What information do the PFD, ND, and ECAM displays provide to the crew on a narrowbody?

• A. PFD shows attitude, airspeed, and altitude; ND shows route, weather, and traffic; ECAM shows system status and abnormal warnings.
• B. PFD shows weather radar; ND shows altitude; ECAM shows flight plan.
• C. PFD shows only heading; ND shows airspeed; ECAM shows cabin temperature.
• D. PFD shows route; ND shows attitude; ECAM shows fuel consumption.

Answer: (A)

PFD, ND, and ECAM each present a different set of information that pilots rely on during flight. The primary flight display shows the core flight data: attitude (the aircraft’s orientation), airspeed, and altitude, with vertical speed and flight director cues to guide steering and autoland/autopilot as needed. The navigation display complements that by presenting the flight’s route on a map, plus navigation context such as traffic, weather radar overlays, terrain, and waypoints along the flight plan. The ECAM focuses on the health of the aircraft’s systems, listing current system status and any abnormal conditions with recommended actions or checklists to manage faults. So the combination described in this option—PFD giving attitude, airspeed, and altitude; ND giving route, weather, and traffic; ECAM giving system status and abnormal warnings—is the best match.
