gums The YF-16 could be flown with a "conventional" forward c.g., but allowing it to move aft provided a dramatic increase in several parameters
how much is the range of moving aft the CG for the YF-16 ? 40%?? 45%? or more ?
my raw calculation for an A330 with 205t is that the change of CG is abaut 0.7m if you transfere 4,8t from trimtank ca. 31m(?) foreward to centertank (31*4,8/205=0,7)
100% of the profile may be around 6,6m ,and if the trimtank was full (?)
the max cange in CG is 10,6% (0,7*100/6,6=10,6)
given CG 37% the max forward CG in that case might reach 26,4%
p.s. if 10 Pax move 40m the change of CG is not nothing, it is ca. 2,2%,
