What component provides air data derived from the pitot-static system?

• A. Air data transducers
• B. Altimeter
• C. Gyroscope
• D. Rate gyro

Answer: (A)

Air data comes from sensing the pressures in the pitot-static system and then converting those pressures into usable signals for the cockpit instruments. The pitot tube provides dynamic pressure and the static port provides static pressure; air data transducers take these pressures and produce electrical signals (or pneumatic signals) that the air data computer and instruments use to display airspeed, altitude, and vertical speed. So the component that directly converts pitot-static pressures into the data used by the aircraft’s air data system is the air data transducer. The altimeter uses static pressure to show altitude but doesn’t convert pressures into data signals by itself, and gyroscopes measure angular motion rather than air pressures.
