    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 ...

    Provides 4-digit octal unit code (set on ground for fighters, can be changed in flight by transport aircraft) [1] 3: A: Provides a 4-digit octal identification code for the aircraft, set in the cockpit but assigned by the air traffic controller. Mode 3/A is often combined with Mode C to provide altitude information as well. [2] C: Provides the ...

  4. Transponder (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Transponder_(aeronautics)

    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 ...

  5. Air traffic control radar beacon system - Wikipedia

    en.wikipedia.org/wiki/Air_traffic_control_radar...

    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 ...

    Mode 1: military only; provides 2-digit octal (6 bit) "mission code" that identifies the aircraft type or mission. [21] Mode 2: military only; provides 4-digit octal (12 bit) unit code or tail number. [22] Mode 3/A: military/civilian; provides a 4-digit octal (12 bit) identification code for the aircraft, assigned by the air traffic controller.

  8. Airfield traffic pattern - Wikipedia

    en.wikipedia.org/wiki/Airfield_traffic_pattern

    Fig. 4-3-1 from FAA AIM. Traffic patterns can be defined as left-hand or right-hand according to which way the turns in the pattern are performed. They are usually left-hand turns because most small airplanes are piloted from the left seat (or the senior pilot or pilot-in-command sits in the left seat), and so the pilot has better visibility ...

  9. NORDO - Wikipedia

    en.wikipedia.org/wiki/NORDO

    The term originates from the 5-character uppercase abbreviated notation "NORDO" displayed on controllers' radar scopes when an aircraft transmits the "radio failure" code on its transponder. An alternate explanation is that "NO RDO" was the standard note made on maintenance and equipment sheets used in military aviation, starting in the 1930s ...
