Which type of pressure is the ambient outside air pressure sensed by the pitot-static system?

Explanation:
Ambient outside air pressure is sensed as static pressure. The static ports on the aircraft measure the undisturbed atmospheric pressure at the aircraft’s altitude, which is the ambient pressure of the air around you. The pitot tube, on the other hand, measures stagnation (total) pressure by facing the airstream and bringing it to rest; the difference between stagnation pressure and static pressure is dynamic pressure, which relates to airspeed. Cabin pressure is a separate, pressurized environment inside the aircraft and not the ambient outside air pressure.
