Holding?
I am on an AEF where we have a holding pilot aged 27 awaiting a Hawk Course.
One of the pilots he did basic with got axed with the 170 pilots and is now a qualified Airbus co pilot at Manchester. I have flown with him so...
Depending on how much holding one gets on the multi route I would suggest you bin the RAF right now and get on a CTC course this year.
I am sure a multi tour would be fun but hanging around waiting for the RAF to train you is a serious impediment to your future prospects.
The holding pilot may get his Typhoon moment but his mate will be a training Captain by the time he bails out into civvy street.
