All major Airlines ask some pretty crazy questions but the info is out there for those that do the research. If I asked that question and the guy had no idea I'd not form a very good opinion of his desire to join my airline. It's not necessarily the question but whether you have bothered to do the research.
That's one aspect they're looking for.
And besides, it is important information to use in cold weather. I hope I never fly into Fairbanks with you in bad wx and fly into a hill.
cheers
