What is the minimum ambient temperature for takeoff on the CRJ 900?

• A. -50°C
• B. -40°C
• C. -30°C
• D. -20°C

Answer: (B)

The minimum ambient temperature for takeoff on the CRJ 900 is -40°C. This limitation is crucial for maintaining safe operational parameters of the aircraft. Operating at or above this temperature ensures that essential aircraft systems, including engine performance, fuel flow characteristics, and wing de-icing systems, function properly. Temperatures lower than this can affect engine starting, increase the risk of icing, and lead to performance issues that could compromise safety during takeoff and initial climb. Knowing this minimum temperature is essential for pilots and flight operations to ensure that they do not exceed limitations that could adversely affect the aircraft's performance and safety.
