What is the term used for the amount of power needed to produce thrust required?

The term for the amount of power needed to produce the required thrust is referred to as "Power Required." This concept relates to the relationship between thrust and the power needed from the aircraft's engines to generate that thrust under specific operating conditions, such as speed and altitude.

In aerodynamics and aircraft performance discussions, understanding the power required helps determine how efficiently an aircraft can operate during various phases of flight, such as takeoff, climb, cruise, and descent. Pilots need to make calculations based on power required to ensure they have adequate thrust for safe operations, particularly in varying flight conditions.

This term emphasizes the necessity of aligning the engine's capabilities with the demands of flight, allowing for effective planning and performance management. Each of the other terms, while they relate to power and thrust, denote different concepts or outcomes in aerodynamics, such as excess power or output, which may not pertain directly to the specific amount of power required for thrust generation.
