Question 1113Navigation General

The correct answer is C) elevation. An aneroid barometer measures atmospheric pressure, which is affected by changes in elevation. As you go higher in elevation, the atmospheric pressure decreases. Therefore, a standard correction must be applied to the aneroid barometer reading to account for the change in elevation from the location where the barometer was calibrated. This is known as the elevation correction. The other options are incorrect because temperature, wind speed, and latitude do not directly affect the reading of an aneroid barometer in the same way that elevation does. These factors may influence atmospheric pressure, but they are not standard corrections applied to the aneroid barometer itself.
