What is the consequence of exceeding the TH-73A's red radial airspeed indicator?

• A. Increased fuel consumption
• B. Improved lift performance
• C. Structural failure of the aircraft
• D. Decreased control responsiveness

Answer: (C)

Exceeding the red radial airspeed indicator in the TH-73A indicates that the aircraft has surpassed the maximum airspeed limitations, which can lead to structural failure. This limitation is established to ensure the aircraft remains within safe operating conditions. When the maximum airspeed is exceeded, the forces acting on the airframe can become excessive, potentially resulting in failure of critical structural components due to stress and strain.

Maintaining airspeed within the indicated limits is crucial for the safety and integrity of the aircraft. Exceeding these limits can compromise not only the structural integrity but also the overall safety of the flight, as it may impair the aircraft's ability to maneuver and respond appropriately. Ensuring flight operations remain within designated speed boundaries is essential for the longevity of the airframe and the safety of its occupants.
