flight instrumentsFAA-published sample question (FIA, Aug 2021)
What is pressure altitude?
A
The indicated altitude corrected for position and installation error.
B
The altitude indicated when the barometric pressure scale is set to 29.92.✓ Correct Answer
C
The indicated altitude corrected for nonstandard temperature and pressure.
Explanation
PHAK defines pressure altitude as the altitude indicated when the altimeter's barometric scale is set to 29.92 inches Hg (the standard datum plane). Correcting for installation error gives calibrated altitude, and correcting for nonstandard temperature gives density altitude.
