From where does the Air Data Computer receive static air pressure measurements?

The correct answer is that the Air Data Computer receives static air pressure measurements from the pitot-static probe. The pitot-static system is essential in aviation as it measures air pressure to provide key data regarding altitude, airspeed, and vertical speed among other parameters.

The pitot-static probe is equipped with both a pitot tube and static ports. The pitot tube measures dynamic pressure, which helps in determining airspeed, while the static ports measure the ambient static pressure of the atmosphere. The static pressure readings from the static ports are critical because they allow the Air Data Computer to compute altitude and other vital flight parameters accurately. This measurement is crucial for maintaining safe flight operations and ensuring that pilots have the necessary information to navigate effectively.

In contrast, the other options do not represent sources of static air pressure measurements. Weather radar, for instance, is used to detect precipitation and meteorological phenomena, not for measuring air pressure. A pressure sensor could refer to various types of sensors, but it is not specifically identified in the context of static air pressure measurement linked to the pitot-static system. An altitude sensor may sometimes refer to devices that derive altitude from various methods, but it is not the direct source of static air pressure measurements used in the air data system like
