What is the minimum autopilot altitude for ILS or LPV approaches?

• A. 200'
• B. 160'
• C. 100'
• D. 180'

Answer: (B)

Autopilot use on precision and approach-with-vertical-guidance procedures is allowed down to a fixed minimum altitude, after which the crew must take manual control. For ILS or LPV approaches, that minimum is 160 feet above the runway. This limit keeps the automation engaged long enough to maintain a stable approach and accurate flight path, while ensuring the crew has a clear, timely handover point to perform the landing and flare if needed. Going higher would unnecessarily force an early hand-fly segment, reducing the benefit of the approach automation; going lower would leave too little margin for a safe landing transition.
