Question

The time taken to increase the specific total energy will be minimized by maximizing the SEP.

(a) True

(b) False

I have been asked this question by my school principal while I was bunking the class.

Asked question is from High Performance Climb in division Climb and Descent Performance of Aircraft Performance

Answer 1

The correct choice is (a) True

Explanation: The time taken to increase the specific total energy will be minimized by maximizing the SEP. The formula for SEP is given by [FN-D]\(\frac{V}{W}=\frac{d}{dt}\Big\{H+\frac{V^2}{2g}\Big\}\) where FN is force, D is drag, H is height, V is velocity, g is acceleration due to gravitation. SEP stands for specific excess power. It is equal to the rate of change of specific total energy (STE) and is used to increase the total energy of the aircraft which is in a combination with climb and acceleration.
