What does OEI stand for in engine-out performance discussions?

Explanation:
In discussions of engine-out performance, OEI refers to One Engine Inoperative, the standard scenario used to analyze how a multi-engine aircraft behaves when one engine fails and the other continues to operate. It’s the benchmark for evaluating safety margins, climb capability, and handling under single-engine operation, which is critical during things like takeoff performance and flight planning. The other options don’t align with common aviation terminology in this context: they don’t describe the established concept of losing one engine and continuing flight.
