HOw do you save a flight?? Do you use autosave or something else?? Thank u..

try ctrl-s for save. Ok, I'm kidding but then again you must be as well. This is now in my file of keepers along with "ctrl-e won't start my engines" . Sorry to be hard on you but you really have to try to find the basic answers and capabilities on your own.

When you taxing around the airport...make a quick reference of where the horizon meets the centre pillar/whatever.

Im afraid i dont quite understand what you mean. Would you mind explaining in a different way perhaps? :) Centre pillar?
