A lot of times they only charge you if you use the FBO, which is
everytime unless you're just doing a touch and go. Sometimes they
waive the fee if you buy a ton of gas (like literally a ton),
sometimes they only charge a fee if the aircraft is certified to
weigh anymore than a certain amount. It all really depends. In my
experience, the fee is very informal, and if you REALLY wanted to get
out of paying, you could probably just take off and I don't think
much would happen. Sometimes my company flies to large airports which
have landing fees, but we only ever go to the cargo apron and drop
off, so we never visit a FBO, and therefore never pay anything. I
know for a fact we flew into Toronto a few months ago, dropped off at
some cargo hangar, filed our flight plan back to KYIP, then took
right back off. Later I looked it up, and there is indeed a landing
fee there that we most certainly did not pay. All though they may
have called one of our dispatchers to collect the fee...

I thought a FBO was a private enterprise that operated on the premises
of the airport, not part of the airport mangement itself. What
exactly is the relationship of the FBO to the airport? Can't there be
multiple FBOs at an airport?

You don't have enough brains to think, moron.
