equivalent airspeed
- Definição1
- 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.

- Definição2
- Airspeed equivalent to CAS in standard atmosphere at sea level. As the airspeed and pressure altitude increase, the CAS becomes higher than it should be, and a correction for compression must be subtracted from the CAS.

- Contexto
- At that time, the aircraft's equivalent airspeed was about 229 knots (245 knots indicated) and its mach number was about 0.80, and according to the manufacturer's flight test and windtunnel test data, the airloads on the slat would have subjected the slat actuator rod to a compressive load of about 700 pounds, and about 9 percent less if the right outboard aileron was floating.
