Transponder Set

A transponder set is a device used in aviation that helps identify and track aircraft. It consists of a transponder unit installed in the aircraft and a corresponding ground-based radar system.

The transponder unit is responsible for transmitting a unique identification code, known as a Mode S code, to air traffic control radar systems. This code helps air traffic controllers differentiate between different aircraft and track their movements accurately.

In addition to the identification code, transponders can also transmit other information such as altitude, speed, and flight number. This data is used by air traffic control to maintain safe separation between aircraft and to provide accurate and efficient air traffic management.

Transponder sets are an essential component of modern aviation and are required to be installed and operational in most aircraft operating in controlled airspace. They play a crucial role in ensuring the safety and efficiency of air travel.
