Final answer:
The airspeed described is indicated airspeed (IAS), which is the speed of an aircraft shown on a pitot static airspeed indicator. It is calibrated to reflect standard atmosphere adiabatic compressible flow at sea level and is uncorrected for airspeed system errors.
Step-by-step explanation:
The airspeed described in the definition is indicated airspeed (IAS). Indicated airspeed is the speed of an aircraft as shown on a pitot static airspeed indicator, which is calibrated to reflect standard atmosphere adiabatic compressible flow at sea level and is uncorrected for airspeed system errors. IAS does not take into account factors such as altitude, temperature, or air density.
