Airspeed Indicator
An instrument measured in knots, is used in an aircraft to display the aircraft's airspeed to the pilot. The “ASI” is also the abbreviation of the Airspeed indicator.
The ASI is used by the pilot during all phases of flight, from take-off, climb, cruise, descent and landing in order to maintain airspeeds and flight conditions.

Internal Mechanism Of Airspeed Indicator
HOW EASY THE MECHANISM WORKS !!
-
Total pressure is being applied into the diaphragm
-
Static pressure is fed into the instrument casing
-
Diaphragm deflects according to the difference in pressure between the internal and external of the diaphragm
-
Transmits to the mechanical linkages and the pointer
