5.5.4.9.1.1 ICAO Address
Enter the aircraft assigned ICAO address code, eight octal digits. This code can be found in either of the
following locations:
• The aircraft registration certificate
• The N-number inquiry page of
http://registry.faa.gov/aircraftinquiry/
.
NOTE
Correct entry of the assigned aircraft ICAO address in the GDL 88 is critical.
5.5.4.9.1.2 Aircraft Call Sign
Enter the US registration number (N-number). Valid characters are A-Z, 0-9, and trailing space.
5.5.4.9.1.3 Mode 3/A VFR Code
Enter the VFR transponder code. This field has a range of 0000-7777.
This setting is used for the UAT anonymous mode feature (if enabled), where the transponder must be
tuned to this code before the GDL 88 is capable of transmitting a temporary address and a call sign of
“VFR”.
NOTE
Enter only valid VFR codes. The code must match the VFR code configured on the
transponder. This is typically 1200 for US-registered aircraft.
