What is the main function of the pitot-static system?

The main function of the pitot-static system is to provide accurate readings of airspeed, altitude, and vertical speed. This system consists primarily of the pitot tube and static ports, which together gather essential aerodynamic data.

The pitot tube measures dynamic pressure from the air flowing into it, which is then used to calculate the aircraft's airspeed. The static ports measure ambient atmospheric pressure, which allows for accurate altitude readings and vertical speed indicators. By processing the data collected from these components, pilots receive critical information required for safe flight operations, including speed management and altitude maintenance.

Understanding this system is fundamental for pilots, as reliance on precise airspeed and altitude information is crucial for navigation, performance calculations, and overall safety in flight operations.
