Interesting!
To be completely cynical about this:
Primary radar from Waddo which is about 20 miles away. ILS turns in about 10 miles finals at, say 2000ft, so therefore about 30 miles from the radar head.
Base of cover?
Oh and isnt it between the 2 busiest pieces of unregulated airspace with fast and low military transits between the Vale of York AIAA and Lincs AIAA.
Procedural Control!!!!!!?
Don't you need a minimum number of movements to qualify for Class D zones?
Who did the safety management on that one?
I wouldn't touch it with yours!
