I'm afraid that there's the same no of secondary duties at Gannet as any other RN sqn (such is life). It's not true to say it's the only RN unit with a Lt Cdr WAFU as CO (what about 705, 750, 771, 849, 854, 857?)
Do those at HMS Gannet have to do the Duty Leading Hand duties? Duty Petty Officer? How about Officer of the Day? Air Officer of the Day? DLC(F) ?
705, 750 etc, etc are all Squadrons. The Boss of GSF is unique (in the FAA) in so much as he is the Commanding Officer of HMS Gannet.
Had a chat with the boys at Lee and Portland over the past couple of days and they can't wait to get the 92... they dont like the AW aircraft they currently fly.
