What is the maximum tailwind component permitted for landing?

The maximum tailwind component permitted for landing is set to ensure safety and performance standards during the approach and landing phases of flight. A tailwind can significantly affect the aircraft's landing distance, the ground speed at which the aircraft touches down, and the overall handling characteristics during landing.

In the context of the CRJ550, the limitation of 10 knots for tailwind components is derived from operational guidelines and performance data to ensure that the aircraft has sufficient margin for a safe landing. This threshold helps to prevent issues related to increased stopping distance, especially as it could affect the aircraft's braking capabilities and overall control during touchdown.

While different aircraft may have various tailwind limitations, for the CRJ series, setting the maximum tailwind component at 10 knots strikes a balance between operational flexibility and safety, ensuring that pilots operate within parameters that align with the aircraft's performance specifications.
