Hi,
Yes CST brings up the commands ( I have spent hours reading the manual and knew this but didnt seem to work before). PF3 provides clearance, TGS, Takeoff Clearance, some other inflight commands until "radar services terminated". All frequencies and responses are handled by PF3 ATC using my CP.
Once climbing PF3 changes Hotkeys to inflight mode. I can use Hotkey2 to obtain destination ATIS. But at that point all comunication with PF3 ATC stops. #9 no beep/no response...#0 no beep/no response...#1 does not Activate Handoff but instead connects with FS ATC and my CP is asking for flight following. All further communication is with FS ATC. I have tried manually tuning to Tower and Approach frequencies to no avail. I am flying a Cessena 172 Skyhawk. Hpoe you can figure this out!
