What is the required minimum for ILS or LPV autopilot operations?

For ILS (Instrument Landing System) or LPV (Localizer Performance with Vertical guidance) autopilot operations, the minimum altitude for autopilot operations is 200 feet AGL (Above Ground Level). This requirement ensures that pilots have sufficient visual reference and control of the aircraft during the critical phases of approach and landing.

At or below 200 feet AGL, the pilot must be prepared to take manual control of the aircraft, especially in the event of an autopilot failure or lack of adequate visual references. This altitude is established to maintain safety and provide pilots with the ability to effectively react to any unexpected situations during the landing phase. The higher minimums offered by the other choices would not align with the operational standards for safe and effective ILS or LPV approaches established in aviation regulations.
