Subject: Re: Weight and Balance
Not sure which regs the Grumman products were certified under=2C but I woul
d consult with FAR 23 or CAR 3 for how they define the aft limit. There is
probably some percentage forward of neutral stablity that they used in def
ining where the aft limit should be set. In the case of the F-16=2C I beli
eve at its aft limit it has 7% RELAXED static stability=2C but a flight con
trol system that constantly moves the tail surface to maintain the pointy e
nd forward. The B-2 was neutral to slightly unstable=2C with quad redundan
t flight control computers=2C and the F-22 is unstable with triplex compute
rs to keep in pointed in the right direction.
