An altimeter does not actually measure altitude directly, but rather just atmospheric pressure. So an altimeter is actually a barometer created for a specific purpose. The altimeter uses the changes in atmospheric pressure to determine the changes in altitude.
Instrumental errors of barometric altimeters and air data computers. Further errors lowering the accuracy of the altitude measurement by barometric mechanic. altimeters are instrumental errors caused by qualities of barometric boxes, it means hysteresis. and elastic after-effect, and also errors caused by the friction in the gear mechanism.
