Why does all you say apparently not apply, say, to Aylesbury Thame - a winch launching glider site and busy club with no powered facilities who nonetheless seem happy to welcome powered aircraft and publish procedures for them? Is there something wrong with the place?
Do they have planning restrictions related to numbers of powered aircraft movements per day and to the types of propellers and exhausts fitted to such aircraft? Planning was granted on the basis that we are a gliding club.
If you are not permitted to accept most powered aircraft you don't gear-up to handle them. That does not make us bad, unfriendly or awkward.
