My company policy in the airline is that we can’t push back until we have a FINAL load sheet with the correct weights for take off, landing & zero fuel which also includes the appropriate C of G %, it’s served me well all these years & I apply the same personal SOP to my Foxbat flying, except in the airlines we use standard weights e.g. 77kg for a male etc & in the Foxbat we use actual real time weights for everything.
The beauty of the Foxbat is that we are 590kg with full tanks, my wife as pax , 20 kg baggage in compartment plus backpack under her legs, weight & C of G NEVER an issue, I LOVE MY FOXBAT.
