Non-discrete mode A code reserved use in mode S radar/ADS-B environment where the aircraft identification will be used to correlate the flight plan instead of the mode A code. [1] US: Used exclusively by ADS-B aircraft to inhibit mode 3A transmission. [3] US: Non-discrete code assignments in accordance with FAA Order JO 7110.65, 5-2.
A discrete transponder code (often called a squawk code) is assigned by air traffic controllers to identify an aircraft uniquely in a flight information region (FIR). This allows easy identification of aircraft on radar. [6] [7] Codes are made of four octal digits; the dials on a transponder read from zero to seven, inclusive. Four octal digits ...
Distress signals are communicated by transmitting radio signals, displaying a visually observable item or illumination, or making a sound audible from a distance. A distress signal indicates that a person or group of people, watercraft , aircraft , or other vehicle is threatened by a serious or imminent danger and requires immediate assistance ...
The encoded number changes day-to-day. When the number is received and decoded in the aircraft transponder, a further cryptographic encoding is applied. If the result of that operation matches the value dialled into the IFF in the aircraft, the transponder replies with a Mode 3 response as before. If the values do not match, it does not respond.
The aircraft's transponder began to emit squawk 7500 — the international code for an aircraft hijacking — while flying north over Sudan. [5] When the pilot exited the cockpit to use the restroom, the co-pilot locked the cockpit door and continued to fly the aircraft. [6]
This information includes the call sign of the aircraft and/or the aircraft's permanent ICAO 24-bit address (which is represented for human interface purposes as six hexadecimal characters.) One of the hidden features of Mode S transponders is that they are backwards compatible; an aircraft equipped with a Mode S transponder can still be used ...
