Question 696Navigation General

The correct answer is A) height error. An aneroid barometer reading must be corrected for height error, which is the change in atmospheric pressure due to the difference in elevation between the barometer's location and the reference height. As you move higher in elevation, the atmospheric pressure decreases, so the barometer reading must be adjusted accordingly. Neither gravity error nor temperature error are corrections that need to be applied to an aneroid barometer reading, so options B and C are incorrect.
