What is the main function of the Pitot-static system in aircraft?

The primary function of the Pitot-static system in aircraft is to provide critical information about airspeed and altitude by measuring air pressure. This system consists of two main components: the Pitot tube, which measures dynamic air pressure (the pressure exerted by the movement of air against the aircraft), and the static ports, which measure static air pressure (the ambient pressure of the atmosphere).

By utilizing these two pressure measurements, the aircraft's instruments can calculate true airspeed and altitude. This information is essential for pilots to navigate safely, maintain proper flight performance, and comply with aviation regulations. The accurate readings from the Pitot-static system directly influence flight dynamics, contributing to the overall safety and efficiency of the flight operation.
