Description

SECTION 1 DESCRIPTION

OVERVIEW

The GNS-XL Flight Management System is an integrated system designed to give the pilot centralized control for the navigation sensors, computer based flight planning, fuel management, and radio management. The GNS-XL has a full color flat panel LCD display, alpha-numeric and function keys, a Global Positioning Sensor (GPS), and a navigation data base. All these are housed in a panel/pedestal mounted Control Display Unit (CDU).

All aircraft interface requirements are accomplished through the GNS-XL. The system supports analog and digital inputs in any combination. Specific aircraft requirements are programmed into a Configuration Module. This module mounts directly to the rear connector, thus remaining in the aircraft. This allows hardware to be easily moved between aircraft types without changing system configuration. The following is a summary of the digital and analog interfaces:

Vertical Deviation

In addition to the GPS sensor, position information is accepted from up to eight navigation sensors, such as an optional VLF/Omega RPU, inertial position sensors, or VOR/DME radios. These navigation sensor inputs can be blended to form a single composite position. Accuracy of this composite position is enhanced by using the best

characteristics of each type of sensor. For example, an Inertial Reference System (IRS) has excellent short term characteristics while VLF/Omega has excellent long term stability. The internal GPS sensor has excellent overall characteristics and will usually be the dominant sensor during blending. However, when RAIM is available, the GPS sensor is the sole contributor to the composite position.

NOTE: RAIM (Receiver Autonomous Integrity Monitoring) is a quality factor used to determine the accuracy of the GPS position. It is an internal function of the GPS receiver and determines the accuracy of it’s navigation solution.

The navigation data base is updated on a 28-day cycle by way of a memory card. This card is inserted in a Personal Computer Memory Card International Association (PCMCIA) slot located under the lower portion of the alpha keyboard. This worldwide database contains over 50,000 waypoints, navaids and airports. It also contains altitudes at appropriate waypoints, SID, STAR, AIRWAY, and APPROACH procedures. In addition to this database, the memory can store up to 999 operator generated waypoints. Individual navigation points can be organized into 56 different stored flight plans, each containing up to 50 waypoints.

Due to the way the GNS-XL database is structured, waypoints must have unique identifiers. However, some duplicate ICAO identifiers exist for more than one waypoint. In these cases the waypoint identifiers are renamed in the database. Two naming conventions are used, one for four character identifiers and one for five character identifiers.

Four character waypoints keep the first four characters and the last two characters of the ICAO airport identifier as shown in the following example.

MA11 at KPRC becomes MA11RC in the database.

Five character waypoints keep the first five characters and add the last character of the ICAO airport identifier as shown in the following example.

MA27L at KOAK becomes MA27LK in the database.

Additional capabilities of the GNS-XL include direct navigation from present position to any waypoint, and data crossfill capability for dual installations. Trip Plan and Fuel Plan functions are also available. There is capability for creating a PSEUDO-VORTAC (selected

course) to any waypoint and establishing an offset parallel course. NAVs, COMMs, ADFs and transponders can be tuned through the system or by using the individual control heads.

GENERAL TERMS

FIELD: A line of information. CURSOR: Yellow rectangular box placed over a field to enter or

change the information in that field. The cursor is normally out of view unless brought into view by depressing the Line Select Keys on either side of the screen. When information is entered into a field and the ENT Key is depressed, the cursor will move to the next enterable field or disappear from the screen when the last field is entered. Blinking of a field indicates that the computer has not accepted the entry because of unreasonable or invalid information.

PAGE: Information is arranged in sections and subsections

much like chapters in a book. Individual screen displays are referred to as pages. Each section is selected by depressing the appropriate Display Selector Key located at the top of the keyboard. Each subsequent push of the key will select the next page of that section. A subsection page is selected by depressing the Line Select Key next to the topic desired, then depressing the ENT Key. The PRV or NXT Key can be used to move forward or backward through pages of a subsection. If the first page of a subsection is displayed, the BACK Key will exit the subsection.

WAYPOINT:A navigation point consisting of 1 to 6 alpha, numeric

characters that has a specific latitude and longitude.

NOTE: No database altitude constraints will be displayed at the MAP if the MAP is abeam or beyond the runway threshold . No altitude constraints are displayed on an approach if a PT is part of the approach procedure.

The following may appear in the waypoint altitude field:

• FL: Flight Level

• A: at or above

• B: at or below

• G: glide path (programmed Flight Path Angle)

NOTE: If an approach is programmed at the destination airport, and the MAP is the end of the runway, the altitude value displayed next to the MAP is approximately 50 feet above the runway threshold elevation. If the MAP is prior to the end of the runway and the approach is straight-in, the altitude displayed at the MAP is computed based on a line drawn from the FAF through the MAP to a point 50 feet above the runway threshold. The altitude may not be the MDA (Figure 2-

16). If no approach is programmed, the altitude value will be the airport elevation regardless of runway selection. The MAP altitude is shown in yellow.

The Waypoint VNAV offset is given in nautical miles where a negative (-)offset is prior to the waypoint (Figure 2-16, interpreted as "cross ten miles before RYMES at 3000 feet") and a positive offset is after the waypoint. If dashes appear in the altitude constraint field, NO altitude is programmed at that waypoint.

GPS TIME:

GPS time in hours, minutes and seconds. The advisory time is displayed when at least one satellite is being tracked, other-wise the time field displays dashes.

NOTE: GPS TIME may vary several seconds from GMT due to leap second input of UTC.

STATE: The GPS receiver state can be one of the following: Dashes: Idle or no mode data. INITIALIZE: The receiver is updated with initial position and time

information.

SKY SEARCH: No almanac is available. The system searches for

any satellite in the visible table based on the internal or external time, data, and position and then assigns channels in order received.

ACQUISITION: Constellation selection and channel assignments are

being done. Carrier and code lock are in progress.

TRANSITION: The receiver is transitioning from one state, such as

ACQUISITION, to another state, such as NAVIGA- TION.

NAVIGATION: The GPS receiver is in navigation mode and has at

least a two dimensional position fix.

DR: The system is in dead reckon mode. When the posi-

tion is valid and sufficient satellite measurements are unavailable, the receiver will continue to output valid position for a maximum of 30 seconds while using the last known velocity and track information. The position is invalid after 30 seconds.

MODE: Possible receiver modes are ENROUTE, OCEANIC/REMOTE, TER-

MINAL, and APPROACH. These modes are used to determine what

accuracy parameters should be used for a particular phase of flight.

ALT AIDED?:

Indicates the GPS receiver is using an externally supplied altitude input for position calculation.

The field also goes to dashes during a descent (digital systems only) when the aircraft is 200ft lower than the CRUISE ALT and the Preselect is set to a lower value. If the PRESEL is analog the altitude value will remain in the CRUISE ALT field. When the aircraft is within 200ft of the PRESEL ALT the CRUISE ALT changes again to the same value as the PRESEL ALT.

TRANS LEVEL:

Transition Level used to determine the altitude at which the system converts altitudes to Flight Levels. This field defaults to FL180 if the pilot does not enter a value. (Figure 2-46)

DEFAULT FPA:

The FPA defaults to the 3.0 unless it is manually entered. The default descent Flight Path Angle can be manually entered in degrees and tenths (0.1 to 6.0 range) (Figure 2-46). DEFAULT FPA is used to calculate #TOD to the first altitude constraint on the Active Flight Plan. However an FPA must be entered on the VNAV waypoint page to establish a PATH DESCENT and for Vert Dev or vertical deviations to be valid.

DIR CLOSET ARP 1/2

DIRECT TO CLOSEST AIRPORT: The Closest Airport

page is the last page in the DIRECT TO section. Up to nine airports are displayed, in order of their proximity to the aircraft, with the closest airport listed first. (Figure 2-

NOTE: Airports listed from the database on this page have runways 3000 ft long or greater and are hard surfaced.

WAYPOINT SECTION

WAYPOINT PAGES

Waypoints fall into four categories:

• Database generated

Page Display Definitions

• Pilot entered (personalized/ offset)

• Special

• Obsolete Waypoint Pages can be accessed from any FLIGHT PLAN, NAV,

, HOLD, INITIALIZATION, HEADING, or TRIP PLAN/FUEL PLAN Pages.

DATABASE WPT 1/1 (Page 1 of 1) Database Generated Waypoints

This page is accessed by typing in a waypoint identifier or by placing the cursor over a waypoint identifier and pressing ENT.

Database Generated Waypoints are automatically updated when accessed and cannot be modified by the operator. The four basic types of waypoints residing in the data base are navaids, airports, intersections and special waypoints.

DATABASE WPT 1/1

Non-Directional Beacons (NDBs)

NDBs stored in the internal database are listed in Jeppesen publications with a 2 or 3 letter identifier. To distinguish these NDBs from VHF NAVAIDS, you must add an "NB" suffix to the database identifier. Example: To access the Prince Rupert (PR) NDB, you must enter PRNB. (Figure 2-79)

Airports

International Civil Aviation Organization (ICAO) identifiers are used to access data in the database.

ICAO identifiers differ in some cases from those familiar to many pilots.

The following are guidelines to access information from the database: Except for a few hundred 3 or 4 letter/number airport identifiers in

Alaska, Canada and the Continental USA, all airport identifiers stored in the database have 4 letters.

Figure 2-79

In most cases, these identifiers begin with a letter that corresponds to the geographic area in which the airport is located. The ICAO code letter prefix for Continental USA airports is "K". Hawaii and Alaska identifiers begin with "P".

To access a 4 character identifier, use the IDENTIFIER found in the Jeppesen charts. For example, enter KSNA for Santa Ana. (Figure 2-80)

• If the airport shows a 3 letter IDENTIFIER, add the correct ICAO prefix letter. Example: NEW (New Orleans Lake Front) add a "K" prefix and enter KNEW (Figure 2-81).

• If the airport shows a 3 character (letters and numbers) IDENTIFIER, enter the identifier as printed. Example: 31J (Lake City, Florida) enter 31J. (Figure 2-

Airport Reference Points, Outer Markers, Runway Thresholds

Airport Reference Point (ARP) coordinates are always displayed in response to the airport identifier.

Figure 2-81

Figure 2-82

Outer markers and runway thresholds for which data is stored in the database are also displayed on the airport waypoint page (also known as airport continuation records page) and can be accessed by pressing the PRV or NXT Key or Line Select Keys. (Figure 2-83)

The selected outer marker or runway threshold will then be

Most intersection waypoint identifiers consist of 5 letters. However, 3, 4, and 5 letter and number combinations exist. To access these waypoints, simply enter the identifier from the Jeppesen chart. Example: WHALE intersection. (Figure 2-84)

SPECIAL DATABASE WAYPOINTS

PILOT ENTERED WPT (Personalized) Waypoint

The operator is responsible for generating the waypoint data and maintaining its accuracy.

WAYPOINT:

The alphanumeric designator selected by the pilot. Identifiers can consist of up to six characters, and can be composed of any of the characters on the keyboard. (Figure 2-85) However, the asterisk (*) and pound sign (#) have special functions.

Figure 2-84

POS:

Blank fields for entering the latitude and longitude of the waypoint. When initially accessed (waypoint not yet in memory) the coordinate fields are both dashed and covered by a double cursor. (Figure 2-85)

WPTS AVAILABLE: The number of waypoints available in memory after this waypoint is

defined. Maximum waypoint storage in non-volatile memory is 999. (Figure 2-85)
