As a land owner you can operate off your own landing site for 28 days per year, this is generally 1 departure and arrival,
Surprised no one has commented on this! I always thought it was as many movements as you want provided you nkeep to the 28 days - much as someone else pointed out - you could have 28 fly ins with loads of a/c - a bit impractical, but I do know some guys that have just borrowed a field and organised BBQ's or even an overnight party with lots flying in!
