What is the minimum autopilot altitude for a non-precision approach on the Global Express?

• A. 400 feet
• B. 50 feet
• C. 200 feet
• D. 800 feet

Answer: (A)

On a non-precision approach there’s no vertical guidance, so you descend to the published MDA and decide when to land based on visual references. You can use the autopilot to help you stay on the localizer and maintain a stable approach, but there’s a lower limit for how far the autopilot can be coupled during this type of approach. That limit is 400 feet above the runway. Staying autopilot-coupled down to 400 feet gives you a safety margin to verify the runway environment and be ready to land or execute a go-around if needed. Descending below that altitude without being prepared to land increases risk, while going higher than necessary would not take full advantage of the autoland assistance. So the minimum autopilot altitude for a non-precision approach on the Global Express is 400 feet.
