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)
0021 The VFR code commonly used in Germany (default is set to 0021 at time of
installation)
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)
Avoid selecting code 7500 and all codes in the 7600-7777 range. These trigger special indicators
in automated facilities. Only the code 7500 will be decoded as the hijack code. An aircraft’s
transponder code (if available) is utilized to enhance the tracking capabilities of the ATC facility,
therefore care should be taken when making routine code changes.
