4.3 REMOTE TRANSPONDER INTERFACE
(OPTIONAL)
NOTE:
If the aircraft is configured with a remote transponder rudder and
aileron trim indicators are not available on the PFD. All trim gauges are
available from the ENG page.
The G3X is capable of interfacing with several remote transponders providing
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
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 the 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.
When configured the transponder interface is displayed on three levels of softkeys
on the PFD: Top-level, Mode Selection, and Code Selection. When the top-level XPDR
Softkey is pressed, the associated transponder softkeys appear: IDENT, CODE, and
MODE.
When the CODE Softkey is pressed, the pilot can enter the desired code using the
FMS Joystick.
