The altimeter is a device which gives attitude indications by measuring atmospheric pressure. Air is more dense at the surface of the earth than aloft.

Слайд 1Altimeter

Слайд 2The altimeter is a device which gives attitude indications by measuring

atmospheric pressure. Air is more dense at the surface of the earth than aloft.

The altimeter is a device which gives attitude indications by measuring atmospheric pressure. Air is more dense

Слайд 3As altitude increases, the atmospheric pressure decreases. This difference in pressure

at various levels causes the altimeter to indicate changes in altitude.

As altitude increases, the atmospheric pressure decreases. This difference in pressure at various levels causes the altimeter

Слайд 4The altimeter is simply a barometer that measures the pressure of

the atmosphere, and presents an altitude indication to the pilot in definite units.

The altimeter is simply a barometer that measures the pressure of the atmosphere, and presents an altitude

Слайд 5Knowing the aircraft's altitude is vitally important to the pilot for

several reasons:
He must be sure that he is flying high enough to clear the highest terrain or obstruction along his intended route; this is especially important when visibility is poor.
To keep above mountain peaks, the pilot must note the altitude of the aircraft and elevation of the surrounding terrain at all times.
To reduce the potential of a midair collision, the pilot must be sure he is flying the correct altitudes in accordance with air traffic rules

Knowing the aircraft's altitude is vitally important to the pilot for several reasons:He must be sure that

Слайд 6Often he will fly at a certain altitude to take advantage

of favorable winds and weather conditions. Also, know, edge of the altitude is necessary to calculate true airspeeds.

Often he will fly at a certain altitude to take advantage of favorable winds and weather conditions.

Слайд 7altimeter location

Слайд 8There are two types of altimeter

Слайд 9Radio altimeter
The radio altimeter is based on the use of the

wave propagation law. Radio waves propagate at a constant speed and are reflected from various locations and return to the aircraft, and then on the indicator, the value of the direct and reflected radio signal is compared to determine the true altitude.
