Transponder (aeronautics)

Index Transponder (aeronautics)

A transponder (short for transmitter-responder and sometimes abbreviated to XPDR, XPNDR, TPDR or TP) is an electronic device that produces a response when it receives a radio-frequency interrogation. [1]

Aerobatics

Aerobatics (a portmanteau of aerial-acrobatics) is the practice of flying maneuvers involving aircraft attitudes that are not used in normal flight.

Air Defense Identification Zone

An Air Defense Identification Zone (ADIZ) is airspace over land or water in which the identification, location, and control of civil aircraft is performed in the interest of national security.

Air traffic control

Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through controlled airspace, and can provide advisory services to aircraft in non-controlled airspace.

Airborne collision avoidance system

An airborne collision avoidance system (ACAS, usually pronounced as ay-kas) operates independently of ground-based equipment and air traffic control in warning pilots of the presence of other aircraft that may present a threat of collision.

Aircraft hijacking

Aircraft hijacking (also air piracy or aircraft piracy, especially within the special aircraft jurisdiction of the United States and in the US state of Mississippi, and as skyjacking in some nations) is the unlawful seizure of an aircraft by an individual or a group.

Airspace

Airspace is the portion of the atmosphere controlled by a country above its territory, including its territorial waters or, more generally, any specific three-dimensional portion of the atmosphere.

Area control center

In air traffic control, an area control center (ACC), also known as a center (or in some cases, en-route, as opposed to TRACON control), is a facility responsible for controlling aircraft en route in a particular volume of airspace (a Flight Information Region) at high altitudes between airport approaches and departures.

Gillham code

Gillham code is a zero-padded 12-bit binary code using a parallel nine- to eleven-wire interface, the Gillham interface, that is used to transmit uncorrected barometric altitude between an encoding altimeter or analog air data computer and a digital transponder.
