Which altitude thresholds are associated with autopilot limitations just above the ground during landing?

1. 1000 Feet AGL

2. 200 Feet AGL

3. 300 Feet AGL

4. 400 Feet AGL

The correct answer is: 200 Feet AGL

The altitude threshold of 200 feet AGL (Above Ground Level) is critical when discussing autopilot limitations during the landing phase of flight. At this altitude, pilots are typically transitioning from the automation of the aircraft to manual control. The 200 feet AGL threshold is significant because many autopilot systems are designed to disengage automatically when the aircraft descends below this altitude. This automatic disengagement is intended to ensure that pilots can regain manual control of the aircraft, which is vital for a safe landing, particularly in the final moments when visual cues from the runway become more prominent. This altitude is a standard reference point where the decision-making process shifts from reliance on automation to the pilot's skills. A specific focus on this altitude threshold aligns with regulations and safety practices in aviation, underscoring its importance in both training and operational protocols. Other altitudes mentioned, such as 1000 feet, 300 feet, and 400 feet AGL, do not reflect the critical operational limits that define the transition from autopilot to manual flying during the landing phase.
