What is the Vmcg speed for flaps 10?

Vmcg, or minimum control speed on the ground, is a critical speed for aircraft during takeoff, particularly in multi-engine airplanes. It is the minimum airspeed at which the aircraft can maintain controlled flight with one engine inoperative while on the ground. For an aircraft configured with flaps set to 10 degrees, the Vmcg is determined based on various factors, including aircraft weight, center of gravity, and configuration.

In the context of this question, the selection of 115 KIAS as the Vmcg speed for flaps 10 indicates that, at this speed, the aircraft can safely maintain directional control if one of the engines were to fail during the takeoff roll. Having an accurate Vmcg speed is essential for pilots, as it directly influences their decision-making during takeoff and their ability to handle engine failures. This knowledge helps ensure a safe takeoff profile and reduces risks associated with engine failure scenarios.

Understanding the significance of the Vmcg speed is crucial for effective flight operations, particularly in training and practical applications where engine-out scenarios must be managed within safe speed parameters.
