and give Avoidance IF REQUESTED
So class D most of the time, and in part class C when the customer want's it? Sounds dodgy from a legal point of view if you ask me!
Might as well make it class C, since it sounds like you need to treat it as such anyway......
I quite glad that the quoted pice does not figure in the rulebook I have to comply with!
Some airline crews (IFR) have had misgivings about the "lack of seperation" to VFR traffic (in TMA, medium level), but as far as I'm concerned: Bitch to the CAA and try to get more class C, othervise get yout eyes over the glareshield when you are given traffic info, and work the problem.
