Hi.Never had this before but my atc won't work unless I flip a radio/avionics on switch on each aircraft. Thatd=s fine on the basic a/c but with te AIrbus and other more complicated planes there is no switch to flick. Do I have to enable this generally somewhere else?ThanksAndy

Try resaving your default logon aircraft after you have turned the Avionics Switch ON.

Or create a hotket for it in Options > Assignments area. I use Ctrl+Shift+c. R-
