The type of altimeter standardly used onboard aircraft is similar to an upgraded and enhanced version of a barometer. Maintaining a current altimeter setting is critical because the atmosphere pressure is never constant. When the altitude on your watch is falling and you are not descending in elevation, then it could indicate that the weather is clearing up. .
