Airspeed indicator. The airspeed indicator (ASI) or airspeed gauge is a flight instrument indicating the airspeed of an aircraft in kilometres per hour (km/h), knots (kn or kt), miles per hour (MPH) and/or metres per second (m/s). The recommendation by ICAO is to use km/h, however knots (kt) is currently the most used unit.
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 static port, and the pitot–static instruments. [1] Other instruments that might be connected are ...
In an ideal static system the air pressure fed to the altimeter and airspeed indicator is equal to the pressure of the air at the altitude at which the aircraft is flying. As the air flows past an aircraft in flight, the streamlines are affected by the presence of the aircraft, and the speed of the air relative to the aircraft is different at ...
Indicated airspeed (IAS) is the airspeed of an aircraft as measured by its pitot-static system [1] and displayed by the airspeed indicator (ASI). [2] This is the pilots' primary airspeed reference. This value is not corrected for installation error, instrument error, or the actual encountered air density, [2] being instead calibrated to always ...
An inertial navigation system (INS; also inertial guidance system, inertial instrument) is a navigation device that uses motion sensors (accelerometers), rotation sensors (gyroscopes) and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object ...
Stall (fluid dynamics) Airflow separating from an airfoil at a high angle of attack, as occurs at a stall. In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack exceeds its critical value. [1] The critical angle of attack is typically about 15°, but it may vary significantly depending on the ...
E6B. The front of a metal E6B. The E6B flight computer is a form of circular slide rule used in aviation. It is an instance of an analog calculating device still being used in the 21st century. An E6B flight computer commonly used by student pilots. They are mostly used in flight training, because these flight computers have been replaced with ...
V speeds. A single-engined Cessna 150L's airspeed indicator indicating its V-speeds in knots. In aviation, V-speeds are standard terms used to define airspeeds important or useful to the operation of all aircraft. [1] These speeds are derived from data obtained by aircraft designers and manufacturers during flight testing for aircraft type ...
