What is density altitude?
A
The height above the standard datum plane.
B
The pressure altitude corrected for nonstandard temperature.✓ Correct Answer
C
The altitude read directly from the altimeter.
Explanation
PHAK defines density altitude as pressure altitude corrected for nonstandard temperature; it is the altitude in the standard atmosphere that has the same air density, and it governs aircraft performance. Height above the standard datum plane is pressure altitude, and the value read on the altimeter is indicated altitude.
