CinemaSins often points out as a sin movies that 'instantly make themselves unavailable for in-flight viewing due to plane-crash sequence' (e.g. Fight Club). Is this true; are there guidelines that major carriers follow for entertainment selection? Are depicted incidents with private craft (e.g. a Cessna) OK?
I'm not aware of entire movies being rejected, but scenes can get deleted. This happened with "Rain Man". From Uneasy Airlines Get Final Cut on 'Rain Man'
Passengers on at least 15 different airlines have been treated to Dustin Hoffman and Tom Cruise's Academy Award-winning road trip in "Rain Man" since the beginning of June, but the crucial scene that propels them on their highway odyssey in the first place has been edited right out of the picture.
"I think it's a key scene to the entire movie. That's why it's in there," Levinson told the Associated Press. "Without that scene, it comes down to this: You basically lose an enormous impact of the film. That scene tells you that they, mechanically, are forced to drive across country and, secondly, that Charlie can only push Raymond so far because he knows what will happen."
And at least a passenger organisation (not an airline organisation) has guidelines about this. From Curious cuts to in-flight films
The Airline Passenger Experience Association sets out a quick checklist of standards of what’s considered appropriate mid-air viewing: “No airline crash scenes or references to airline disasters; caution in depicting or referencing terrorism or; no nudity/sex scenes; no profanity; no racist comments or denigrating references to cultures, religions, or nationalities; caution in depicting violence, drug and physical abuse.
