I can fully understand the sense of injustice of those who fail in advanced training and see less able individuals swanning off down the ME route having been identified as weak at an early stage and streamed accordingly.
Don't stream everybody after tac weapons, make them all do the old basic course on Tucano. That way, everybody will have proved themselves capable in aerobatics, formation, IF and nav. It would be a set standard, enabling all pilots to come back and teach all of this as QFIs.
A few years from now, we'll have no set skill level to call upon. A bloke streamed ME after 50 hours of elementary instruction has no clue about turning upside down or whizzing around at low level at 4nm/min. His rotary peer simply doesn't 'do' upside down. Not their faults at all. So the only guys up for it are FJ mates and guaranteed there won't be enough to go around.
They've saved money in the short term with early streaming, but long-term it'll cost, and they've cut the old 'gold standard' of RAF wings. In the past, you had to prove yourself by passing basic. Now you just need to get through elementary.
Not the same from where I'm sitting.
