A method of measuring airflow velocity using an integrated heating airspeed tube where the integrated heating airspeed tube has a tube body and a heating component. The tube body is provided with a heating cavity, the heating component is located inside the heating cavity, and the heating component and the tube body are integrally formed. The heating component and at least two static pressure air inlet channels are physically separate but overlap in a lengthwise directly within a horizontal portion of the airspeed tube. The tube body integrally forms the static pressure air inlet channel, the dynamic pressure air inlet channel, the heating cavity, the dynamic pressure air inlet hole, and the static pressure air inlet hole as a unitary one-piece structure.
