What would be the impact of exceeding the Vne speed?

Exceeding the Vne speed, which is the never-exceed speed, can lead to significant risks, including the potential for structural failure of the aircraft. This limit is established because flying above this speed increases stress on the aircraft's airframe and control surfaces. The forces acting on the structure during high-speed flight can exceed design limits, resulting in catastrophic failure or loss of control.

This risk is why pilots are trained to observe speed limitations rigorously. Vne is determined to ensure safe operation within the aircraft’s structural capabilities, and exceeding it can compromise safety. Adhering to the Vne helps maintain the integrity of the aircraft and ensures safe flying conditions.

In contrast, options like reduced climb rate, increased fuel consumption, or improved maneuverability are not primary concerns associated with surpassing Vne. These issues are more related to operational efficiency or performance characteristics, rather than the immediate danger posed by structural integrity when flying at dangerously high speeds.
