Autopilot minimum altitude for approach is which value?

• A. 100'
• B. 160'
• C. 400'
• D. 1000'

Answer: (B)

Autopilot minimum altitude on approach is the lowest altitude at which the autopilot is allowed to stay engaged and continue guiding you along the instrument approach. It’s set to give enough margin to manage the descent, configuration changes, and a safe handoff to landing or to execute a missed approach if needed.

In this case, 160 feet above ground level is the value used because it provides a practical balance: it allows the autopilot to control the approach to a stabilized point, yet leaves ample time and altitude for the pilot to complete the final configuration, confirm the runway environment, and take over for the landing or initiate a go-around if anything looks off. Lower values would reduce the margin needed to respond, while higher values would reduce the automation benefits during the approach.
