Which sources does an airspeed indicator use for readings?

Explanation:
Airspeed is determined from dynamic pressure, which comes from the difference between the total (ram) pressure sensed by the Pitot tube and the ambient static pressure sensed by the static ports. The Pitot tube provides the ram pressure as you move through the air, while the static ports supply the surrounding air pressure. The instrument then converts this pressure difference into a speed reading. If either source is blocked or inaccurate, the reading can be off, since you need both pressures to establish the dynamic pressure. So, the airspeed indicator uses both Pitot and static pressures.
