WebCalibrated airspeed is the value that would be obtained from the qc equation if measurements were made at sea level on a standard day at which ρ = ρ 0 = 0.002378 slug per cubic feet. The above measurements of speed also require a measurement of local outside air temperature. WebIndicated air speed (VIAS) is the speed indicated in the cockpit based upon the above calibration. • Calibrated air speed (VCAS) is approximately equal to VIAS with the only difference being a small adjustment to allow for aircraft disturbance of the static pressure field around the pitot-static probe. •
