I would just like to know from someone who knows about really big airports like O'Hare or Heathrow if it's allowed to land your toyplane there, or if they consider it to dangerous to join the traffic with a plane that has a topspeed as low as the stall speed of a 747. I guess it will cost you a fortune anyway, and nobody will do that, so it's useless to go planespotting at the runways of EHAM. So any input is welcome. Thanks!
In my experience it's different in the UK. No GA aircraft would consider landing at Heathrow or Gatwick except in an emergency. They are far too busy & airliners are generally queuing up to land. During the day there is a constant stream of aircraft on the approach spaced about 30 seconds apart. I've seen anything up to 8 aircraft on finals for Heathrow at any one moment throughout the day. The same applies to aircraft taking off. If they miss their slot they could wait several hours for another one.
I believe the regulations are that light aircraft must not land or take off until 4 minutes after a heavy jet due to the wake turbulence. This would obviously be impossible. The landing fees would also be prohibitive. There are smaller airfields close to most international airports that are used by light & GA aircraft.
