When is Alpha Lock inhibition removed?

When is Alpha Lock inhibition removed?

• A. Inhibition is removed when AoA > 7.6° or speed < 154 kt
• B. Inhibition is removed only when landing gear is retracted
• C. Inhibition is removed when AoA < 7.6° or speed > 154 kt
• D. Inhibition is never removed

Answer: (C)

Alpha Lock inhibition is a safeguard that stays active when the aircraft is in a high angle of attack or low-speed situation, preventing certain protections from interfering during those unstable phases. Once the airplane moves back into a normal flight envelope, the inhibition is cleared. Specifically, the system releases Alpha Lock when the angle of attack falls below 7.6 degrees or the airspeed climbs above 154 knots. Those thresholds signal that the aircraft is no longer in the high-AoA/low-speed regime, so normal control logic can resume and protections can operate again. This isn’t tied to landing gear status, and the inhibition isn’t permanent—you would expect it to be removed as soon as you’re safely out of the high-AoA/low-speed condition.
