airspeed correction
1Airspeed — 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 …
2Airspeed indicator — The airspeed indicator or airspeed gauge is an instrument used in an aircraft to display the craft s airspeed, typically in knots, to the pilot. Markings Light aircraft Airspeed indicator markings use a set of standardized colored bands and lines …
3Equivalent 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… …
4Calibrated 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… …
5True airspeed — (TAS) is the speed of an aircraft relative to the airmass in which it flies, i.e. the magnitude of the vector difference of the velocity of the aircraft and the velocity of the air. Under zero wind conditions and in horizontal flight, this is… …
6Indicated airspeed — (IAS) is the airspeed read directly from the airspeed indicator on an aircraft, driven by the pitot static system. IAS is directly related to calibrated airspeed (CAS), but includes instrument errors and position error.An aircraft s indicated… …
7compressibility correction — A correction applied to rectified airspeed to get equivalent airspeed. This correction is always negative but is generally negligible below 200 to 240 knots …
8E6B — pilots will still carry and use these Flight Computers. These flight computers are used during flight planning (on the ground before takeoff) to aid in calculating fuel burn, wind correction, time en route, and other items. In the air, the flight …

10Course Setting Bomb Sight — The CSBS Mk. IX mounted in a Fairey Battle. The bomb aimer is sighting through the white ring shaped backsights to the pin shaped foresights (just visible against the armoured cable) and holding the bomb release switch in his right hand. The… …
