1. Position error affects the indicated airspeed and the indicated altitude. 2. Indicated airspeed for diving was set at.3. The equivalent airspeed is closely related to the indicated airspeed shown by the airspeed indicator. 4. The speeds needed for takeoff are relative to the motion of the air ( indicated airspeed ). 5. The refueling speed envelope has been widened from 100 to indicated airspeed , offering more capability and flexibility. 6. The indicated airspeed is close to the true airspeed only at sea level in standard conditions and at low speeds. 7. At, an indicated airspeed of 300 kn may correspond to a true airspeed of 500 kn in standard conditions. 8. This measurement is converted to an equivalent airspeed based upon known atmospheric conditions and measured errors in the indicated airspeed system. 9. In some low-speed aircraft, the position error is shown as the difference between indicated airspeed and equivalent airspeed. 10. Indicated airspeed ( IAS ) is the airspeed indicator reading ( ASIR ) uncorrected for instrument, position, and other errors.
