Power available is the power which can be obtained from the propeller. You wanted something simple to understand -- @ruben3d's model does not advance understanding. In this text we will assume that such errors can indeed be neglected and the term indicated airspeed will be used interchangeably with sea level equivalent airspeed. \begin{align*} CC BY 4.0. Your airplane stays in the air when lift counteracts weight. the arbitrary functions drawn that happen to resemble the observed behavior do not have any explanatory value. In the case of the thrust required or drag this was accomplished by merely plotting the drag in terms of sea level equivalent velocity. CC BY 4.0. This is the base drag term and it is logical that for the basic airplane shape the drag will increase as the dynamic pressure increases. This is a very powerful technique capable of modeling very complex flows -- and the fundamental equations and approach are pretty simple -- but it doesn't always provide very satisfying understanding because we lose a lot of transparency in the computational brute force. @ruben3d suggests one fairly simple approach that can recover behavior to some extent. It is interesting that if we are working with a jet where thrust is constant with respect to speed, the equations above give zero power at zero speed.

CC BY 4.0. Instead, there is the fascinating field of aerodynamics. How does airfoil affect the coefficient of lift vs. AOA slope? What is the relation between the Lift Coefficient and the Angle of Attack? The conversion is, We will speak of two types of power; power available and power required. Using the two values of thrust available we can solve for the velocity limits at sea level and at l0,000 ft. These solutions are, of course, double valued. Can you still use Commanders Strike if the only attack available to forego is an attack against an ally?
