<![CDATA[Question about when to contact ATC for clearance if avionics are turned on after engine start in the Bonanza]]>I just completed my first flight in the Turbo Bonanza and when I heard the sound change when the seals inflate - mind blown...

One thing I am unsure about, not being a real pilot, is when you would contact ATC for clearance if the avionics don't go on until after engine start (per checklist).

Thanks for any real world advice.

That sounds like the procedure at a small GA airport? What about at a larger airport? Would the avionics ever be turned on for clearance and then off again before engine start?
