What do thrust and power available depend on?

Thrust and power available are fundamentally linked to the actual thrust being produced by the aircraft's engines. This relationship is critical, as thrust directly affects an aircraft's ability to climb, accelerate, and maneuver. Thrust represents the forward force generated by the engines, while power is the measure of how effectively that thrust is used to perform work, especially in relation to the aircraft's speed and altitude.

At any point in flight, the engines work to generate a specific amount of thrust, which is influenced by engine design, operating conditions, and factors such as fuel flow and combustion efficiency. As such, understanding the actual thrust being produced gives insight into the overall performance capabilities of the aircraft, especially in various atmospheric conditions.

Other factors like altitude and temperature can influence engine performance indirectly but do not directly determine the thrust or power available. Similarly, wing size and shape are more related to lift rather than thrust, and while weight and balance are essential for overall aircraft performance, they do not directly dictate thrust or power generation from the engines. Consequently, the precise measure of thrust produced is the most crucial element in determining the power available to the aircraft.
