Static vent

A static vent is a small opening located on the skin of an aircraft where the incoming air is least disturbed. The vent serves as the primary source of atmospheric air pressure for altimeters, airspeed indicators, and vertical speed indicators. Essentially, it helps to ensure that the aircraft’s measurement systems are accurately calibrated and can provide precise information to the pilots. The static vent functions by channeling the incoming air to a port that leads to the aircraft’s pressure sensors. The pressure measurements obtained from the static vent can then be compared to other pressure measurements, such as those from the pitot tube, to calculate the aircraft’s altitude and speed. It is important to note that a static vent must remain clear and unobstructed at all times, as any blockage could result in incorrect readings and potentially dangerous situations during flight.
