Which instruments are derived from the Pitot Static System?

The altimeter and airspeed indicator are both directly connected to the Pitot Static System, which is essential in providing crucial flight information. The Pitot Static System comprises a Pitot tube, that measures dynamic pressure and is used to determine airspeed, and static ports, which measure atmospheric pressure.

The altimeter functions by comparing the static pressure obtained through the static ports to a pre-defined standard atmospheric pressure, translating this into altitude. Meanwhile, the airspeed indicator uses the dynamic pressure from the Pitot tube alongside the static pressure from the static ports to calculate the aircraft's speed relative to the surrounding air.

These instruments are vital for flight operations, as they offer critical data regarding altitude and airspeed, ensuring that pilots can make informed decisions during flight.
