Thanks for the info so far. Sorry if I didn't explain myself properly. What I actually need is, when you are designing an airport, specifically the apron area, how much clearance space around, under and over must you allow for each Airbus A300 or A320. I've been asked to find out by an architect that I do research for and as I know little about aircraft except that I love to travel in them, I thought this forum would be a good place to start. The Airbus site itself is pretty hopeless for technical information of the kind I require.
