Autopilot must be disengaged by no lower than how many feet AGL?

• A. 50 feet
• B. 75 feet
• C. 100 feet
• D. 150 feet

Answer: (C)

Disengaging the autopilot by a set altitude ensures the pilot has adequate time and control authority to complete the final phase of the approach and perform a safe landing if needed. For the P-8A, the limit is 100 feet AGL, which gives a stable, hands-on transition from automated flight to manual control in the critical last moments of the approach. This boundary protects against too little reaction time if something goes wrong near the runway, and it avoids unnecessarily restricting automation higher up the approach path. In practice, you maintain autopilot operation down to about 100 feet AGL so you can verify the configuration and flight path, then take manual control for the flare and touchdown. Lowering the limit below this would shrink the window for corrective action, while raising it would unnecessarily limit automation during a stabilized approach.
