NutLoose,
We seem to go around the "Officers vs Men" buoy quite regularly, and the AAC's use of NCO pilots illustrates one aspect of that wider discussion.
a good Officer will always recognise where to go for detailed or specialist knowledge to support a broader decision
Flying an aircraft is the ultimate example of detailed or specialist knowledge. Assuming you can pass the 'pat your head and rub your tummy test", it's just another specialist course to pass. The fact that the RAF choose to combine that with its Officer assessment is probably historic from the nuke era, but the system seems to work. But just because it works doesn't mean that aircrew always need any great leadership abilities, and I would argue that CRM is not leadership, almost the opposite in fact. The AAC see the value of having a career option where relatively young and very incentivised NCO's can undertake highly specialized training in order to operate the Army's aircraft - without the need to commission everyone. That approach also seems to work very well for them.
Back to the thread (!) you would need to understand how Crewman Leaders would benefit from being commissioned to make a decision about wether it's a good idea or not. What day to day tasks require a leadership component as well as specialist knowledge. Maybe somebody knows.
