This was a modification of the ARI system where the differential tail deflection is faded out with increasing angle of attack.[^1] It also included increased roll damping, added a roll-rate feedback to reduce lateral damping, and counteracted adverse yaw with a lateral-stick-to-rudder gain of 2.6.[^1] This improves high AOA handling qualities.[^1] At approach and landing speeds a positive AOA bias of $8.96\degree$ was added to the AOA signal to produce a larger effective AOA.[^1] Mach scheduling didn’t vary the control system gains as landing was accomplished below M0.55.[^1] The pilots reported that the offset landing maneuver could be completed with their feet on the floor.[^1]
Roll channel:
Yaw control system:
From the strip charts below we can see that there is an immediate yaw rate response with well-damped yaw oscillations.[^1] The control inputs showed little sideslip.[^1]
