Just about every aircraft just short of GA aircraft have the ability to dump fuel. Even some cesnas have this ability. I sugest doing a little research before posting nonsense
Perhaps I am wrong. I was under the assumption that most modern aircraft can not dump fuel. The response of course was about the wish requesting that our AH aircraft should, which is essentially not possible to my knowledge, and I added that most modern aircraft still can not.
I did not consider rules of which aircraft are now considered. That was never mentioned. My bad.

I looked around to try and find a list of aircraft with this capability, but all I've found is that GA aircraft essentially cant, narrow body aircraft mostly can not, Widebody's mostly? can?, and military aircraft...I'm not certain of.
I apologize for the lack of research, I assumed, possibly wrongly that this is feature in an aircraft specific to its role, and thus mostly they do not have the ability due to cost, or their intentioned use.
Since you mentioned me not doing any research, and called me out on it, and you are correct (which I did only a little because I assumed it) You alluded to you have doing such, I really want to see what you came up with.
