Quite right pinger, the maintenance of the AAC operated Ac is of course carried out by the REME and they are responsible for one of the biggest splits in the AAC barring of course the aircrew, groundcrew divide. I disagree that the 64 is only two orders of magnitude removed from the Lx or Gz as it easily on a par with the Tornado, Harrier etc. Much greater methinks!
I can confirm that the REME do not have trained radar avionic greenies or as yet armourers for the comprehensive weapon suite and they will be reduced to that of "Black box changers" with much of the hands on maintenance being done by Westlands themselves who are building third line maintenance facilities at 'What-a-shame'. Much of the training (read all!) will be carried out in simulators and the Ac themselves will be subject to my earlier comments (re: Paddy Ashdown)
It will be interesting to see how the corps cope with their introduction as most of the current operating procedures cannot possibly cover the secret nature of most of the Ac systems, maybe I am wrong, but most of the avionics are highly classified which prevents most individuals from even looking into the cockpit (ie: groundcrew) and this problem had not even begun to be addressed when I left.
