My apologies for being a grumpy pr1ck at times.....If you knew me you would know that I am not like that by nature.
However I do stand by my point that I think it is a serious deficiency in your basic knowledge as a professional pilot, and wonder how it could happen.
Maybe I should have just said that, maybe I was in shock....
But if you asked the guy flying you and your family on the 747 what the flaps do and he says "I really dunno, it just helps you land and take off" you'd have a few concerns wouldn't you?
