TH-73A Systems Practice Test

The pitot-static probe includes both total and static pressure ports, which is essential for measuring various aerodynamic properties of an aircraft. The total pressure port captures the air pressure entering the probe while in motion, providing a measure of dynamic pressure, which is vital for calculating airspeed. The static pressure port, on the other hand, measures the ambient atmospheric pressure, which is crucial for determining altitude and other static-related measurements.

By integrating both types of pressure measurements, the pitot-static system enables effective operation of the aircraft's airspeed indicator, altimeter, and vertical speed indicator, allowing pilots to obtain necessary flight information accurately. The presence of both ports is what distinguishes the pitot-static probe from other pressure measurement devices that may only focus on one aspect of pressure.
