What is the critical engine, and why is it central to engine-out performance?

• A. The critical engine is the engine whose failure causes the greatest loss of performance and adverse yaw; its failure defines Vmc and influences OEI handling.
• B. The critical engine is the engine that produces the most thrust; its failure has no effect on OEI.
• C. The critical engine is the engine closest to the cockpit; its failure causes positive yaw.
• D. The critical engine is the engine with least maintenance; its failure sets the towing procedures.

Answer: (A)
