indicated air-speed hold mode — In a flight control system, a control mode in which the desired indicated air speed of an aircraft is maintained automatically … 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( )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
air-speed indicator — An instrument to measure the speed of relative airflow. Pitot pressure (i.e., dynamic and static pressure) is taken into a capsule kept in an airtight case. Static pressure is fed into the case. The capsule is thus affected by dynamic pressure… … 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
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
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
air-speed hold — An autopilot mode that permits an aircraft’s indicated speed to be maintained. In fixed wing aircraft, this mode is normally used during climb, cruise, or descent. In helicopters, this control is provided through the cyclic stick … Aviation dictionary
Indicated 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… … Wikipedia
air data computer — An electronic digital computer in aircraft that senses or computes static and pitot pressure, outside air and total air temperature, IAS (indicated air speed), TAS (true air speed), pressure altitude, Mach number, angle of attack, and angle of… … Aviation dictionary
