Skycop
Procedure at Shoreham is to enter the zone at 600' QNH below fixed wing circuit at 1100'.
This puts us at 400'agl over the downs just north of the airfield when re-joining.
Our unit policy is to fly as high as possible for the task in hand.
Glad I could clarify that for you.
We don't transit at low levels for the reason this thread is running!
