equivalent air speed
equivalent air speed n (Aeronautics) the speed at sea level that would produce the same Pitot-static tube reading as that measured at altitude equivalent air speed
equivalent air speed (EAS)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 the pitot tube. Equivalent air speed is equal to calibrated air speed in the standard atmosphere at sea level. |
