The designation PC12 corresponds to which aircraft?

• A. Piper Malibu
• B. Piper Navajo
• C. Beech Baron
• D. Pilatus Eagle

Answer: (D)

Designer prefixes tied to the manufacturer reveal who built the aircraft. The PC prefix is used by Pilatus for its model line, with PC-6, PC-7, PC-9, PC-12, PC-21, and so on. The number is simply the model number within that line, not the engine or purpose. So a PC-12 is a Pilatus single‑engine turboprop designed for versatility as a light transport and utility aircraft.

Among the given options, the ones from Piper and Beech belong to their own designation systems (for example, Piper Malibu is PA-46, Piper Navajo is PA-31, and Beech Baron is a Model 58). There isn’t a standard Pilatus model officially called Eagle in the familiar designation scheme, so the correct association for PC-12 is Pilatus.
