Aviation transponder interrogation modes

Index Aviation transponder interrogation modes

The aviation transponder interrogation modes are the standard formats of pulsed sequences from an interrogating Secondary Surveillance Radar (SSR) or similar Automatic Dependent Surveillance-Broadcast (ADS-B) system. [1]

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 registration

Every civil aircraft must be marked prominently on its exterior by an alphanumeric string, indicating its country of registration and its unique serial number.

Automatic dependent surveillance – broadcast

Automatic dependent surveillance — broadcast (ADS–B) is a surveillance technology in which an aircraft determines its position via satellite navigation and periodically broadcasts it, enabling it to be tracked.

Binary number

In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically 0 (zero) and 1 (one).

Call sign

In broadcasting and radio communications, a call sign (also known as a call name or call letters—and historically as a call signal—or abbreviated as a call) is a unique designation for a transmitter station.

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.

Gray code

The reflected binary code (RBC), also known just as reflected binary (RB) or Gray code after Frank Gray, is an ordering of the binary numeral system such that two successive values differ in only one bit (binary digit).

Secondary surveillance radar

Secondary surveillance radar (SSR)Secondary Surveillance Radar, Stevens M.C. Artech House, is a radar system used in air traffic control (ATC), that not only detects and measures the position of aircraft, i.e. bearing and distance, but also requests additional information from the aircraft itself such as its identity and altitude.

Traffic collision avoidance system

A traffic collision avoidance system or traffic alert and collision avoidance system (both abbreviated as TCAS, and pronounced "tee-kas") is an aircraft collision avoidance system designed to reduce the incidence of mid-air collisions between aircraft.
