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]
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. [5]
Illustration of the airspeed indication and detection system on fly-by-wire aircraft. An air data module is a component of the navigation system. [1] Each unit converts pneumatic (air pressure) information from a pitot tube or a static port into numerical information which is sent on a data bus. [2]
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 ...
ATA 100 contains the reference to the ATA numbering system which is a common referencing standard for commercial aircraft documentation. This commonality permits greater ease of learning and understanding for pilots, aircraft maintenance technicians, and engineers alike.
An aircraft's indicated airspeed in knots is typically abbreviated KIAS for "Knots-Indicated Air Speed" (vs. KCAS for calibrated airspeed and KTAS for true airspeed). The IAS is an important value for the pilot because it is the indicated speeds which are specified in the aircraft flight manual for such important performance values as the stall ...
The ASI is the only flight instrument that uses both the static system and the pitot system. Static pressure enters the ASI case, while total pressure flexes the diaphragm, which is connected to the ASI pointer via mechanical linkage. The pressures are equal when the aircraft is stationary on the ground, and hence shows a reading of zero.
The blockage of all of the static ports is one of the few common-failure modes resulting in total failure of multiple basic flight instruments and, as such, is regarded as one of the most serious faults that can occur in avionics systems. [12] The design of the aircraft did not incorporate a system of maintenance covers for the static ports.
