It could be a good test of feeling rational, if the premises were defined clearly enough. Presumably, most of us would not object morally to the idea of eating human meat if we were certain that it had been vat-grown, and would not object practically if we were reasonably sure that it is safe, but I’d guess that many of us would have a cached disgust response anyway, which, under these circumstances, would not be rational (because the disgust emotion would be stopping us from doing something that does not oppose our goals or values). I have to admit I’d probably fall into that group, those people who would not morally object but would feel disgusted anyway (especially as I’m used to feeling disgusted by all meat).
ISTM that the most likely evolutionary origin of disgust is a warning sign of a high risk of infection or poisoning, which would be present in the plane crash scenario so I wouldn’t even necessarily call it an irrational feeling.
Moreover not being content with someone merely acting rationally when being confronted with a powerful impulse towards a certain reaction that in this particular situation happens to be irrational, but going so far as requiring that they not even feel this impulse in that situation seems to be asking a bit much. One might say that displaying this attitude towards humans is rather irrational.
I think disgust is the normal reaction and doesn’t tell anything about rationality so you’d need to ask about the ethics of eating human meat.
