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 ...

The transponder has a small required set of controls and is simple to operate. It has a method to enter the four-digit transponder code, also known as a beacon code or squawk code, and a control to transmit an ident, which is done at the controller's request (see SPI pulse below). Transponders typically have 4 operating modes: Off, Standby, On ...
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 distinguish between aircraft types and variants that have different performance characteristics affecting ATC, the codes do not differentiate between ...
On January 14, 2012, the vSTARS ATC client was approved for use on the VATSIM network. [43] Also created by Ross Carlson, the client aims to replicate the real-world STARS system used in many US TRACON facilities. On February 27, 2016, the vERAM ATC client was approved for use on the VATSIM network. [44]
TIS-B is broadcast to aircraft using both the 1090 MHz extended squitter (1090 ES) and the universal access transceiver (UAT) band of Automatic Dependent Surveillance–Broadcast (ADS-B). [3] Currently the service mainly benefits general aviation (GA) aircraft equipped with ADS-B "in" hardware by providing a traffic information relay to a ...
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 ...
