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

    In this example, the transponder code selected is 1200 for VFR flight (in North American airspace). The green IDENT button is marked "ID". A transponder (short for transmitter-responder [1] and sometimes abbreviated to XPDR, [2] XPNDR, [3] TPDR [4] or TP [5]) is an

  4. Aviation transponder interrogation modes - Wikipedia

    en.wikipedia.org/wiki/Aviation_transponder...

    When the transponder receives an interrogation request, it broadcasts the configured transponder code (or "squawk code"). This is referred to as "Mode 3A" or more commonly, Mode A. A separate type of response called "Ident" can be initiated from the airplane by pressing a button on the transponder control panel.

    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.

    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 ...

Some private-use and former airports may be included where notable, such as airports that were previously public-use, those with commercial enplanements recorded by the FAA or airports assigned an IATA airport code.

  9. Gillham code - Wikipedia

    en.wikipedia.org/wiki/Gillham_Code

    The transponder gets its altitude information from an encoding altimeter mounted behind the instrument panel that communicates via the Gillham code. Gillham code is a zero-padded 12-bit binary code using a parallel nine- [ 1 ] to eleven-wire interface , [ 2 ] the Gillham interface , that is used to transmit uncorrected barometric altitude ...
