Noun
/ˈɛn.dʒɪn ɒn flaɪt/
An "engine-on flight" refers to a flight where the aircraft's engines are running, typically during takeoff, climbing, cruising, and landing phases. It implies that the airplane is in active operation, as opposed to being shut down on the ground or in other non-operational scenarios.
In English, this term is mainly used in the context of aviation, particularly when discussing flight operations, safety, and protocols. The phrase is used with notable frequency in written contexts, such as pilot manuals, aviation regulations, and industry reports, compared to oral speech.

The term "engine" originates from the Old French word "engine," meaning "a clever invention," which itself comes from the Latin "ingenium," meaning "innate quality, nature, or ability." The term has evolved to denote the machinery used for propulsion. "Flight" comes from the Old Norse word "flítr," relating to the action of flying, indicating movement through the air. The combination reflects a technical usage specific to aviation.
