What does Vh denote in terms of aircraft operation?

1. Maximum speed in level flight with maximum continuous power

2. Lift off speed

3. Maximum landing gear extended speed

4. Never exceed speed

The correct answer is: Maximum speed in level flight with maximum continuous power

The term Vh refers to the maximum speed in level flight with maximum continuous power. This is a critical performance metric for pilots to understand because it indicates the highest speed an aircraft can achieve while maintaining stable flight under full power conditions. Knowing this speed assists pilots in managing power settings and ensuring operational safety during various phases of flight, especially when climbing or flying at certain performance levels. Understanding Vh is essential for flight planning and operational safety, as flying significantly above this speed can lead to increased aerodynamic stress on the aircraft. It also helps pilots avoid situations where the aircraft might not respond adequately to control inputs, particularly during dynamic maneuvers or emergency situations, where maintaining control is crucial.
