Must wear hat in Gusts...
I would never wear my hat on a walkaround.And the FOD argument makes complete sense.Au contrair,I certainly WOULD wear my hat for a walkaround on a windy day,if only for personal reasons.To keep my toupee in place! Two certain FOD's are a whole lot more hazardous than one 'potential' FOD.Of course we have a gust limitation for the headgear during the walkaround.And its in the Ops manual somewhere.That's where the chin straps come in.Only on walkarounds,where half the HWC plus gust component exeed the Ops manual limitation(nothing in the AFM in this regard),when one must wear one's headgear,to provide protection to his/her erm 'more sensitive' headwear should one make judicious use of the ol WW2 chin strap! Just remember to keep your head INTO the wind at all times during the walkaround.To prevent exceeding company 'wind limitation'...!!
