What is the fan speed limit for CRJ when the angle of bank is greater than 30 degrees and the speed is between 5 and 30 knots?

• A. Idle thrust only
• B. 75% N1
• C. No limitations
• D. 70% N1

Answer: (B)

The fan speed limit for the CRJ when the angle of bank exceeds 30 degrees and the speed is between 5 and 30 knots is set to 75% N1 for safety reasons. This limit is significant because higher angles of bank can result in increased aerodynamic loads on the aircraft. At these higher bank angles and low airspeeds, it's crucial to avoid thrust levels that could compromise engine performance or increase drag excessively. By restricting the engine thrust to 75% N1, the aircraft can maintain an adequate balance between power and control while also preventing situations that could lead to a stall or loss of control. This threshold ensures that the pilots have sufficient thrust to manage the aircraft safely during banked turns, particularly in conditions where precision handling is crucial.
