What is the maximum headwind limit for automatic landing?

1. 20 knots

2. 25 knots

3. 30 knots

4. 35 knots

The correct answer is: 25 knots

The maximum headwind limit for automatic landings is indeed set at 25 knots. This figure is established based on the aircraft's handling characteristics and performance data, ensuring that even under relatively strong wind conditions, the automatic landing system can function reliably and safely. Exceeding this limit can compromise the performance of the autoland system, leading to potential safety risks during the landing phase. The specified limit allows for sufficient margin within which the system can operate effectively, accommodating the aerodynamic forces at play during an approach. It's essential for pilots and operators to be aware of this limit to ensure compliance with operational standards and to maintain safety during landing operations in varying weather conditions. In contrast, the other options represent wind limits that are typically considered too high for safe automatic landings, as they could introduce significant challenges in maintaining control and precision during the landing approach.
