11. "I fly a design that is sometimes registered as a microlight on a permit and sometimes registered Class A with a higher MAUW. When I approach one of the many aerodromes that don't allow microlights to land, how will they know the registration status of my plane and disallow me?"
Interesting question. My guess would be the following:
"A decision not to accept microlights is not a legal matter, but an operational decision, made for some reason, by the airfield manager. Based on these operational conditions I guess an airfield manager will judge things on a case by case basis. But if problems arise, you can assume that the airfield manager will have access to G-INFO to settle disputes."
But I have no practical experience with this. Anybody wants to comment?
