**Core Concept**
The pilot's behavior is an example of a defense mechanism, a psychological process that helps individuals cope with stress, anxiety, or other uncomfortable emotions. This specific defense mechanism involves redirecting attention away from anxiety-provoking thoughts or situations by focusing on a more manageable or familiar aspect, in this case, the technical details of the engine malfunction.

**Why the Correct Answer is Right**
By explaining the technical details of the engine malfunction, the pilot is using **intellectualization** as a defense mechanism. Intellectualization involves rationalizing or analyzing a situation in an overly objective or detached manner, often to avoid feelings of anxiety or fear. This defense mechanism allows the pilot to momentarily shift his attention away from the impending crisis and focus on a more controllable aspect, thereby reducing feelings of anxiety. This may give him a sense of temporary control and calm, allowing him to momentarily put aside his fear of the impending crash.
