I occasionally fly student x-countries there as we use it as a point on the PPL QXC route.
Best practice is to call up at least 10 mins before ETA .
They provide FIS/LARS on the approach service.
No real problems, but you may have to fit in round IFR/commercial traffic.
Hi-vis jackets are required.
You may have to go round to the terminal to book-in and pay your landing fee.
Booking out can be done on the phone at the GA office.
