1.2 FRONT PANEL CONTROLS AND FUNCTIONS

Figure 1-1: Front Panel Controls and Functions

The KT 74 has the following front panel controls and functions:

• Display: See section 1.3.

• Mode Knob: See section 1.4.

• Push Buttons: See section 1.5.

• Functions: See section 1.6.

1.3 DISPLAY

Figure 1-2: Display

Operation D201308000036

Page 1-2 Rev 0 Dec 2013

KT 74 Pilot's Guide

The display shows the following indications:

• Active Mode: the Active Mode indicator shows the mode

that is currently set on the Mode Knob. See section 1.4.

• Pressure Altitude: The reported pressure altitude is

displayed as a Flight Level (FL), which is the pressure altitude in hundreds of feet. When non-standard atmospheric conditions apply, this may not match the altimeter indicated altitude, but will be correctly displayed by the Air Traffic Control (ATC) radar.

• Squawk Code: The current squawk code selected by the

Numeric Buttons. See Squawk Code Entry in section 1.5

• Flight ID: The aircraft call sign entered on your flight plan.

See Flight ID Entry in section 1.6

• IDENT Indicator: The IDENT Indicator shows when IDENT

mode is active. See section 1.5.

• Reply Indicator: The Reply Indicator is active when the

transponder replies to interrogations.

• Deviation Pointer: When altitude monitoring is in use, a

small deviation pointer appears adjacent to the altitude display on the transponder. See Altitude Monitor in section

1.6.

• Warning message: See section 1.7

• Fault Annunciation: See section 1.8.

Light Sensor

If connected to a lighting bus, the KT 74 will adjust the brightness of the front panel lighting based upon the lighting bus input. If no lighting bus input is detected, the KT 74 will automatically control the front panel lighting based on the ambient light sensor. The dim point for the Liquid Crystal Display (LCD) backlight illumination can be adjusted by using the configuration mode as described in section

1.9 of this guide.

interrogations.

ON

The transponder will respond to all interrogations, but altitude reporting is suppressed.

ALT

The transponder will respond to all interrogations.

When airborne, the transponder should always be set to ALT unless otherwise directed by Air Traffic Control. Aircraft installations that include a gear squat switch or other method of air/ground determination will automatically select surface reporting mode on landing or when taxiing. The mode indicator will read GND.

Figure 1-5: Functions

The different KT 74 functions are accessed using the FUNC button.

The functions displayed vary depending on whether the aircraft is airborne or is on the ground (squat switch or other method of air/ground determination installed) and has the GPS input enabled or not as shown in the following tables.

Each function is described in more detail below:

Flight Timer

Press the FUNC button once to display the Flight Timer. The Flight

Timer records the time for which the transponder has been powered

on and operating in flight mode – either ON or ALT.

D201308000036 Operation Rev 0 Dec 2013 Page-1-7

KT 74 Pilot's Guide

Stopwatch

Press the FUNC button twice to display the stopwatch. The stopwatch can be used as a convenient timer. Pressing ENT will reset and start the timer. Pressing ENT again will stop the timer.

Flight ID Entry

Press the FUNC button three times to display the Flight ID entry

screen. The edit the Flight ID using the numeric buttons. The lower portion of the display shows the alpha numeric characters selected through multiple presses of the numeric buttons. When the correct character is shown in the flight ID section of the screen, press the

ENT button to accept and advance to the next digit. The flight ID is terminated with a “space” character located on the 7 button. When ENT is pressed on the end space, the new Flight ID will replace the

previous value. If a button is not pressed for 7 seconds, the changes are ignored and the previous code restored.

The Flight ID should correspond to the aircraft call sign entered on your flight plan. If no flight plan is active, the aircraft registration should be used as your Flight ID. Use only letters and digits. If the Flight ID is less than 8 characters long, enter the “space” character

(7 button) to end it.

Altitude Monitor

Press the FUNC button four times to display the Altitude Monitor

enable screen. The Altitude Monitor activates an audio annunciator or annunciator light (depending on installation) when the aircraft pressure altitude differs from the selected altitude by more than 200

feet. Pressing ENT toggles the altitude monitor at the current

altitude.

When altitude monitoring is in use, a small deviation pointer appears

adjacent to the altitude display on the transponder.

Page 1-8 Rev 0 Dec 2013

KT 74 Pilot's Guide

ADS-B Monitor

Press the FUNC button five times to display the Altitude Monitor

screen The ADS-B Monitor is only available on installations that include an ADS-B position source. The ADS-B Monitor provides a display of the position information that is being transmitted in ADS-B position reports. This can provide confirmation that the correct information is being transmitted, particularly where the Global Positioning System (GPS) source is remote from the transponder.

In the event that valid position information is NOT available from the GPS, the latitude and longitude display will be replaced by dashes. If no valid latitude and longitude is shown, then ADS-B position information is NOT being transmitted.

Loss of ADS-B position information will also result in a WARNING message being displayed.

1.7 WARNING MESSAGES

If the transponder detects a problem, the screen will indicate

WARNING and a brief statement of the problem. Depending on the

nature of the problem, your transponder may not be replying to interrogations. Note the message on the screen and pass that information to your avionics maintenance organization. The WARNING message should clear when the event has cleared. Press

ENT to clear the message at any time; if the fault is still present the

message may reappear.

1.8 FAULT ANNUNCIATION

If the transponder detects an internal failure, the screen will indicate

FAULT and a brief statement of the problem. No replies will be made

to interrogations when a fault is detected.

Some FAULT indications can be recovered by switching the transponder off and back on again, although in all cases a FAULT code implies that there is a fault with the transponder or the installation. Note the FAULT message at the bottom of the screen and pass that information to your avionics maintenance organization.

1.9 CONFIGURATION MODE

The system is configured when it is first installed by your avionics installer. Configuration items include the Mode S aircraft address, the interface to the other aircraft systems, the aircraft category, and the pre-programmed values for VFR squawk code. To view or change these settings you must use Configuration Mode.

Do not use Configuration Mode in flight. Check

configuration.

To enter configuration mode, hold down the FUNC button while

switching on the transponder. Configuration items can be changed

using the numeric buttons (6 for down, 7 for up) and the ENT button to accept the selection. Pressing the 2 button will move back to the last menu item. Pressing FUNC advances to the next configuration

item. When configuration is complete; switch the transponder off. When it

is switched back on the transponder will use the new configuration.

1.10 LOW TEMPERATURE OPERATION

The KT 74 is certified to operate down to -25°C; however under cold operating conditions, the display update rate may be slowed but functional. The KT 74 incorporates an integral heating element in the front panel to automatically raise the temperature around the display. During cold operating conditions, a warm up period of 5 minutes minimum is suggested.
