WebTools. The airspeed indicator ( ASI) or airspeed gauge is a flight instrument indicating the airspeed of an aircraft in kilometers per hour (km/h), knots (kn), miles per hour (MPH) and/or meters per second (m/s). The recommendation by ICAO is to use km/h, however knots is currently the most used unit. The ASI measures the pressure differential ... WebMar 24, 2016 · To clarify: Indicated airspeed is essentially a measure of dynamic pressure, which is corrected to the free-field value (i.e. without the presence of the aircraft) as CAS. CAS is equal to TAS at standard sea level air density, but decreases as air density decreases (e.g. with altitude).
