What is the engine type used in the aircraft specifications?

• A. GE CF-34 85C B1
• B. GE CF-34 100C
• C. GE CF-6
• D. Pratt & Whitney PW4000

Answer: (A)

The key idea is recognizing the engine family and the specific variant listed in the aircraft’s specifications. For GoJet’s regional jets, the engines come from GE’s CF34 family, and the exact model is shown as the 85C B1 variant. This tells you not only the engine type (CF34) but also the thrust class and version (85C B1), which matches the performance data in the specs. The other options belong to different engine families or higher-thrust variants that don’t align with the given specifications, so they aren’t the correct match for this aircraft.
