The altimeter in an aircraft works the same as an aneroid barometer. Pressure differences with height act on a spring and diaphragm housing, which moves the needle around. There is a subscale and adjusting nut, which the pilot uses to set the sea level pressure for the area. The atmospheric pressure drops about 1 millibar every 30 feet. So if the altimeter subscale is set while on the ground, then the aircraft takes off, and climbs to 1000 feet, the pressure will be about 33 mbar less than on the ground, and the height indicating needle will read 1000.
type of sensors used in aeroplanes
Part of a turbine engine is the compressor. There are no others in aircraft.
Digital barometers, much like analog barometers, are used to forecast the weather using humidity, air pressure, and dew point. This answer needed a few more characters.
t
Mercury
They are more portable and can be used for airplane equipment
There are two types of barometers, Mercury barometers and then Aenroid barometers.
The pressure of air.
it measure the atmosphere.
they are used all over the world
Jet fuel is used in jet aircraft while high octane gasoline is used in propeller-driven craft.
The RAF has used many dozens of type of aircraft. You are probably tthinking of the famous Spitfires.
