Airway Crossing
I'm planning an IFR flight off airways, from Enstone direct Isles of Scilly.
The question of airway crossing comes to mind at Bridgewater Bay. I'll be cruising at FL40, seeing as the base of N864 starts at FL55, is there a requirement for me to fly at right angles until clear of the airway?
I'm not in Class A at that height, or within the airway.
My other plan is from Enstone direct Swansea direct Isles of Scilly.
Now is there any requirement for me to cross any airways so long as I stay beneath them? In this case it is FL75, and FL165. So according to the quadrantal rule, I'll be at FL60. And clear of problems?
Thanks
