Question

Oil cooler flaps are at what on the ground? In air?

Answer 1

Oil cooler flaps are open on the ground for maximum cooling and are adjusted in-air to manage engine temperature for optimal performance.

Step-by-step explanation:

Oil cooler flaps are components typically found on aircraft engines that help regulate the temperature of the engine oil. On the ground, the oil cooler flaps are usually open to maximize airflow and the cooling effect on the stationary or slow-moving aircraft engine.

In the air, however, the oil cooler flaps can be adjusted to manage the engine temperature, which means they could be partially open or closed depending on the cooling needs of the engine during flight. The proper management of oil temperature is critical for optimal engine performance and longevity.
