Why is it important for pilots to know the speed associated with VNo?

Understanding the speed associated with VNo, or the maximum structural cruising speed, is crucial for pilots because it helps ensure that they do not exceed the structural limits of the aircraft. VNo is the upper limit of the green arc on the airspeed indicator, representing the maximum safe speed for flight in turbulent air.

Flying at or below this speed allows pilots to handle the aircraft safely while keeping within the limits that the aircraft was designed to withstand. Exceeding VNo can result in structural failure due to excessive aerodynamic loads, particularly in turbulent conditions. Therefore, knowing VNo aids pilots in maintaining the integrity of the aircraft and enhances overall flight safety.

The other options focus on various flight scenarios that may not directly correlate to the importance of VNo in maintaining structural integrity during flight.
