What is the purpose of the pitot-static system?

The pitot-static system plays a critical role in an aircraft's ability to gather essential flight information. Its primary purpose is to measure airspeed, altitude, and vertical speed, which are vital parameters for safe and effective flight operations.

The pitot tube, which is part of this system, measures dynamic pressure from the airflow, allowing for the calculation of the aircraft's airspeed. On the other hand, the static ports are used to sense the ambient atmospheric pressure, which is crucial for determining altitude and vertical speed. By monitoring changes in air pressure, the system provides pilots with real-time data necessary for maintaining control of the aircraft during various phases of flight.

This function distinguishes the pitot-static system from other systems that focus on different data, such as fuel consumption or engine performance. The accurate information provided by the pitot-static system is fundamental for effective navigation and flight safety.
