A320 ATC Transponder 1/2 with change of control
Hey guys,
I remember on my initial type rating the training captains telling us to change the autopilot over when changing control. Fair enough.
They also said to change the ATC transponder to the associated side of the PF I.e 1 for CPT or 2 for FO. I can't remember for the life of me why this was, something to do with the altimeter being the one sent to ATC or TCAS or something. Any ideas?
