D Garmin G1000 Transponder Pilot's Guide 5-1 TRANSPONDER DESCRIPTION MODE S FEATURES The GTX 33 transponder is equipped with selective addressing or Mode Select (Mode S), capability. Mode S functions include the following features: · Level-2 reply data link capability (used to exchange information between aircraft and various ATC facilities) · Surveillance identifier capability · Flight ID reporting · Altitude reporting · Airborne status determination · Transponder capability reporting · Mode S Enhanced Surveillance (EHS) requirements · Acquisition squitter Flight ID Reporting ­ The G1000 transponder reports aircraft identification as either the aircraft registration or a FLT ID (Flight Identification). The system is configured for either option by an authorized Garmin service center. If configured for Flight ID entry, the pilot must enter the appropriate flight ID on the PFD. After the correct Flight ID is entered, the aircraft identification reported in response to ATC radar interrogations is properly correlated with the associated call sign for voice communication. When a Flight ID contains a space, the system automatically removes it upon completion of Flight ID entry. In this configuration, the transponder then reports the aircraft registration number to ATC. 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. If Altitude mode is selected, a green ALT indication is displayed in the mode field of the Transponder Status bar, and all transponder replies requesting altitude information are provided with pressure altitude information. CODE SELECTION Entering a Code A total of 4, 096 discrete identification codes can be selected with the Code Selection softkeys. Press the XPDR softkey to display the transponder Mode Selection softkeys. Press the CODE softkey to display the transponder Code Selection softkeys, for digit entry. When entering the code, the next key in sequence must be pressed within 10 seconds, or the entry is cancelled and restored to the previous code.
