CRJ700飛機(jī)定義：

IAS Indicated airspeed – Airspeed indicator reading corrected for instrument error. Values in this manual assume zero instrument error.
CAS Calibrated airspeed – Indicated airspeed corrected for static source position error.
EAS Equivalent airspeed – Calibrated airspeed corrected for compressibility.
TAS True airspeed – Equivalent airspeed corrected for density.
MI Indicated Mach number – Machmeter reading corrected for instrument error.
MT True Mach number – Machmeter reading corrected for both instrument and static source position errors.
V1 Take-off decision speed (formerly designated as critical engine failure recognition speed) – The speed used as a reference at which, due to engine failure or other causes, the pilot may elect to stop or continue the take-off.
V1MBE Maximum V1 for brake energy – The maximum speed on the ground from which a stop can be accomplished within the energy capabilities of the brakes.
V1MCG Minimum V1 limited by control on the ground – The take-off decision speed following an engine failure at VMCG. V1 may not be less than V1MCG.
V2 Take-off safety speed – Target climb speed to be attained at or before a height of 35 feet above the runway during a continued take-off, following an engine failure.
V2GA Approach climb speed (also known as V2 GO-AROUND) – Target climb speed to be attained during a go-around with one engine inoperative.
VA Design maneuvering speed – The maximum speed at which application of full available aileron, rudder or elevator will not overstress the airplane.
VEF Critical engine failure speed – The speed at which, if the critical engine fails, the engine failure is recognized at V1.
