Does the minimum rate of descent change with altitude?

Question

Yes, because the density is higher at lower altitudes the minimum rate of descent will be smaller.

Yes, because the pressure is higher at lower altitudes the minimum rate of descent will be smaller.

No, altitude does not have an effect on minimum rate of descent.

Yes, because the density is higher at lower altitudes the minimum rate of descent will be higher.

Answer 1

The correct response is:

Yes, because the density is higher at lower altitudes the minimum rate of descent will be smaller.

As altitude increases, air density decreases, which generally results in a higher minimum rate of descent for a given aircraft. At lower altitudes, where the air is denser, the aircraft can produce more lift for a given amount of power, leading to a lower minimum rate of descent.
