When you land they are a bit hot on their restricted zone and you may need to be escorted to the terminal building.
On departure, you will need to go through the security zone in departures (empty pockets and such-like).
Lucy, this used to really bug me about Plymouth (my fixed wing a/c is based there and I commute in from my home most days into Plymouth in my helo).
The restricted zone should only be an issue if there is a dash 8 on the stand.
Seeing as I pay them so much in block landing fees and hangarage I now have my own security clearance and swipe card and even leave a car within the airport perimeter so the hassle factor is no longer an issue - a pain for visiting GA pilots though I agree.
Glad you enjoyed your visit.
