So.. if the ATIS says "contact ground/clearance" prior to engine start,
does that constitute instruction from "air traffic control" which must
be complied with except in an emergency?

and is not obtaining (and complying with any instructions on) the ATIS
failure to obtain all relevant information regarding the proposed flight?

Can you reconcile these concepts (loosely paraphrased from the part 91
rules regarding ops) with what you are saying that there is "no
requirement to call ground prior to engine start" when in some
circumstances there appears to be?

I think what you are forgetting is that the AIM is not regulatory. From
the looks of it, it is as if you're expecting to get a violation if you
start your engine prior to calling ground. That just won't happen.

This thread has gotten out of hand. The bottom line is that if you
start your engine, then get your clearance, then call ground, it may
end up wasting your time with the engine running if there are delays.
But, no matter what, you will never get in "trouble" for starting your
engine prior to getting the clearance, or talking to ground.



Or, in other words, there's no requirement to call ground prior to engine
start.
