  • calibrated air speed — An indicated air speed corrected for instrument and installation (pressure/position) errors. At mean sea level in the ISA (international standard atmosphere), the CAS is equal to true air speed …   Aviation dictionary

  • air( )speed — The speed of an aircraft relative to its surrounding air mass. The term air speed can mean any one of the following: indicated air speed, calibrated air speed, equivalent air speed, and true air speed. Indicated air speed (indicated air speed) or …   Aviation dictionary

  • equivalent air speed — The calibrated air speed of an aircraft corrected for adiabatic compressible airflow for the particular altitude. It is the indicated air speed corrected for inherent errors within the instrument and errors caused by compression of the air inside …   Aviation dictionary

  • rectified air speed — The indicated air speed corrected for instrument and installation (pressure/position) errors. At mean sea level in the international standard atmosphere (ISA), the RAS will be equal to true air speed. Also known as calibrated air speed (CAS) …   Aviation dictionary

  • True air speed — Die True Airspeed (TAS) ist die wahre Geschwindigkeit eines Flugzeuges gegenüber der umgebenden Luft. Durch ein Staurohr am vorderen Flugzeugrumpf (bei Kleinflugzeugen meist unter der Flügelvorderkante) wird am Fahrtmesser (engl. Airspeed… …   Deutsch Wikipedia

  • true air speed — The actual speed of an aircraft relative to the air through which it flies (i.e., the calibrated air speed corrected for temperature, density, and compressibility). If the compressibility effects are ignored, then the IAS equals the product of… …   Aviation dictionary

  • indicated air speed — The uncorrected reading of the air speed indicator. It is calibrated to reflect standard atmospheric adiabatic compressible flow at sea level uncorrected for air speed system errors. It is equal to 1/2 ρV2 , where ρ is density and V is true air… …   Aviation dictionary

  • Air gun — Air rifle and Air pistol redirect here. For other uses, see Air gun (disambiguation) An air gun (air rifle or air pistol) is a rifle or pistol which fires projectiles by means of compressed air or other gas, (in contrast to a firearm which uses… …   Wikipedia

  • Speed to fly — is a principle used by soaring pilots when flying between sources of lift, usually thermals, ridge lift and wave. The aim is to maximize the average cross country speed by optimizing the airspeed in both rising and sinking air. The optimal… …   Wikipedia

  • never-exceed speed — The speed beyond which it is not safe to fly an aircraft. It is normally less than the maximum diving speed (VD ). As it concerns rotary wing aircraft, the never exceed speed, VNE , must be established so that it is (i) not less than 40 knots… …   Aviation dictionary

  • Air data computer — An air data computer is an essential avionics component found in modern glass cockpits. This computer, rather than individual instruments, can determine the calibrated airspeed, Mach number, altitude, and altitude trend data from an aircraft s… …   Wikipedia
