What is the maximum takeoff and landing tailwind component when operating at high elevation airports?

1. 5 Knots

2. 10 Knots

3. 15 Knots

4. 20 Knots

The correct answer is: 10 Knots

The maximum takeoff and landing tailwind component when operating at high elevation airports is typically limited to 10 knots. High elevation environments present unique challenges for aircraft performance, including reduced engine efficiency and longer takeoff and landing distances due to thinner air. Consequently, regulations encourage maintaining a conservative tailwind limit to enhance safety and operational reliability. A tailwind can be more detrimental at these elevations, as it negatively affects the aircraft's ability to accelerate during takeoff and decelerate on landing. The 10 knots limit is a compromise that balances operational capability and safety, ensuring that pilots operate within parameters that consider these factors. This in-depth consideration helps pilots manage performance properly under varying altitude conditions.
