What happened to filing a IFR flight plan inside controlled airspace?
I'm guessing that:
He didn't want to double his track miles by going out of his way to find CAS
It was impractical/impossible for his aircraft to climb to the base levels of most CAS in the UK airways system.
His aircraft wasn't equiped for IFR flight in Class A airspace.
He was flying IFR with an IMC rating, not an IR, so couldnt fly in class 'A' airspace.
Aside from those things, i've no idea why he wasn't on an IFR Flight Plan inside CAS.
