These alphabetic codes are used on FAA and ICAO flight plan forms to aid flight service station (FSS) personnel in their handling of aircraft. On the FAA domestic flight plan form (FAA Form 7233-1) the equipment code is a single character placed in block 3 (Aircraft Type / Special Equipment) as a suffix to the aircraft type code. A single ...
There are 16,777,214 (2 24-2) unique ICAO 24-bit addresses (hex codes) available. [5] [6] The ICAO 24-bit address can be represented in three digital formats: hexadecimal, octal, and binary. These addresses are used to provide a unique identity normally allocated to an individual aircraft or registration. As an example, following is the ICAO 24 ...
ICAO: VFR standard squawk code when no other code has been assigned. [1] EASA countries: Code that pilot shall set when not receiving air traffic services, unless otherwise prescribed by the competent authority. [12] US: External ARTCC subset. (Block of discrete codes except that xx00 is used as a non-discrete code after all discrete codes are ...
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 ...
ICAO Doc 9830 defines A-SMGCS as follows: Advanced surface movement guidance and control system (A-SMGCS). A system providing routing, guidance and surveillance for the control of aircraft and vehicles in order to maintain the declared surface movement rate under all weather conditions within the aerodrome visibility operational level (AVOL) while maintaining the required level of safety.

These codes are defined by both the International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA). ICAO codes are published in ICAO Document 8643 Aircraft Type Designators [1] and are used by air traffic control and airline operations such as flight planning. While ICAO designators are used to ...
