A while ago, a general smartening up of flying suits was ordered. They were to be of a standard appearance as decided by the sqn cdr, with flying badge or composite flying badge and name and no more than one badge per sleeve. Shirts worn underneath were to be of uniform sqn type.
The idea was to get away from the walking Christmas tree appearance of some aircrew; it worked well and there is no intrinsic reason why clean, smart, uniform sqn flying suits should not be treated as a proper service uniform which may be worn as laid down in service-wide rather than local regulations.
Personally I'd suggest rank insignia, uniform sqn name badge/flying badge, standard national flag on left shoulder and sqn badge on the other. Nothing else - no Red Flag, Top Gun, TLP, Leaping Wolf or other badges.
It's easy to understand why any stn cdr wouldn't want a bunch of scruffs on his patch - so if his/her aircrew stick to the rules then they'll be doing themselves a favour.
