure 4-66). You are now view­ing the APT 1 page for KORD.
The KLX 135 feature of filling in characters of the identifier can be a time saver! For a second example, let’s select Bloomington VOR whose identifier is BMI.
More selecting a waypoint by identifier:
Figure 4-65
Figure 4-66
1. Make sure you have turned the cursor off from the previous example. With the right knobs, select the VOR 1 page (figure 4-67).
2. Turn the cursor (B) on.
3. Change the first character to a “B” (figure 4-68).
4. Move the cursor to the second character and select “M” (figure 4-69). Eureka! When you entered the “M”, the KLX 135 searched its data base for the first VOR identifier beginning with the letters “BM” and found BMI. Many times you will only have to enter two or three characters of the waypoint identifier and the KLX 135 will furnish the rest.
5. Turn off the cursor (B).

4.7.2. SELECTING WAYPOINTS BY SCANNING

You may also select waypoints by scanning through them. This may be done with the cursor either on or off.
To select a waypoint by scanning with the cursor off:
1. Select the page type for the waypoint you are looking for (APT, VOR, NDB, or SUP).
2. Pull the right inner knob to the “out” position.
3. Turn the right inner knob clockwise to scan through the waypoints in alphabetical order, or counterclockwise to scan in reverse alphabetical order. Remember that numbers are considered lower in order than letters. Thus, the airport identifier
KA2 comes before KAAF.
NOTE: The faster you turn the knob while scanning, the larger the
step through the waypoints. This variable rate scanning allows you to get from one end of the list to the other very quickly. When the knob is turned slowly, you will go through the waypoints one at a time.
You may also want to scan waypoints with the cursor on. This is especially useful if you remember the first part of the identifier, or if you wanted to scan all airports that start with a KL, for example. Let’s give it a try.
To select a waypoint by scanning with the cursor on:
1. Select the page type for the waypoint you are looking for (APT, VOR, NDB, or SUP). In this case, we want the APT 1 page.
2. Turn on the cursor (B). It will appear over the first character of the waypoint identifier. Select a K with the right inner knob.
3. Move the cursor one place to the
Chapter 4
Basic GPS Operation
right and select an L (figure 4-70).
4. Move the cursor one place to the right and pull the right inner knob out. The last two characters of the waypoint identifier will be in reverse video (figure 4-71).
5. Use the right inner knob to leaf through all the data base airports whose identifiers begin with KL.

4.7.3. “NEAREST” AND “COMPLETE” WAYPOINT SCAN LISTS

There are actually two waypoint scan lists for airports, VORs, and NDBs. These two lists are the “complete” list and the “nearest” list. The complete list contains all of the waypoints in the data base for a waypoint type (all the airports, for example). The nearest list consists of the nine nearest waypoints (of that type) to your present position. Therefore, if you are in the nearest airport list, it will contain the nine nearest airports relative to your location. There is no “nearest” list for supplemental waypoints (SUP).
The nearest list is positioned in front of the complete list. That is, you must scan backwards (turn the knob counterclockwise) through the complete list to reach the nearest list. You will know when you have reached the nearest list because the top middle portion of the waypoint page will flash the relative position of the waypoint to your position. “1” indicates nearest (figure 4-73) while “9” indicates the ninth nearest (figure 4-74). As you scan clockwise with the right inner knob “1, 2, 3, ..., 9”, the next scan position is the beginning of the complete list. The nearest list can only be reached by scanning back­wards. It does not wrap around after the last waypoint in the complete list.
Figure 4-73
Figure 4-74
Basic GPS Operation
Chapter 4
Waypoint pages displayed in the nearest list do not contain a latitude and longitude position as they do in the complete list. Instead, the bearing and distance to the waypoint (or the radial and distance from the waypoint) are displayed.
Once the nearest waypoint is being displayed, the other waypoint pages (for example, APT 2 and APT 3) for that airport are available for display by making sure the right inner knob is pushed in and then turning it to select the desired airport page.

Basic GPS Operation
4.7.3.1. Nearest Airports in an Emergency
In the event of an emergency, a special feature is provided to very quickly display the nearest airport to your present position and the rest of the nearest airport list.
To display the nearest airports in an emergency:
1.Press C, then press F.
2.The waypoint page for the nearest airport is now displayed on the screen. The right inner knob (in the “out” position), may now be used in the normal manner to scan the other nearest airports. With the right inner knob in the “in” position, you may view all three airport pages for a specific airport. Figures 4-73 and 4-74 show examples of nearest APT 1 pages.
4.7.3.2. Continuous Display of Nearest Airport
When the nearest airport page is initially displayed, “1” is displayed in the upper right hand corner of the page to designate this airport as the nearest airport. However, if you continue to fly along your flight plan with this page selected, the same airport will be displayed and its position in the nearest airport list will change from 1to 2, 3, 4... 9 until finally it won’t be in the nearest airport list at all. The reason for this is that in the event of an actual emergency once you have determined which airport you are heading for, you don’t want the nearest airport list to update while you are maneuvering or looking up data on the other airport pages for that airport.
There may be times, however, when you’re flying over “unfriendly” terrain when you wish to always have the nearest airport displayed on the screen.
To display the nearest airport continuously:
1. Display the nearest airport page by pressing Cfollowed by
Chapter 4
pressing F.
Basic GPS Operation
2. Turn on the cursor (B).
3. Rotate the right outer knob clockwise to position the cursor over “1” (figure 4-75). As long as the cursor is left in this position, this page will update so that the nearest airport is always shown as the flight progresses.

4.7.4. SELECTING WAYPOINTS BY NAME OR CITY

When you know the identifier of the desired waypoint you will use one of the two methods just described to select it. However, what if you know the name but you don’t know the identifier of your desired waypoint? You’re in luck because the KLX 135 will allow you to enter the first few characters of the name to help you find it in the data base. We will use a couple of examples to illustrate how this is done. For VORs and NDBs, you may use the navaid name. For airports, you may use the airport name or the city name (where the airport is located).
In this first example we want to view the information in the KLX 135 data base for Napoleon VOR (located just east of Kansas City) but we don’t remember the identifier for it.
To select a VOR or NDB by navaid name:
1. With the cursor off, use the right knobs to select the VOR 1 page (figure 4-76). The VOR waypoint in view is not important.
2. Press B and then make sure the right inner knob is pushed to the “in” position.
3. With the right outer knob, move the cursor over the first character in the VOR name which is being displayed (figure 4-77).
4. Change this first character to an “N” in this case (figure 4-78).

5. Move the cursor one space to the right and select the second char­acter, “A” (figure 4-79).
6. Select the third character, “P” (figure 4-80). Up pops Napoleon and its identifier, ANX!

4.8. DIRECT TO OPERATION

The Dbutton is used to initiate Direct To operation (navigation from your present position direct to your destination). When Dis pressed, the Direct To page will be displayed with a flashing cursor over a waypoint identifier (figure 4-85). The waypoint identifier which appears on the Direct To page is chosen by the KLX 135 according to the following rules:
1. If the Flight Plan 0 (FPL 0) page is displayed on the screen and the cursor is over one of the waypoint identifiers in FPL 0 when
D
is pressed, then that waypoint identifier will appear on the DIR page. You will appreciate this feature when you learn to use flight plans in section 4.10.
OR . . .
2. If there is any waypoint page (APT, VOR, NDB, SUP, or ACT page) in view when
D
is pressed, then the DIR page will
contain the identifier for the waypoint just viewed.
If neither condition above is occurring, then:
118.00 DIRECT TO:

3. When
D
is pressed, the waypoint identifier for the current
active waypoint will be displayed on the DIR page.
If there is no active waypoint when Dis pressed, then:
4. The Direct To page displays blanks in the waypoint identifier field. In order for there not to be an active waypoint, there is no Direct To waypoint and there are no waypoints in Flight Plan 0.
Now that you know the ground rules, let’s go ahead and try some

4.8.3. WAYPOINT ALERTING FOR DIRECT TO OPERATION

Approximately 36 seconds prior to reaching a Direct To waypoint, the arrow preceding the waypoint identifier on the waypoint page for the active waypoint will begin flashing. This arrow will also be flashing on any NAV or FPL page displaying the active waypoint identifier. This is called “waypoint alerting”. If an external waypoint alert annunciator is mounted in the aircraft, this annunciator will begin flashing at the same time.

4.9. CREATING AND MODIFYING FLIGHT PLANS

The following rules and considerations apply to KLX 135 flight plans:
The KLX 135 is capable of storing in its memory nine flight plans plus an active flight plan.
Each of the flight plans may contain up to 20 waypoints. The waypoints may consist of any combination of published waypoints from the data base or user created waypoints.
The flight plans are numbered 0 through 9 (FPL 0, FPL 1, FPL 2, . . . , FPL 9).
The active flight plan is always FPL 0. The standard procedure is to create a flight plan in one of the flight plans numbered as FPL 1, FPL 2, etc. When one of these numbered flight plans is activated, it becomes FPL 0, the active flight plan. This Pilot’s guide will refer to FPL 0 as the “active flight plan” and FPL 1 through FPL 9 as the “numbered flight plans.” If desired, a flight plan can be created directly in the active flight plan. This avoids creating the flight plan in a numbered flight plan and then having to activate it. The disadvantage is that if a numbered flight plan is subsequently made active, the one programmed directly into FPL 0 will be lost.
Basic GPS Operation
Chapter 4
Modifications may be made to FPL 0 without affecting the way it is stored as a numbered flight plan.
Unless Direct To operation is being used, the active flight plan (FPL 0) must contain at least two waypoints. Otherwise, the KLX 135 navigation system will be flagged.

4.9.1. CREATING A FLIGHT PLAN

A flight plan for a flight from Lakefront airport in New Orleans, LA. to St. Petersburg/Clearwater, FL. International airport will be used as an example of how to create a flight plan. The waypoints making up the flight plan are: KNEW(Lakefront airport), GPT(Gulfport VOR), SJI (Semmes VOR), CEW(Crestview VOR), MAI(Marianna VOR), TLH (Tallahassee VOR), CTY(Cross City VOR), and KPIE (St. Petersburg/Clearwater International airport).
To create a flight plan:
1.Select the flight plan (FPL) pages with the right outer knob.
2.Select a flight plan page (preferably other than FPL 0) which does not contain a flight plan (figure 4-96). If all of the flight plan pages contain flight plans, refer to section 4.9.6,

3.Turn on the cursor (B).
NOTE: The KLX 135 flight plan operation is designed so that the first waypoint in the flight plan should always be the departure point. Remember to enter the K, P, or C prefix for certain airports in the United States, Alaska (some, but not all cases), or Canada, respec­tively. See section 2.3, “ICAO Identifiers”.
4.Use the right inner knob to select the first character of the departure waypoint identifier (figure 4-97). If you have set the default first

10.When all of the waypoints have been entered in the flight plan, the right outer knob may be rotated to move the cursor up and down and manually “scroll” through the waypoints making up this flight plan. This is useful if the flight plan contains four or more waypoints since not all of the waypoints can be displayed at one time. When the right outer knob is rotated counterclockwise, the cursor may be positioned over Use?. If there are more than three waypoints in the flight plan, the first two waypoints will then be displayed followed by the last waypoint in the flight plan. Rotate the right outer knob to move the cursor and manually scroll to see the missing intermediate waypoints.
11.Turn off the cursor (B). Additional flight plans may now be created in the same manner.

4.9.2. VIEWING DISTANCE AND DESIRED TRACK BETWEEN STORED FLIGHT PLAN WAYPOINTS

The stored flight plan (FPL 1-9) pages have a field to the right of each waypoint in the flight plan. This field may be used to display the cumulative distance (Dis) to each waypoint or the magnetic desired track (Dtk) from the previous waypoint.
If you have more than three waypoints in the stored flight plan, you may wish to view flight data for waypoints which are not displayed on the screen. If this is the case, turn on the cursor (B) and use the right outer knob to scroll down the flight plan until the waypoint of interest is on the screen.
This display will default to the distance presentation at power-on. The area in the upper right hand corner of the screen is a cyclic field.
To cycle between distance and desired track display on a num­bered flight plan page:
1. Turn on the cursor (B); it will come up over the cyclic field, which in this case is displaying distance (Dis) in nautical miles (figure 4-102).
Figure 4-102
2. Press E. The cyclic field will change to magnetic desired track (Dtk) (figure 4-103). An additional E press cycles back to Dis.

4.9.4. ADDING A WAYPOINT TO A FLIGHT PLAN

A waypoint may be added to any flight plan containing fewer than 20 waypoints
To add a waypoint to a flight plan:
1. Turn on the cursor with the B button.
2. With the outer knob, position the cursor over the waypoint identi­fier which you desire to follow the waypoint being added. Another way to think of this is to position the cursor over the location in the flight plan you wish the new waypoint to be added. For example, if SJI is presently the second waypoint in the flight plan and you wish to insert GPT in the number 2 position in front of SJI, move the cursor over SJI
Figure 4-108
(figure 4-108).
3. Use the inner knob to enter the first character of the waypoint being inserted. As you begin to turn the knob, the existing waypoint in this position automatically jumps down to the next position. In this case, SJI automatically moves to waypoint 3 and KPIE changes to waypoint 8 (figure 4-109).

4.10. OPERATING FROM THE ACTIVE FLIGHT PLAN

4.10.1. GENERAL PROCEDURES

Everything you have learned in this Pilot’s Guide thus far is applicable to using the KLX 135 for flight plan operation. The following rules and considerations apply for flight plan operation while the KLX 135 is in the En route-Leg mode:
Always verify that you are viewing the active flight plan page (FPL 0) and not one of the other numbered flight plan pages.
The active leg of the flight plan is designated with a symbol. A leg is defined as the course line between a pair of waypoint (a “from” waypoint and a “to” waypoint). The head of the arrow is positioned to the left of and points to the active “to” waypoint. In figure 4-122, SLC (Salt Lake City VOR) is the “to” waypoint. The tail of the symbol is positioned to the left of the “from” waypoint. KPVU (Provo Municipal) is the “from” waypoint in figure 4-122. The symbol is not displayed unless the KLX 135 is actually receiving GPS signals suitable for navigation.

occurring. If it is desired to cancel the Direct To operation and operate from the active flight plan, press D, E, and then F.
As flight plan waypoints are reached, the active leg symbol auto­matically shifts to the next leg.
If the flight plan contains more waypoints than can be displayed on the screen at one time, the page will automatically scroll as progress is made along the flight plan so that the active leg is always displayed (figure 4-125).
The last waypoint in the flight plan is always displayed at the bot­tom of the FPL 0 page, even if all of the waypoints in the flight plan can’t be displayed on the page at one time. To view inter­mediate waypoints, turn the cursor on and use the right outer knob to manually scroll through all of the waypoints, as desired. If scrolling is performed all the way to the end of the flight plan, a blank waypoint position will exist so that a waypoint may be added to the end of the flight plan (figure 4-126).
Figure 4-125
Figure 4-126

4.10.2. TURN ANTICIPATION AND WAYPOINT ALERTING

Prior to reaching a waypoint in the active flight plan, the KLX 135 will provide navigation along a curved path segment to ensure a smooth transi­tion between two adjacent legs in the flight plan. That is, the CDI or HSI left/right deviation will be referenced to the dashed line in figure 4-127. This feature is called turn anticipation. The tran­sition course is based upon the aircraft’s actual groundspeed and the amount of course angle change between the two legs. The KLX 135 automatically sequences to the next leg after passing the midpoint in the transition segment.

Approximately 20 seconds prior to the beginning of turn anticipation, the arrow preceding the active waypoint identifier will begin flashing on the FPL 0 page and on any Navigation page or waypoint page displaying the active waypoint identifier (figures 4-128 and 4-129). This is called “waypoint alerting”. If an external waypoint alert annunciator is mounted in the aircraft, this annunciator will begin flashing at the same time.
To utilize the turn anticipation feature, start the turn transition to the next leg in the flight plan at the very beginning of turn anticipation. This occurs when the external waypoint alert annunciator stops flashing and goes on steady. At this time, the KLX 135 will notify you with a message on the Message page of the new desired track to select on your HSI or CDI.

4.10.3. VIEWING THE WAYPOINT PAGES FOR THE ACTIVE FLIGHT PLAN WAYPOINTS

The waypoint pages for each of the waypoints in the active flight plan may be easily displayed by selecting the Active (ACT) Waypoint page type. When the ACT page type is first selected, the waypoint page for the active waypoint will be displayed (figure 4-132). The location of the waypoint in the flight plan (waypoint 1, waypoint 2, etc.) is annunciated with a number to the left of the identifier. In addition, an arrow to the left of the waypoint number designates the active waypoint. If there is a letter to the far right of the identifier, it designates the type of waypoint: A = airport, U = user­defined waypoint. If the waypoint is a VOR or an NDB, the navaid frequency is displayed in this area (figure 4-133).
To view the waypoints in the flight plan that are not the active waypoint:
1. Pull the right inner knob to the “out” position and turn it to view each of the waypoints in the order they are contained in the flight plan (figure 4-134).
2. Once the desired waypoint is found, the right inner knob may be pushed back to the “in” position and rotated to display any of the other waypoint pages (figure 4-135).

3. Pulling the knob back out will allow further scanning of the waypoint pages in the active flight plan.

4.10.4. COMBINING DIRECT TO AND FLIGHT PLAN OPERATION

It is very common when using flight plan operation to use the Direct To function to proceed directly to a waypoint which exists in the active flight plan. For example, after takeoff on an IFR flight plan, it is

common to receive vectors in the terminal area and then be given a clearance direct to the first point in the flight plan that was filed. The KLX 135, as an advisory navigation source, makes this kind of operation very easy to accomplish. Whenever you do a Direct To operation to a waypoint which is in the active flight plan (FPL 0), the system will provide navigation to the waypoint and then automatically resume navigation along the flight plan when the Direct To waypoint is reached. Waypoints which exist prior to the Direct To waypoint in the active flight plan are bypassed. Of course, the active flight plan will never be resumed if the Direct To operation is to a waypoint which is not in the active flight plan.
Any of the several methods previously described for initiating Direct To operation may be used, although the one below is the easiest for this application.
To fly direct to a waypoint in the active flight plan (FPL 0):
1. Select the FPL 0 page.
2. Turn on the cursor (B) and use the left outer knob to position the cursor over the desired waypoint (figure 4-136).
3. Press D. The display will change to the Direct To Page (figure 4-137), with the identifier of the selected waypoint.

page, you will see that the active waypoint is now preceded by an arrow only, instead of the

4.10.5. VIEWING DISTANCE, ETE, ETA, OR DESIRED TRACK TO FLIGHT PLAN WAYPOINTS

The active flight plan (FPL 0) page has a data field to the right of each waypoint in the flight plan. This field may be used to display the cumulative distance (Dis) from the present position to each waypoint, the estimated time en route (ETE), the estimated time of arrival (ETA, for which the time zone abbreviation is displayed), or the magnetic desired track (Dtk) between each waypoint.
If you have more than four waypoints in FPL 0, you may wish to view flight data for waypoints which are not displayed on the screen. If this is the case, turn on the cursor (B) and use the right outer knob to scroll down the flight plan until the waypoint of interest is on the screen.
This display will default to the distance presentation at power-on (figure 4-139). The area in the upper right hand corner of the screen is a cyclic field, which means that . . .
To cycle between distance, ETE, ETA, and desired track on the FPL 0 page:
1.Turn on the cursor (B); it will come up over the cyclic field, which in this case is displaying distance (Dis) in nautical miles (figure 4-140).

4.11. NAVIGATION PAGES

As you would expect, the NAV (navigation) pages contain information relating specifically to the KLX 135’s navigation capabilities. The KLX135 has four NAV pages. The procedure for selecting specific pages, including the NAV pages, was described in section 4.4.1, “Page Selection”.

4.11.1. THE NAVIGATION 1 (NAV 1) PAGE

The NAV 1 page is the primary navigation display, and is shown in figure 4-146. In normal flight, you will probably want to view this page more often than any other. A NAV 1 page displays the following information:

a conventional CDI or HSI using VOR/Localizer navigation. An on­course indication is displayed when the vertical deviation bar is centered on the triangle in the middle of the CDI. In both modes (en route and OBS, see section 5.3), each dot represents one nautical mile deviation from the desired track. Therefore, the CDI shows course deviation five nautical miles left and right of course. A vertical deviation bar positioned two dots to the right of the center triangle indicates the aircraft is two nautical miles to the left of course (figure 4-149). The center triangle also serves as the CDI’s

But this presentation will show you exactly how far off course you are (figure 4-152). When the KLX 135 is not usable for navigation, the crosstrack distance will be dashed out (figure 4-153).
Line 3: Distance from present position to the active waypoint and the calculated groundspeed.
Line 4: A cyclic field which can display either bearing to the active waypoint (To) or radial from the active waypoint (Fr) relative to the present position. By placing the cursor over this field and pressing the E button, you may toggle between the two options.
NOTE: Due to “great circle” courses and magnetic variation differ­ences between present position and the active waypoint, the To bearing and From radial may not be exactly 180° different from each other when the system is in the Leg mode. This condition is most likely to occur when long distances are involved, and/or you are operating in very northerly or southerly latitudes. See figure 4-154 for an example depicting a case like this. The aircraft is somewhere over Georgia, and the active waypoint is KPHX. The bearing to steer is 269°, and radial is 72°. Generally, you will want to use bearing (not radial) when long distances are involved.

4.11.2. THE NAVIGATION 2 (NAV 2) PAGE

The NAV 2 pages in figures 4-155 and 4-156 display the aircraft’s present position in one of two formats. The first line is a cyclic field which allows you to toggle between formats. When the KLX 135 is first powered up, it defaults to present position in terms of the radial and distance from a nearby VOR. You can change the reference waypoint from the nearby VOR to any waypoint.
To change the NAV 2 page present position reference waypoint:
1. With the NAV 2 page on the radial and distance from a reference waypoint format, turn on the cursor (B) and move it to the Ref: field (figure 4-157).
2. Use the right inner and outer knobs to enter the waypoint you wish to use as a reference.
Figure 4-155

3. Press F. The waypoint page for the identifier just entered will be displayed.
4. If this is the waypoint you intend­ed, press F again. The display will return to the NAV 2 page (figure 4-158).
NOTE: If you change the reference waypoint, change to a page other than the NAV 2 page, then turn back to the NAV 2 page, the reference waypoint will revert back to a nearby VOR.
By turning on the cursor (B) over the first line and pressing E, you can change to the latitude and longitude format.

Line 2:The time of departure. This is the time when a valid ground­speed was first greater than 30 knots (typically during takeoff).
Line 3:Estimated time of arrival at your destination. If the active waypoint is not part of the active flight plan, the active waypoint will be the destination. Otherwise, the last waypoint in your active flight plan will be the destination.
Line 4:The elapsed flight time, which will be the hours and minutes since the departure time.

Line 3:Actual track (Track) — the aircraft’s present track over the ground. If you are trying to establish a heading on a new leg of your flight, it is very helpful to look at the difference between the actual track and the desired track, and adjust your heading accordingly to allow for crosswind.
Line 4:Bearing (Brg) — the magnetic bearing from present position to the active waypoint.

4.12. WAYPOINT PAGES

NOTE: Each of the waypoint page types includes a cyclic field which
displays present magnetic bearing to or magnetic heading from the waypoint. Due to “great circle” courses and magnetic variation differences between present position and the active waypoint, the To bearing and From radial may not be exactly 180° different from each other. This condition is most likely to occur when long distances are involved, and/or you are operating in very northerly or southerly latitudes. See section 4.11.1 and figure 4-154 for more details.

4.12.4. SUPPLEMENTAL WAYPOINT PAGES

The Supplemental waypoint pages (SUP 0, SUP 1, SUP 2, and SUP3) allow you to create “custom” waypoints for use in navigation. A crop sprayer might want to create a waypoint on a field that is sprayed regularly, for instance. Another candidate might be a small airport which is not included in the KLX 135 database. To learn how to create a user-defined waypoint, see section 5.2.1.

4.13. VIEWING AND SETTING THE DATE AND TIME

The KLX 135 system time and date should seldom, if ever, require updating because they are automatically updated when at least one satellite is received. In addition, the KLX 135 contains an internal battery powered calendar/clock to keep system time and date when the unit is not being used. You will normally check to make sure the KLX 135 is set to the correct time and date shortly after you turn the unit on while you verify the Self Test Page. You can, however, also check the time and date on the Setup (SET) 2 page anytime you desire. There are several pages as well as some internal functions of the KLX 135, such as magnetic variation and proper use of data base information, that depend on having the proper time and date.
NOTE: You will not be able to update the time or date if the KLX 135 is receiving a time and date from a satellite.
To set the date on the SET 2 page:
1. Select the SET 2 page (figure 4-185).
2. Turn on the cursor. The cursor will be over the entire date field (figure 4-186).
3. Select the correct day of the month with the right inner knob.
4. Move the flashing part of the cursor to the month field (middle three dashes) with the right outer knob, and select the proper

month (figure 4-187).
5. Move the flashing part of the cursor to the tens digit of the year field, and select the proper num­ber (figure 4-188).
6. Repeat step 5 for the ones digit of the year field.
7. Press F to start the KLX 135 using the newly entered date (figure 4-189).

To set the time on the SET 2 page:
1.Select the SET 2 page if it is not already selected.
2.Turn on the cursor and move it to the time zone field (figure 4-190).
3.Change the time zone with the right inner knob, if desired (figure 4-191). A listing of the time zones and their abbrevia­tions is contained in section 4.2, “Turn-on and Self Test”.
4.Move the cursor to the time field. The hours and minutes will appear in inverse video.
5.Select the correct hour (figure 4-192). Remember, the KLX135 uses 24 hour time. If it is 1:00 P.M. or later, add 12 hours (for example, 2:30 P.M. becomes 14:30).
6.Move the flashing part of the cursor to the tens of minutes, select the proper number (figure 4-193), then move on to the last digit and set it.
7.Press Fto start the clock running (figure 4-194). Note that the seconds will reset to zero when you do this.

4.14. THE OTHER (OTH) PAGES

4.14.1. DETERMINING THE STATUS OF THE GPS SIGNALS

The Other (OTH) 1 and OTH 2 pages may be viewed at any time to determine the status of the GPS receiver and the GPS satellites being received. This includes which satellites are being tracked, the satellites’ health, the signal-to-noise ratio for each of these satellites, the elevation of each satellite above the horizon, and the estimated position error.
The GPS receiver in the KLX 135 is capable of using signals from up to eight satellites to determine its position. A valid position may be determined using as few as four satellites alone or three satellites with a valid altitude input. However, four satellites alone or three satellites with an altitude input do not necessarily ensure that navigation can take place. The satellites must be positioned relative to your location such that sufficient “geometry” exists to determine an accurate position. the satellite constellation geometry is continually changing as each satellite, “rises”, travels across the sky, and eventualy “sets” relative to your position. The GPS satellites are not in geosynchronous orbits positioned over the same spot on earth at all times like some television communication satellites with which you may be familiar. Rather, the GPS satellites are in orbits that allow them to circle the earth about two times each day.
A representative OTH 1 page is shown in figure 4-195. The OTH 1 page displays the GPS receiver state and the system’s estimate of the posi­tion error expressed in nautical miles.
The GPS state is indicated on line 1.

In the initialization state the GPS receiver is in the process of initializing itself, collecting information such as the date, time, and last present position. Next, the receiver collects data from its own memory to determine which satellites should be visible. After completing the initialization process the receiver begins the acquisition process. During this time, the visible satellites are being acquired and data is obtained from them.
If the KLX 135 is not used for a period of six months or more, the satellite orbital data stored in the GPS receiver’s memory is too old to use. When this occurs, the receiver will enter the search the sky state to acquire the required data. This data, called almanac data, can be acquired by receiving just one satellite. A search the sky operation takes 20 minutes to complete.
The transition state indicates an adequate number of satellites for navigation has been acquired and is being tracked but no position data can yet be produced.
Normal navigation is indicated by a NAV, NAV A, or NAV D GPS state. NAV A indicates that the altitude input is being used in the position solution. NAV D indicates that besides calculation position, the receiver is collecting and storing in its memory additional data from the satellites (called ephemeris and almanac data).
Lines 3 and 4 of the OTH 1 page display the KLX 135’s estimated position error. The KLX 135’s position error depends upon such factors as the number of satellites being received, the strength of the GPS signals, and the geometry of the satellites presently being used for navigation.
Figures 4-196, 4-197 and 4-198 show a representative example of a set of OTH 2 pages. There will be three OTH 2 pages if more than six satellites are being received as in this example. The following information is displayed for each satellite on the OTH 2 pages:
The specific GPS satellites or “space vehicles” (SV) being received are displayed in the left column. Each satellite has its own identification number. A * symbol to the left of the satellite

4.14.2. VIEWING AND DELETING USER WAYPOINTS AND WAYPOINT REMARKS

The OTH 3 and OTH 4 pages list the user-defined waypoints and waypoint remarks, respectively, which are currently stored in the KLX 135’s memory.
4.14.2.1.The OTH 3 Page
An example of an OTH 3 page is shown in figure 4-199. All currently stored user-defined waypoints are listed in alphanumeric order. If the user-defined waypoint is the active waypoint, an arrow () follows the identifier. If the waypoint is used in one or more flight plans, then the number of the first flight plan in which it is used is displayed on the right side. If there are more than three user waypoints in storage, you can see the rest of the list by turning on the cursor (B) and turning the right outer knob to scroll through the list.

number of times the unit has been turned on. These values are reset to zero if the KLX 135’s non­volatile memory is cleared.

4.15. REMOTE MOUNTED ANNUNCIATORS

The KLX 135 has outputs capable of driving two remote annunciator lights: waypoint alert and message. Although these annunciators are optional, it is desirable to have them mounted in the pilot’s normal scan area so that these annunciators are easily seen. A typical annunciator is shown in figure 4-208; however, actual annunciation abbreviations and configurations may be different.
The remote waypoint alert annunciator is on whenever waypoint alerting is occurring. See sections 4.8.3, “Waypoint Alerting for Direct To Operation” and 4.10.2, “Turn Anticipation and Waypoint Alerting”.
The remote message annunciator is on whenever the message prompt is on. See section 4.5.

5. ADVANCED GPS OPERATION

5.1. CALCULATOR PAGES

The Calculator (CAL) pages are used for trip planning. They are con­venient both on the ground before you begin your flight, and in the air. The CAL 1 page performs distance, bearing, and time calcula­tions, and the CAL 2 page is for advisory fuel planning.
Data entered on any of the Calculator pages has ne effect on naviga­tion data provided on any Navigation (NAV) or Flight Plan (FPL) pages. You may perform trip calculations without disturbing ongoing navigation.
NOTE: The Calculator pages rely on pilot enterable inputs for groundspeed, fuel flow, and fuel reserve requirements. These pages do not utilize inputs from fuel flow or air data sensors.

5.1.1. THE CALCULATOR (CAL) 1 PAGE

The CAL 1 page allows you to do distance, bearing, and time calcula­tions that you might otherwise need a chart, ruler, and pocket calculator for. The KLX 135 will perform these calculations either from waypoint to waypoint (for in-flight calculations, your present position can be one of the waypoints), or for one of your flight plans (active or stored).
To calculate distance, bearing, and time from waypoint to waypoint:
1. From the CAL 1 page (figure 5-1), turn on the cursor (B). It will appear over a cyclic field that either displays Wpt (waypoint to waypoint) or Fpl (flight plan).
2. For this type of calculation, the cyclic field should display Wpt. Press E to toggle if this is not the case (figure 5-2).
3. Turn the right outer knob clockwise to move the cursor to the "from" waypoint in the upper right corner of the screen (figure 5-3).

4.Enter the desired identifier for the "from" waypoint and press F. You will be shown the waypoint page for the waypoint you entered. Press Fagain to approve.
NOTE: On either of the two waypoint fields on this page, you can select your present position. To do this, press E while the cursor is on the desired waypoint field. The results will only be displayed when your KLX 135 is receiving a valid position, or if you happen to be in the Take Home mode (see section 5.5).
5.With the cursor over the "to" waypoint, enter the desired identifier (figure 5-4) and press Ftwice. The distance in nautical miles and the bearing will be displayed on line 3.

5.1.2. THE CALCULATOR (CAL) 2 PAGE

The CAL 2 page is for calculating fuel requirements for a trip. To use these pages, you need to have a good idea what the typical fuel flow rate for your aircraft is. This information can often be found for given cruise power settings in a "performance" section of the operational handbook for the aircraft. The units for fuel are not specified on this page, but the units of time are always hours. This means that you can use gallons per hour, pounds per hour, kilograms per hour, etc. Like with the CAL 1 page, the fuel calculations can be done from waypoint to waypoint (including present position), or for one of your flight plans.
To calculate fuel requirements from waypoint to waypoint:
1.From the CAL 2 page, turn on the cursor (B). It will appear over a cyclic field that either displays Wpt(waypoint to waypoint) or Fpl (flight plan).
2.For this type of calculation, the cyclic field should display Wpt. Press Eto toggle if this is not the case.
3.Turn the right outer knob clockwise to move the cursor to the "from" waypoint in the upper right corner of the screen (figure 5-8).

5.2.CREATING USER-DEFINED WAYPOINTS

You may create and store up to 250 user-defined (also known as supplemental) waypoints. These waypoints will be very helpful to you. One major application is private airstrips, which are not included in the Jeppesen data base. They are also handy for points which you fly over frequently, and wish to navigate to. For example, a crop sprayer would want to store the locations of the fields he or she dusts often.
There are three ways to create a user-defined waypoint. If you happen to know the latitude and longitude of the point, that is one option. The waypoint can also be defined as a radial and distance from another waypoint. A third choice is just to store your present position under the identifier you have chosen.
NOTE: Whenever you are in a waypoint entry situation, such as a Direct To waypoint or flight plan, and you enter an identifier which is not in the data base, the KLX 135 will automatically start the user­defined waypoint creation process.
To delete a user-defined waypoint that is no longer needed, see
section 4.14.2, "Viewing and Deleting User Waypoints and Waypoint
Remarks".

5.2.1. CREATING A WAYPOINT AT YOUR PRESENT POSITION

Creating a waypoint at your present position is the simplest possible way to create a user-defined waypoint. This is nice for "remembering" a spot you are at. Let's suppose you're at a private strip that you want to name "VALLY"
