    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.

  3. Transponder (aeronautics) - Wikipedia

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

    When ground-based radar equipment [9] receives the IDENT bit, it results in the aircraft's blip "blossoming" on the radar scope. This is often used by the controller to locate the aircraft amongst others by requesting the ident function from the pilot, e.g., "Cessna 123AB, squawk 0363 and ident". [6] [7]

  4. Distress signal - Wikipedia

    en.wikipedia.org/wiki/Distress_signal

    The civilian aircraft frequency for voice distress alerting is 121.5 MHz. Military aircraft use 243 MHz (which is a harmonic of 121.5 MHz, and therefore civilian beacons transmit on this frequency as well). Aircraft can also signal an emergency by setting one of several special transponder codes, such as 7700.

    A voice warning system is a system designed to alert the crew of an aircraft to imminent safety hazards. It is often known as a Bitchin' Betty, a slang term used by some pilots and aircrew and submariners (mainly North American). The enunciating voice, in at least some aircraft systems, may be either male or female.

  7. Minimum safe altitude warning - Wikipedia

    en.wikipedia.org/wiki/Minimum_Safe_Altitude_Warning

    Minimum safe altitude warning (MSAW) is an automated warning system for air traffic controllers (ATCO). It is a ground-based safety net intended to warn the controller about increased risk of controlled flight into terrain accidents by generating, in a timely manner, an alert of aircraft proximity to terrain or obstacles.

    en.wikipedia.org/wiki/Airborne_wind_shear...

    The airborne wind shear detection and alert system, fitted in an aircraft, detects and alerts the pilot both visually and aurally of a wind shear condition. A reactive wind shear detection system is activated by the aircraft flying into an area with a wind shear condition of sufficient force to pose a hazard to the aircraft.
