In the long history of disinformation, rumour and waffle on PPRUNE this thread takes the biscuit.
Fact 1...There is no such thing a AEOp - they along with everyone else are WSOPs, with appropriate annotation.
Fact 2... There is no such thing as AEO or Nav. They are all WSOs with appropriate annotaion. Can't have a kipper was-AEO navigating a Herc around can we!
Fact 3...Any WSOp can apply for commision in whatever trade, or indeed profession for real aircrew, that he is suitably qualified for.
In essence nothing has changed.
