The instrument used to measure an aircrafts altitude is an altimeter. It measures altitude above mean sea level (MSL).An altimeter estimates these measurements using static air pressure.The altimeter estimates altitude based on changes in atmospheric air pressure.
The estimated measurement is based on a system that sets standard atmospheric pressure and temperature. Altimeters are set in accordance with the international standard atmosphere (ISA).These international standards are used to calibrate the plain altimeter so that the pilot can estimate elevation.
The standard measurement is a starting point for calculating altitude.Due to varying temperatures around the world an international standard is inaccurate for measuring altitude. Aircraft altimeters are equipped with an adjustable setting dial. Pilots can adjust their altimeters to local settings for atmospheric pressure so that estimating altitude is more accurate. Many airports worldwide broadcast local atmospheric settings across the airwaves so that pilots can adjust to the conditions.
It is important for skydiving adventures that the altimeter is set in accordance with local atmospheric...
