questions about jets
Hello, I'm studying towards my PPL with the view to become a jet airline pilot and I had a few questions that my instructor couldn't answer. Where does pressurised air come from when used in a jet aircraft cabin? And I'm being taught to use the ailerons and rudder pedals when turning, do you use the rudders in a jet, as I have read that you don't, if not then why not? And roughly how much does a 747 weigh? This is the aircraft type I'd look to fly. Thank you in advance, Peter
