What is the maximum speed for the external cargo hook doors when they are latched open?

The maximum speed for the external cargo hook doors when they are latched open is 200 KCAS. This specification is crucial for ensuring the safety and structural integrity of the aircraft during flight. Exceeding this speed with the doors open could lead to potential aerodynamic instability or damage to the cargo hook assembly. The limitation is set based on extensive testing and operational guidelines, which account for the airflow dynamics and control response when the doors are not in a closed position, helping to maintain optimal performance and safety during cargo operations. Thus, adhering to this speed restriction is essential for operations involving the external cargo hook system.
