It's come to my attention that RN helis practice regularly on Dartmoor, so could anyone in the know help me on the following:
1. Is there a known 'best day' or busy patch
2. Is there a list in existence of 'approved' landing sites or is it impromptu
3. Like the Mach loop, are there any low flying routes on Dartmoor, with set directions and entrances or exits
4. If this is a one off, rare event, would there be any forewarning?
My aim is to get low level shots without driving 5 hours to the loop

Appreciate any help
