4.4 GTX 33 MODE S TRANSPONDER
The GTX 33 Mode S Transponder provides Mode A, Mode C, and Mode S interrogation and reply capabilities.
Selective addressing or Mode Select (Mode S) capability includes the following features:
• Level-2 reply data link capability (used to exchange information between aircraft and ATC facilities)
• Surveillance identifier capability
•
Flight ID (Flight Identification) reporting – The Mode S Transponder reports aircraft identification as either the
aircraft registration or a unique Flight ID.
• Altitude reporting
• Airborne status determination
• Transponder capability reporting
• Mode S Enhanced Surveillance (EHS) requirements
• Acquisition squitter – Acquisition squitter, or short squitter, is the transponder 24-bit identification address.
The transmission is sent periodically, regardless of the presence of interrogations. The purpose of acquisition
squitter is to enable Mode S ground stations and aircraft equipped with a Traffic Avoidance System (TAS) to
recognize the presence of Mode S-equipped aircraft for selective interrogation.
• Extended squitter – Transmits the Automatic Dependent Surveillance-Broadcast (ADS-B) position, velocity, and
heading information periodically without requiring an interrogation.
The Hazard Avoidance Section provides more details on traffic avoidance systems.
