Plain English Meaning

The speed your airspeed indicator is showing you right now, straight off the dial, before any corrections are applied.

Full Definition

The airspeed shown directly on the airspeed indicator in the cockpit, expressed in knots. It is derived from the difference between ram air pressure (from the pitot tube) and static air pressure (from the static port), and is uncorrected for instrument error, installation error, or variations in air density due to altitude and temperature.
