Q

The correction(s) which must be applied to an aneroid barometer reading include(s) __________.

🔍 Key Concepts

• Aneroid barometer construction and how it measures pressure • Standard corrections normally applied to barometer readings in navigation texts • Difference between corrections applied to mercurial barometers and aneroid barometers

💭 Think About

• Think about which physical factors actually change the pressure reading versus which affect how the instrument responds to pressure. • Consider how the barometer’s location on the vessel (above or below sea level) might influence the reading. • Ask yourself: what corrections are usually listed together in barometer tables in nautical almanacs or navigation manuals?

✅ Before You Answer

• Verify which errors are specifically associated with local height above sea level. • Check whether gravity variation with latitude affects aneroid barometers the same way as mercury barometers. • Confirm if temperature influences the mechanism or scale of aneroid barometers and whether manuals recommend a temperature correction.
