I'm not totally against CDFA, HC, I believe it is one of those things that does no harm, but I think doesn't necessarily do any good. Particularly for helicopters as opposed to FW.
I'm off now, but if people are still interested in 2 weeks, I will elaborate then.
The argument was 30 - 40% of CFIT accidents were from NPAs. This is true for FW but, while I'm away, let everyone find a helicopter CFIT from NPA to discuss. This one, yes, but that's not 30%. Be careful not to include visual manoeuvring following an NPA.
