REPORT: VB-1611 ISSUED: JULY 12, 1995
9-76, 6 of 10 REVISED: JANUARY 2, 2001
SECTION 7 - DESCRIPTION AND OPERATION (continued)
Code Selection (continued)
Important Codes:
1200 - The VFR code for any altitude in the US (Refer to ICAO standards
elsewhere)
7000 - The VFR code commonly used in Europe (Refer to ICAO standards)
7500 - Hijack code (Aircraft is subject to unlawful interference)
7600 - Loss of communications
7700 - Emergency
7777 - Military interceptor operations (Never squawk this code)
0000 - Military use (Not enterable)
Care should be taken not to select the code 7500 and all codes in the 7600 -
7777 range, which trigger special indicators in automated facilities. Only the
code 7500 will be decoded as the hijack code. An aircraft’s transponder code
(when available) is utilized to enhance the tracking capabilities of the ATC
facility, therefore care should be taken when making routine code changes.
Keys for Other GTX 327 Functions
IDENT - Pressing the IDENT key activates the Special Position
Identification (SPI) Pulse for 18 seconds, identifying your
transponder return from others on the air traffic controller’s screen.
The word “IDENT” will appear in the upper left corner of the
display while the IDENT mode is active.
VFR - Sets the transponder code to the pre-programmed VFR code
selected in Configuration Mode (this is set to 1200 at the factory).
Pressing the VFR key again will restore the previous identification
code.
FUNC - Changes the page shown on the right side of the display.
Displayed data includes Pressure Altitude, Flight Time, Count Up
timer, Count Down timer, and may include Contrast and Display
Brightness, depending on configuration (as shown in the screens
below):
