Yep, being at an RAF Flying Club, we always outbrief to ensure that we have checked everything (Notams, FOD hazards, ATIS, Ops, ATC, Royal Flights, Alternate landing, wx, Tech log, Auth sheets etc etc)
Bit formal yes, but its got me into good habits anyway. Must say though, i don't always see the Civvy trained members outbriefing!
Dress.... grow bags, military boots and leather gloves...Personally I wouldn't fly without 'em.
