What is the term for the cover around an aircraft engine?

• A. Concourse
• B. Cruising Altitude
• C. Clearance
• D. Cowling

Answer: (D)

The cover around an aircraft engine is called cowling. It’s the outer shell that encloses the engine, shaping the aircraft to reduce drag and housing air intakes and cooling passages, while also providing access panels for maintenance. The other terms don’t fit this idea—concourse is the terminal area in an airport, cruising altitude is the height at which the plane flies, and clearance refers to permission or distance for safe operation. So the engine’s cover is best described as cowling.
