What is the function of the Static Source on the Pilatus PC-12 NG?

The function of the Static Source on the Pilatus PC-12 NG is to provide pressure information to the airspeed indicator and altimeter. This static pressure is essential for the accurate measurement of altitude and airspeed, which are critical for safe flight operations.

The static source collects atmospheric pressure data that helps the altimeter determine the aircraft's altitude relative to sea level. Similarly, the information is used by the airspeed indicator to calculate the dynamic pressure necessary to display the correct airspeed. This reliance on static pressure ensures that pilots have reliable data for altitude and speed management, which is crucial for navigation and safety during flight.

The other functions provided in the options, such as measuring engine temperature, controlling cabin pressurization, or assisting in navigation, are handled by different systems within the aircraft and are not the role of the static source. Understanding this functionality is vital for pilots to interpret their instruments accurately and make informed decisions in various flight situations.
