What to do when ATC asks you to switch to ‘ground mode’?
I did a search but didn’t find anything helpful.
Some airports/ATC have asked crew to switch their transponder to ‘ground mode’ after vacating the runway. On the A320 there is no specific switch that directly says ground mode.
What exactly is ATC asking for? Turning off Mode S? In which case selecting the transponder from “ON” to “AUTO” would be the correct selection?
A similar but separate question for the A320 - if you select transponder “ON” but ALT RPTG to “OFF” in your altitude still transmitted?
Thanks,
