<Li> KEAS is "knots equivalent airspeed", the calibrated airspeed corrected for adiabatic compressible flow for the particular altitude </Li> <P> The indicated airspeed is close to the true airspeed only at sea level in standard conditions and at low speeds . At 11 000 m (36 000 ft), an indicated airspeed of 300 kn may correspond to a true airspeed of 500 kn in standard conditions . </P>

Knot is unit of speed of which of the following
