There is no sakana in lighting candles on board, it used to be allowed to smoke on board.
Foreign carriers like SQ and EK usually let F pax smoke in the lav (UNOFFICIALLY).
The issue is that a plane isn't a residence and since one doesnt reside there one cannot light there.
In turbulence you can hold on to a cigarette. Preventing the candles from falling or the menorah from getting knocked down may not be as simple.
As I said, the issue is whether there is anything to create the chiyuv, after all the mitzvah is ner ish ubaiso. But as I said, there is at least one shita that held you are michuyav to light in a similar situation. I don't remember who was quoted in the shiur I heard, but a quick search turns up the fact that the Maharsham paskened that one is mechuyav to light on a train. The psak appears to be even for coach type seating. Almost no one agrees to that psak, and you may be able to make chilukim between the train and other situations, but such a shita exists.
