Which display primarily shows primary flight data such as attitude, airspeed, and altitude?

• A. Navigation Display
• B. Engine Indicating and Crew Alerting
• C. Primary Flight Display
• D. Multifunction Display

Answer: (C)

The main function is to present the essential flight state in one glance. The Primary Flight Display does exactly that by centralizing critical flight data—attitude (the artificial horizon), airspeed, and altitude—on a single screen, usually with speed and altitude tapes and the horizon front and center. This arrangement lets the pilot quickly assess how the aircraft is oriented and performing, which is crucial during all phases of flight. Other displays serve different roles: the Navigation Display shows the aircraft’s position, route, and nav information; the Engine Indicating and Crew Alerting System presents engine parameters and alerts; the Multifunction Display can show a variety of data or charts but isn’t dedicated to primary flight data.
