(a) True

(b) False

This question was addressed to me in my homework.

This intriguing question comes from Fixed-Wing Aircraft topic in chapter Fixed-Wing Aircraft Performance of Aircraft Performance

Answer 1

Right choice is (a) True

To elaborate: The elimination process will include an assumption of the environmental conditions of the atmosphere in which the aircraft will operate. Since the atmosphere is a very variable medium in that its pressure and temperature vary with height and also with geographical location and time. Performance estimation is based on assumption of International Standard Atmosphere (ISA).
