What is the maximum tailwind component allowed for takeoff and landing for all aircraft?

The maximum tailwind component allowed for takeoff and landing for all aircraft is 10 knots. This limitation is based on safety considerations, as tailwinds can significantly affect an aircraft's performance during critical phases of flight. A tailwind increases the ground speed for takeoff and landing, which can lead to longer takeoff distances and potentially insufficient runway length for a safe stop or climb away from the runway. Additionally, excessive tailwind components can affect the aircraft's ability to maintain control during these maneuvers, especially in turbulent conditions.

By setting the limit at 10 knots, it ensures that pilots have enough margin to operate safely while still accounting for variations in aircraft performance under different weight and environmental conditions. Being aware of these limitations supports enhanced safety and operational efficiency during flight operations.
