Aircraft like 727, Dash-8, ERJ, CRJ, ATR all have integrated air stairs. Can some accommodation be made to play the passenger boarding sequence with such aircraft?
Docs for airliner (20+ passenger) say “failure to include … BOARDING_RAMP / JETWAY will not result in a blocker for the mission. It will mean that the whole sequence of boarding passengers, loading luggage, and unloading the catering truck just won’t be played” This would seem to exclude such airliners with airstairs from the sequence.
