WebSep 20, 2011 · Ice crystals blocked the pitot probes on two Airbus A330s that were cruising at high altitudes in the vicinity of convective weather activity, causing erroneous airspeed indications and reduced autoflight systems operation, according to a report issued in June by the U.S. National Transportation Safety Board (NTSB). A blocked pitot tube is a pitot-static problem that will only affect airspeed indicators. A blocked pitot tube will cause the airspeed indicator to register an increase in airspeed when the aircraft climbs, even though actual airspeed is constant. See more 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 See more The pitot-static system of instruments uses the principle of air pressure gradient. It works by measuring pressures or pressure differences and using these values to assess the speed and altitude. These pressures can be measured either from the static port … See more There are several situations that can affect the accuracy of the pitot-static instruments. Some of these involve failures of the pitot-static system itself—which may … See more • Air data boom • Air data inertial reference unit • Austral Líneas Aéreas Flight 2553 • Position error See more The pitot-static system obtains pressures for interpretation by the pitot-static instruments.

WebFeb 2, 2024 · The pitot-static system is one of the most simple systems that your aircraft has, yet also one of the most important. It is suffice to know that the pitot-static system supplies three very important instruments, namely the airspeed indicator (ASI), altimeter and vertical speed indicator(VSI), with air pressure from the outside in order for them to … WebThe sources you’ve read are referring to a complete blockage.
