A 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. A pitot–static system generally consists of a pitot tube, a static port, and the pitot–static instruments. [1]
Its services include component repair and overhaul, ground support test equipment, and airline service programs. Barfield's business concentration includes support programs for regional and longer haul airlines, comprising narrow and wide body fleets, and also manufactures and distributes a full line of ground support test equipment.
A pitot-static system generally consists of a pitot tube, a static port, and the pitot-static instruments. [5] 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. Several commercial airline incidents and accidents have been ...
They commonly have the pitot and static pressure inputs, as well as outside air temperature from a platinum resistance thermometer and may control heating of the pitot tube and static vent to prevent blockage due to ice. On simpler aircraft, there is usually not a fly-by-wire system so the outputs are typically to the cockpit altimeters or ...
The measurement and indication of airspeed is ordinarily accomplished on board an aircraft by an airspeed indicator (ASI) connected to a pitot-static system. The pitot-static system comprises one or more pitot probes (or tubes) facing the on-coming air flow to measure pitot pressure (also called stagnation, total or ram pressure) and one or ...
The pitot tube may become blocked, because of insects, dirt or failure to remove the pitot cover. A blockage will prevent ram air from entering the system. If the pitot opening is blocked, but the drain hole is open, the system pressure will drop to ambient pressure, and the ASI pointer will drop to a zero reading. If both the opening and drain ...
As the year comes to a close, experts from the Alzheimer's Association reflect on some of the hopeful advances in diagnosis, treatment and risk management that have been made in 2024.
It does this by giving an accurate measurement of the ambient atmospheric pressure (static pressure) well clear of the aircraft's fuselage. The trailing cone system trails at least one fuselage length behind the aircraft (SpaceAge Control) via a high-strength pressure tube. Static pressure is measured forward of the cone by several static ports.
