Which type of airspeed is indicated on the airspeed indicator?

The type of airspeed that is indicated on the airspeed indicator is known as indicated airspeed. This is the reading displayed on the instrument and it reflects the dynamic pressure of the air mass surrounding the aircraft. Indicated airspeed is essential for understanding aircraft performance as it is used to determine stall speeds, maneuvering speeds, and other critical flying parameters that are vital for operation within various phases of flight.

Indicated airspeed is not corrected for instrument or systematic errors; it is simply the raw reading of the pressure differential calculated by the aircraft's airspeed sensor. It serves as the initial reference point for understanding the aircraft's speed through the air.
