Above Ground Level Used in reference to altitude, e.g. 5000 ft AGL - see also: MSL (Mean Sea Level)

The speed of an aircraft relative to its surrounding air mass - see also: CAS; IAS; TAS

The barometric pressure reading used to adjust a pressure altimeter for variations in existing atmospheric pressure or to the standard altimeter setting (29.92 inches of Hg)

The angle between the chord line of the wing of an aircraft and the relative wind

The recommended speed contained in aircraft manuals used by pilots when making an approach to landing. This speed will vary for different segments of an approach as well as for aircraft weight and con [..]

The indicated airspeed of an aircraft, corrected for position and instrument error Calibrated airspeed is equal to true airspeed in standard atmosphere at sea level

A line drawn from the leading edge of the wing to the trailing edge
