compressibility error — An error in the airspeed indicator, which presumes that the air is incompressible. However, air is compressible and the higher the speed, the higher pressure it will indicate. An ASI (airspeed indicator) overreads because of the compressibility… … Aviation dictionary

Airspeed — is the speed of an aircraft relative to the air. There are several different measures of airspeed: indicated airspeed, calibrated airspeed, equivalent airspeed and true airspeed.It is measured within the flying aircraft with an airspeed indicator … Wikipedia
Calibrated airspeed — (CAS) is the speed shown by a conventional airspeed indicator after correction for instrument error and position error. Most EFIS diplays also show CAS. At high speeds and altitudes, calibrated airspeed is further corrected for compressibility… … Wikipedia
Equivalent airspeed — (EAS) is the airspeed at sea level which represents the same dynamic pressure as that flying at the true airspeed (TAS) at altitude. It is useful for predicting aircraft handling, aerodynamic loads, stalling etc.EAS = TAS imes sqrt{frac{actual… … Wikipedia
scale-altitude effect — An error in the air speed indicator at the speeds where the effects of compressibility start. At these high speeds, an air speed indicator overreads as if it were at a lower altitude. Another name for compressibility error … Aviation dictionary
Pitot-static system — A pitot static system is a system of pressure sensitive instruments that is most often used in aviation to determine an aircraft s airspeed, Mach number, altitude, and altitude trend. A pitot static system generally consists of a pitot tube, a… … Wikipedia
airspeed — The speed of an aircraft relative to its surrounding air mass. The unqualified term “airspeed” can mean any one of the following. a. calibrated airspeed Indicated airspeed corrected for instrument installation error. b. equivalent airspeed… … Military dictionary
