In aircraft, pilot's rely on three primary pressure-based instruments for pressure readings. These instruments comprise the airspeed indicator, the altimeter, and the vertical speed indicator, all of which function within the pitot static system. To understand in general how this system works, it is useful to understand the relationships between pressure and velocity as they relate to static pressure, total pressure, and dynamic pressure. This blog will offer a brief overview of the aircraft pitot static system and the functions of its main instruments.
