What is the function of the pitot-static system?

The pitot-static system provides the pressure references that the airspeed, altitude, and vertical speed instruments rely on. It uses two pressure sources: pitot (total) pressure from the pitot tube, which captures ram air as the aircraft moves, and ambient static pressure from static ports. The airspeed indicator uses the difference between total pressure and static pressure (dynamic pressure) to display airspeed. The altimeter and the vertical speed indicator depend on static pressure: the altimeter converts static pressure into altitude, while the vertical speed indicator shows how quickly static pressure is changing, indicating climb or descent rate. So the function is to supply total and static pressures to those instruments.
