Yep, thought I would add that as a kid I was a horrible asthmatic, and still take proventive stuff and the occasional dose of ventolin. I called my examiner and he said go to a specialist. Specialist wrote a note that said I can fly and my doc said it would be fine, no faa approval or anything, got my class 1 that day.
A funny thing is that I have an odd depth perception prob( I have 1/3 normal depth perception, but like 20/15 vision) and was told by my eye doctor that I would never fly. Told that to my examiner and he said to tell her to f#ck herself. Since then I have earned a PPL, instrument, about to earn a commercial, and have flown formation
. Infact I have talked to 3 major airline pilots with the same condition, who even said that it was never even asked of them, and the only time they noticed was when the sim seemed a bit wierd. They did fine, just a slight bit of difference in the sim.
Moral of the story: the faa just wants to make sure that you do not have any conditions that endanger you or your passengers. In my case, my asthma is actually reduced at altitude, and I find it easier to breath. Never had an attack in an airplane, never had the vision part affect a flight, and really never thought twice about it.
Fly safe, and remember you inhaler just in case
BTW: According to an american capt I know, the asthma will not affect your chances of getting an airline job. Infact, he is partially color blind and got a waver, no prob. It is also partially illegal for the airline after they have accepted you to reject you for something like that, americans with disablilies act. Not to say it cannot happen, but from everyone that i have talked to, they say do not worry.
