I gotta go with AZ33Z.

From reading all the stuff about the flight control laws, seems they wanted to have the pilot continue to hold some back stick versus just letting the plane continue on a Nz and attitude until touchdown. So you have to apply back stick to have a "normal" touch.

All the control laws and modes of the 'bus seem to get in the way, and it appears that the jet uses a RA altitude to go to the "flare mode". Don't like that, but never flew heavies or had that implementation.

I preferred the Viper implementaion that only used Nz ( biased for AoA) and pitch/body rates. Our aero gains were also used unless in a "standby gains" mode when the air data was FUBAR. The jet behaved like every other one we had flown. You could drive it on or flare a bit for an easier touch.

Still seems to this old fart that folks don't know when exactly they have direct control of the elevator unless in the pure "direct" mode. The gains and Nz inputs and such are there in all other modes and sub-modes and AP modes and on and on....
