Autopilot minimum for non-autoland ILS with CAT 1 FMA is which altitude?

• A. 100' AGL
• B. 120' AGL
• C. 160' AGL
• D. 180' AGL

Answer: (C)

On a CAT I ILS approach where the aircraft does not have autoland capability, the autopilot is allowed to follow the localizer and glideslope down to a fixed disengagement altitude. This altitude is 160 feet above the runway. The idea is to give the crew a clear hand‑fly window for the final phase of the landing; autopilot is not certified to perform the flare and touchdown automatically in non‑autoland aircraft, so you must manually take over by 160 ft AGL to complete the landing safely. The other options don’t align with this designated disengagement limit: 160 ft AGL is the established autopilot minimum for non‑autoland ILS CAT I.
