What effect does high density altitude have on aircraft performance?

A

It increases engine performance.

B

It reduces climb performance.✓ Correct Answer

C

It increases takeoff performance.

Explanation

High density altitude means thinner air, which reduces engine power, propeller thrust and wing lift, so climb performance is reduced and takeoff distance increases (PHAK Chapter 11). It does not improve engine or takeoff performance.
