poor roll coordination for large lateral inputs, pitch coupling, and/or sluggish pitch response can be
expected. Due to the higher reliability of AHRS over previous rate and acceleration sensors, a four
channel failure is highly unlikely. However, simulator evaluation has shown that a complete four
channel AHRS failure (no rate and acceleration inputs to FCCs) is controllable for most of the flight
envelope with the flaps in AUTO. Refer to figure 11-1 for AHRS channel failure indications and effects.
AHRS failure modes have not been flight tested. With a four channel
AHRS failure, the aircraft is not controllable with the flaps in HALF or
FULL. At altitudes above 25,000 feet, loss of control occurs below 0.92
Mach. For loss of AHRS above 25,000 feet, maintain airspeed above 0.92
Mach while descending.
With a four channel failure at altitudes below 20,000 feet, flying qualities are best between 190 to 210
KCAS. The worst flying qualities are between 270 to 370 KCAS. Flying qualities do improve above 370
KCAS, with a further improvement at supersonic speeds. Execute a straight-in on-speed approach with
flaps in AUTO, and limit angle of bank to 20°. Pitch and directional damping will be very low and roll
coordination weak. If not positioned for landing by in the middle to in close, a wave-off and go-around
should be executed. A clean, lightly loaded aircraft exhibits the best flying qualities. Flying qualities
are not affected by CG locations, and the aircraft can be landed to the aft CG limit. An arrested landing
should be made if airspeed permits. Avoid stabilator braking.
