An air speed indicator gives an indication of the speed of the air going across the wing surface. It's not a reflection of equivalent ground speed, as one's airspeed is subject to headwinds and such. However, before LORAN-C and GPS, it was the only real method of measuring any sort of speed. One could make an estimation of their ground speed based on airspeed.

How does an air speed indicator work?
Aircraft speedometers are based on the shock wave principle. the shock wave is directly proportional to the plane"s speed and this is determined through a pitot rube and also a static tube, which normally protrude from the wings,. There is the usual dial and speed indications. The Air Speed indicator measures Air speed. It is NOT based on wheel rotation as are speedometers on most land vehicles such as automobiles, trucks, and locomotives. For this reason airmen nearly always refer to the device as an Air Speed indicator, Not as a speedometer. there you have it.
How is the speed of an aircraft measured?
the speed is measured by using primary flight instrument...this instrument have air speed indicator by which v cn measure d speed of airplane..
The maximum speed at which the airplane can be operated in smooth air is?
This is known as the "never exceed" speed or VNE and is represented by a red line on the airspeed indicator.
What actually happened to the air France flight that crashed over the ocean?
The speed indicator froze and the aircraft stalled. It was Airbus' fault not Air France's.
What are the biological indicators for air pollution?
biological indicator of air pollution is lichene. it is a best example of air pollution indicator.
What are the errors in air speed indicator?
blocked pitot tube blocked static port density error compressibility error position errors
What instrument measures the speed of an airplane?
In aviation, the dial you look at to read your speed through the air is known as an IAS dial (indicated air speed). This dial is an indiaction only, as it works by measuring the amount of air entering the measuring tube (Pito tube); ergo a large head wind (blowing into the front of the aircraft) will give a higher indicated air speed than may actually be true.ias dial
What 3 instruments work on the pitot static system?
Airspeed indicator, alitimeter, and vertical speed indicator.
How do you determine if transmission on 1998 Plymouth voyager is three speed or four speed?
If the PRNDL indicator is electronic, it is a 4 speed
2003 that the brake indicator and ABS indicator light come on and the speed odometer stops working What causes this?
vss sensor
Name the instrument used for measuring the speed of an aeroplane?
The speed of an airplane is measured by a system known as the pitot-static system which compares the difference between the static air pressure that exists around the aircraft and the dynamic, or ram air pressure which is a function of the speed the aircraft is moving through the air. The devices used to gather this information are the static air port (which measures static air pressure) and the pitot tube (which measures ram air pressure). This differential is displayed on an instrument in the cockpit called an airspeed indicator (or ASI).
