<<The Land's End Transit corridor is a funny thing.>>
Funny peculiar. Which is what I was alluding to earlier before I got my ear bent by someone. This Toytown corridor has no status within Class G airspace, no special rules, no mandate, and IMHO is a joke. Somebody at Scillies must have dreamt this up and submitted it for inclusion in the UK IAIP along with his/her flight planning desires and it has slipped through the proof readers' net. There should be no compulsion nor co-ersion to operate over water in accordance with conditions dreamt up by such misguided individuals. The sooner it is withdrawn the better.
Englishal, I totally concur, FL60 and descend QFG if I want. Clearly your colleague has been duped by 'the corridor'. How many others, I wonder....
