The static pressure is obtained through a static port. When airspeed increases, the ram air pressure is increased, which can be translated by the airspeed indicator. By situating the pitot tube in such a location, the ram air pressure is more accurately measured since it will be less distorted by the aircraft's structure. The pitot tube is most often located on the wing or front section of an aircraft, facing forward, where its opening is exposed to the relative wind. The pitot pressure is a measure of ram air pressure (the air pressure created by vehicle motion or the air ramming into the tube), which, under ideal conditions, is equal to stagnation pressure, also called total pressure. ![]() The pitot pressure is obtained from the pitot tube. The static pressure is used in all measurements, while the pitot pressure is used only to determine airspeed. These pressures can be measured either from the static port (static pressure) or the pitot tube (pitot pressure). It works by measuring pressures or pressure differences and using these values to assess the speed and altitude. The pitot-static system of instruments uses the principle of air pressure gradient. Static ports fitted to an Airbus A330 passenger airliner. ![]()
