Great posts from airmen here, and some others

As a non-heavy pilot, I have really enjoyed the posts here and "meeting" the pilots and engineers. I also appreciate the comraderie and the warm welcome I have received, being a lite pilot and all...

Gee and roll rate trim and recovery

Thanks, Rudder, it's what I thot. Our simple FBW could be trimmed for a gee ( plus 3.5 gee and about minus 1 gee), which several guys did to have a zero gee hands-off stick for gaining energy. Roll...

Yaw versus roll

If I recall, we determined that the jet was not in a "deep stall" such as the Viper had or the T-tail jets. In other words, the cee gee and center of aero pressure was much like most...
