Everything here is from the references shown below, with a few comments in an alternate color.
FCC Control Law has transitioned to the alternate mode due to:
a. Flight . . . Continue
a. Airplane . . . Land as soon as practicable
b. If the Stab Pri Trim Fail (U) (caution) CAS message is displayed:
(1) Backup PITCH TRIM . . . Use (as required)
AOA limiting, stall protection and high speed protection features are unavailable. Low speed awareness and angle of attack may not be available.
If angle of attack information is available, stall warning (stick shaker) should activate at 0.85 AOA.
If unable to increase airspeed, descent may be required at higher altitudes and gross weights to maintain less than 0.65 AOA maximum.
a. Airspeed . . . 0.85-0.9M / .65 AOA maximum
a. Airspeed . . . 250-285 KCAS / .65 AOA maximum
WHEN OPERATING IN A DEGRADED FLIGHT CONTROL MODE, THERE ARE TWO FLIGHT CONTROL LAW GAINS. EXTENDING FLAPS TO AT LEAST 10° WHEN OPERATING AT AIRSPEEDS LESS THAN 200 KCAS WILL HELP PREVENT REDUCTION IN AIRPLANE CONTROLLABILITY.
a. Airspeed (Minimum) . . . 200 KCAS (flaps up)
b. FLAPS . . . As required
c. Airspeed (Minimum) . . . VREF +10 KCAS (flaps down)
d. Runway . . . Select runway based on minimum crosswind (less than 10 knots)
Landing distance should be based on VREF +10 KCAS to touchdown increased by a 1.25 factor for a shallow approach. Wheel fuse plug release may occur due to added landing speed under combinations of high field elevation, landing weight and OAT.
e. Landing Distance . . . Recalculate with a 1.25 factor
USE CAUTION DURING FLARE, OR IN GUSTY WIND CONDITIONS, DUE TO DECREASED FLIGHT CONTROL AUTHORITY.
If angle of attack information is available, maintaining VREF +10 minimum and below 0.65 AOA during approach and landing will ensure adequate maneuvering capability.
a. Approach . . . Fly shallow approach angle
b. Airspeed . . . Maintain VREF +10 KCAS
c. Landing . . . Minimize flare
