not wanting to hichak (how do you spell that?) tread but is there anybody who knows how operaters do get charged??
either via flightplan or radio calls.
Is there anyone listing on the ground to all those radio calls at every strip??
Do you mean 'hijack'?
The simple version is the broadcasts are recorded, sorted and some poor soul writes down the callsigns. The regos are looked up and a bill is sent in the mail.
Also, If anyone is that worried about landing fees, maybe instead of saying nothing you could say something along the lines of 'XXX traffic, yellow Piper 15 miles to the north, inbound, 1500, XXX'.
