The French air safety authority BEA said that pitot tube icing was a contributing factor in the crash of Air France Flight 447 into the Atlantic Ocean. Examples include Austral Líneas Aéreas Flight 2553, Northwest Airlines Flight 6231, Birgenair Flight 301 and one of the two X-31s. Several commercial airline incidents and accidents have been traced to a failure of the pitot-static system. Errors in pitot-static system readings can be extremely dangerous as the information obtained from the pitot static system, such as airspeed, is potentially safety-critical.

A pitot-static system generally consists of a pitot tube, a static port, and the pitot-static instruments.

Aircraft and accidents Ī pitot-static system is a system of pressure-sensitive instruments that is most often used in aviation to determine an aircraft's airspeed, Mach number, altitude, and altitude trend. Which can also be written p t = p s + ( ρ u 2 2 ). However, Bernoulli's equation states: Stagnation pressure = static pressure + dynamic pressure The measured stagnation pressure cannot itself be used to determine the fluid flow velocity (airspeed in aviation). This pressure is the stagnation pressure of the fluid, also known as the total pressure or (particularly in aviation) the pitot pressure. As this tube contains fluid, a pressure can be measured the moving fluid is brought to rest (stagnates) as there is no outlet to allow flow to continue. The basic pitot tube consists of a tube pointing directly into the fluid flow.
