Default Twp aviation questions
Hello,

a écrit dans
:
First, what qualifies an airport as an "international" airport? I've seen or
heard of some "international" airports that don't seem to be able to handle
worldwide flights. Maybe I'm wrong.
I belive that it is more a self-given qualification to get funds than a
a label given by an independent commission

Second, on many, if not most or all airliners, what is the small round
opening in the very tail that almost looks like an exhaust?
Well, it is an... exhaust
Of what is usually called an APU, Auxillary Power Unit. It's a turbine
engine, mostly electically started, which then uses fuel to run, and
drive an alternator. Thus, it will provide electical power for
preflight checks, without the help of a ground power unit.

Thanks.
Bye,
