AFT has not been considered for fast jet aircrew, despite the fact that both halves of it are owned by 22 Gp.
I don't know whether it's the same today, but certainly during 4FTS groundschool in Gnat / Hunter days, we covered world climatology. The relevance of 'horse latitudes' and 'willy-willies' to the operation of the Gnat always had me wondering....
Oceanic procedures and matters such as global HF communications are certainly taught and examined at ME OCUs / Trg Flts.
So, while it might be reasonable for some basic accreditation at 'wings' level, it is certainly
not reasonable for no further accreditation to be granted to vastly more experienced pilots.
