What speed should not be exceeded when transitioning with doors during flight?

• A. 65 KIAS
• B. 70 KIAS
• C. 75 KIAS
• D. 80 KIAS

Answer: (B)

The appropriate speed not to be exceeded when transitioning with doors during flight is 70 KIAS. This limit is crucial for maintaining helicopter control and ensuring safety during operations involving the doors. Exceeding this speed could lead to increased aerodynamic loads on the aircraft and its components, potentially resulting in compromised control or structural integrity.

Operating within this speed limit allows for optimal handling characteristics, reducing the risk of adverse effects that could arise from open doors. It ensures that pilots can effectively manage transitions and maintain situational awareness, which is essential for safe flight operations. Therefore, adhering to the 70 KIAS limit ensures a balance between operational flexibility and safety during maneuvers involving the doors.
