What is the primary role of an aircraft's pitot-static system?

The primary role of an aircraft's pitot-static system is to measure airspeed, altitude, and vertical speed. This system consists of a pitot tube and static ports that capture dynamic and static air pressure respectively. The pitot tube measures the air pressure caused by the aircraft's forward motion, providing information necessary to calculate airspeed. Meanwhile, the static ports measure the ambient atmospheric pressure, which is essential for determining altitude and vertical speed.

This system is critical for safe aircraft operation, as accurate readings of airspeed and altitude are vital for controlling the aircraft during various phases of flight, such as takeoff, cruising, and landing. By relying on the pitot-static system, pilots can make informed decisions based on real-time data regarding their aircraft’s performance, helping to ensure a safe and efficient flight.
