Question 1114Navigation General

The correct answer is D) Instrument error and height error. To read an aneroid barometer accurately, two corrections must be applied: 1. Instrument error: This accounts for any inherent inaccuracies or calibration issues with the specific aneroid barometer being used. 2. Height error: This corrects for the change in atmospheric pressure that occurs with changes in elevation above sea level. The other options are incorrect because latitude correction is not required for an aneroid barometer, and considering only one of the necessary corrections (instrument error or height error) would not provide a complete and accurate reading.
