What is the maximum tailwind component allowed for reduced thrust takeoffs?

The maximum tailwind component allowed for reduced thrust takeoffs in the CRJ 200 is 5 knots. This limitation is in place to ensure adequate performance during the takeoff phase, particularly when utilizing reduced thrust settings.

When a tailwind is present during takeoff, it can affect the aircraft's ability to achieve the necessary takeoff speed and climb performance. Reduced thrust takeoffs already limit engine power to manage engine wear and fuel efficiency, so adding a tailwind further complicates the performance envelope. Limiting the tailwind to 5 knots helps ensure that the aircraft can safely meet required takeoff performance criteria, including reaching a safe altitude and speed before obstacles.

While a larger tailwind component might seem like it could be manageable under certain conditions, it increases the risk of insufficient performance, particularly in the event of an engine failure during the takeoff roll. Thus, aviation regulations and manufacturer guidelines dictate this limit to maintain safety and operational efficiency.
