N - you might be in for a shock when Harmony guidelines are "tri-serviced"...
Indeed Wings and F (and everyone else in the Air Dept) can be not CHF, but on the basis the Stovies can't do it, you're reducing your potential pool to the Baggers and Pingers. The Lynx boys traditionally haven't done it because they've never worked from a big deck.
The wider point is about embarked Maritime Aviation - every argument made about CHF could equally be made about the Baggers (and possibly the 771 Cabs and Grey Merlin). At some point a decision needs to be made - if you fly from the sea, you need to work, properly, from the sea. Light Blue, Dark Blue, Green, at the end of the day I don't care, you just need to lift when I instruct you and keep to the FlyPro....
