Overview System Instruments Flight EIS CNS Interface GPS Navigation CNS Interface • 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. Pressing the IDENT Softkey initiates the ident function and reverts to the top-level softkeys. Transponder Reply Code Mode Status Transponder Data Box (Split-Screen) With a remote transponder configured, the #2 PFD Softkey becomes XPDR (if a navigation source is not selected) or XPDR/CRS (when the pilot can control the navigation course).
