What is the maximum ambient temperature for takeoff and landing on the CRJ 900?

The maximum ambient temperature for takeoff and landing on the CRJ 900 is indeed 50°C. This limit is established to ensure safe operation and optimal performance of the aircraft systems and engines under high-temperature conditions. When the temperature exceeds this limit, the aircraft may experience reduced engine performance, which affects climb rates, takeoff roll distances, and overall safety margins.

Understanding this limitation is essential for flight crews, as it impacts flight planning and operational decisions. This performance factor is crucial, particularly during hot weather, where the aircraft's ability to maintain safe performance standards can be compromised.
