As far as I'm aware, this is going to affect ALL NCA who were commissioned into any flying branch where their time served recieving NCA flying pay counted towards any increments in their officer flying pay scale, no matter the branch!
As far as back copies, all stores were told to return or destroy old pubs but I'm sure I'm going to be able to get hold of one, they must be basing their argument on a copy otherwise the case wouldn't stand.
