Surely, if there is a surplus of qualified aircrew, the RAF should immediately slap a ban on pilot recruitment until it is sorted out.
Most AEOp and Navs could easily be trained up as pilots particularly for the non pointly fleets. Most would have the aptitude and the need to pass Crandits should not be used as a way to delay and block applicants who have already demonstrated their skils in the airborne environment.
Fast track them and ensure that pilot is open to all as a realistic option.
These are exceptional times Its time to tear up the old rule book and concentrate on getting well qualified dedicated professionals into appropriate alternative positions, quickly and cost effectively without wasting yet more taxpayer's money. These people are already there, the taxpayer has invested a lot in them. Retrain them! Flying a modern multi engined aircraft is just not that difficult.
If the RAF is talking redundancy, then rule number one is to first seek suitable alternative positions. Until that is done, recruitment should stop.
