Article Body:
The instrument used to measure an aircraft’s 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 pressure.Variations in pressure can
affect the estimation of altitude so it is important that altimeters are
set to local conditions.This will ensure the jump takes place at the
correct altitude.With adventure skydiving free fall time is at a maximum.
timing is crucial. Altitude measurements must be as accurate as possible
for increased safety.

Skydivers are advised to set their personal altimeters to local
atmospheric conditions at ground level.This will ensure they have an
accurate estimate of altitude during the jump. Altimeter settings are
also important when it comes to air traffic control.This is where an
internationally standardized altimeter reading is useful.If some planes
are flying with their settings adjusted to local conditions while others
are using ISA there is a greater risk of mid air collision.Many pilots
use local ISA when flying at low altitude and international ISA at higher
altitudes.
