Question

Maximum endurance is obtained at the point of minimum power to maintain the aircraft?

1) In steady, level flight
2) In a long range descent
3) At its slowest possible indicated airspeed

Answer 1

The student's question is about obtaining maximum endurance in aircraft under different flight conditions. The reference provided discusses power and air resistance in relation to aircraft performance, which is related but does not directly address the question of maximum endurance.

Step-by-step explanation:

The question at hand is addressing the concept of maximum endurance in aircraft, which is obtained at the point of minimum power required to maintain different flight conditions such as steady, level flight, a long range descent, or at the aircraft's slowest possible indicated airspeed.

However, the provided reference material discusses the topic of power required for an airplane to reach a certain speed and altitude, the power if it actually takes longer due to air resistance, and the average force of air resistance faced by the airplane over a given time period. This information pertains broadly to the subject of aircraft performance and the factors that affect it, such as air resistance and power, but does not directly answer the question of where maximum endurance is achieved.
