Indicated Airspeed
In the context of aerospace engineering, Indicated Airspeed (IAS) refers to the speed of an aircraft as shown on its pitot static airspeed indicator calibrated to reflect standard atmosphere adiabatic compressible flow at sea level uncorrected for airspeed system errors. It is the airspeed read directly from the airspeed indicator on an aircraft, uncorrected for altitude, nonstandard temperature and pressure, or instrument error. IAS is directly related to the physical pressures acting on the aircraft's surfaces and is important for aircraft control, particularly at low speeds and high angles of attack where the aircraft is close to the critical stall condition. It is used by the pilot during takeoff, climb, descent, approach, and landing because all aircraft performance charts are based on indicated airspeed. It is also the speed which is used in pilot/controller communications under the International Civil Aviation Organization (ICAO) standard atmosphere conditions.
