What is the purpose of the pitot-static system?

The pitot-static system is a crucial component in an aircraft, primarily designed to measure air pressure and provide important data for various flight instruments, particularly for speed and altitude indications. The pitot tube measures dynamic air pressure, which allows the calculation of airspeed, while the static port measures ambient atmospheric pressure, contributing to altitude and vertical speed readings.

This system helps pilots maintain situational awareness regarding their aircraft's performance and environmental conditions during flight. Accurate airspeed and altitude readings are essential for safe flight operations, navigation, and performance assessments.

While engine performance data, cabin altitude control, and cockpit air conditioning are important aspects of aircraft systems, they are not functions of the pitot-static system. Rather, those roles are fulfilled by separate systems designed for specific purposes.
