Hi All, I'm wondering about loading passengers in an extra and doing aerobatics. The following are weights for an Extra 330 LT. A full acro tank weighs about 100 lbs. typ. equipped empty weight 1.493 lbs / 677 kg MTOW normal category (+6/-3g) 2.095 lbs / 950 kg MTOW two-pilot acro (+8/-8g) 1.918 lbs / 870 kg MTOW single-pilot acro (+10/-10g) 1.808 lbs / 820 kg If the pilot weighed 210lbs (not exactly a random number ), that only leaves 115lbs for the front passenger (aprox). That means a 210 pilot is going to be flying in Normal Category almost all the time when carrying a passenger. The question is (for someone who has never flown aerobatics) what if any aerobatics can you do in Normal Category? It says +6/-3 g which seems like a lot to me, but that "Normal Category" vs "Acro category" has me thinking you can't do aerobatics at all. Thanks very much!
