Defuelling
Once upon a time there was a CAO detailing fueling and defueling, or so I thought. Now I can only find a CAO on fueling with very limited info on defueling, specifically defueling avgas.
Does anyone know:
Is defueling now considered a fueling operation or am I missing something in my regulations search? Under what circumstances can I remove quantities of fuel other than small samples from fuel tanks on an aircraft, say to meet weight and balance requirements?
