I don't necessarily think that it would be good to just put them on an OCF with the rest of the RAF crewmen. The RAF crewmen have an in-depth knowledge of the principles of restraint etc etc etc. Don't get me wrong, I'm not taking away anything from the AAC lads, but the level of trg the 2 services receive before OCU is quite different.
WG13 - The RN Cdo aircrewmen have been going through the same cse as the RAF crewmen since last year as JNCOs so I would suggest they are far more likely to be "the thin end of the wedge" than the AAC guys.
I would suggest that all rearcrew are given the same trg at DHFS (as the system's already bi-service, it's easier to make it tri-service) so there is a common output standard to OCF/OTP etc, especially if they are to work alongside current RAF SH crewmen on Ch/Me/Pu.
