WebAug 25, 2024 · To look at altitude changes we need to think in terms of energy changes. In climb we are turning kinetic and internal (engine) energy into an increase in potential energy. In a glide we are converting potential energy into velocity (kinetic energy) which will give us needed lift for flight. One of the questions above involved the rate of climb. WebFor those powerplants that experience a decay in thrust with an increase in altitude, the effect on the net accelerating force and acceleration rate can be approximated by assuming a direct variation with density. Actually, this assumed variation would closely approximate the effect on aircraft with high thrust-to-weight ratios.

WebIt has been established that a jet engine is more efficient at high altitudes partly because of reduced thrust. However, it is often very hard for a jet plane to climb and turn at the same time, when at these high altitudes. Therefore, little excess thrust should be made available for maneuvering when the need arises.

WebApr 27, 2024 · One of the more surprising outside factors that influence engine performance, is altitude.
