What is the minimum autopilot altitude for all approaches other than ILS/LPV?

• A. 100'
• B. 150'
• C. 250'
• D. 200'

Answer: (D)

Autopilot use on approaches is restricted by whether the approach provides vertical guidance. For approaches that do not offer vertical guidance (non-precision LNAV-type approaches), the autopilot may be kept in approach mode only down to 200 feet above the runway. Below that height, the crew should hand-fly or execute a go-around if needed. This safety margin exists because, without vertical guidance, the automatic system cannot reliably manage the final descent and flare in every situation, so human supervision is required as you approach the runway. When an approach does provide vertical guidance, like ILS or LPV, the aircraft can follow the published vertical path more closely, so the autopilot can remain engaged down to lower minima and assist through the final approach. The 200 feet limit applies specifically to those non-vertical-guidance approaches, which is why the minimum autopilot altitude for all approaches other than ILS/LPV is 200 feet.
