What is a primary focus of the pitot-static system?

The primary focus of the pitot-static system is to deliver data for altitude and airspeed readings. This system is essential for the operation of various flight instruments, such as the altimeter and airspeed indicator. The pitot tube measures dynamic pressure, which is the difference between ambient atmospheric pressure and the pressure of the fluid (air) in motion. This allows the airspeed indicator to provide an accurate reading of the aircraft's speed relative to the surrounding air.

Meanwhile, the static port measures the ambient atmospheric pressure, which the altimeter uses to determine altitude above sea level. By combining the data from these two sources, the pitot-static system effectively fulfills its primary function of providing critical flight performance information - namely, the altitude and airspeed - which pilots rely on to ensure safe flight operations.
