Pitot-Static System
The Pitot – Static System is one method to measure the true airspeed and indicate it on the Air Speed Indicator (ASI). This system allows the pilots to know if the airplane is speeding or dropping in speed as if the aircraft is speeding, it could cause structural failure as certain aircrafts are not allowed to go to a certain speed in full load
How It Works
Pitot tube is sensed through an open-end tube pointed directly into the relative wind flowing around the aircraft. The Pitot tube is then connected to the ASI or an air data computer to relay the airspeed. The static ports are also used to determine the Vertical Air Speed (VSI) and the altitude via the Altimeter.
The Pitot tube is designed to be heated while flying as this is to prevent buildup of ice at higher altitudes on the tube.
