What is the maximum altitude at which slats and flaps can be used on the CRJ 200?

The maximum altitude at which slats and flaps can be used on the CRJ 200 is 15,000 feet. This limitation is critical for ensuring the aerodynamic performance and structural integrity of the aircraft when using high lift devices like slats and flaps. At altitudes above this threshold, the air density decreases significantly, which can affect the effectiveness of these devices and the aircraft's overall performance.

It's important for pilots to adhere to this limitation to maintain control and safety during various phases of flight, particularly during takeoff and landing, when the aircraft needs maximum lift. Operating above 15,000 feet with slats and flaps extended could lead to performance issues, including increased drag and potential difficulties in handling the aircraft, particularly during critical phases of flight.

By understanding this limitation, flight crews can ensure they operate the aircraft within safe parameters and make informed decisions regarding altitude and flap/slat configurations during their operations.
