Which method is best for scanning for other aircraft during daylight hours?

The method of utilizing a series of short eye movements within a 10-degree range is particularly effective for scanning for other aircraft during daylight hours. This technique allows pilots to maintain a focused and systematic observation of the cockpit and external environment. By engaging in short eye movements, pilots can effectively scan their surroundings without losing situational awareness, and they can quickly identify potential threats or nearby aircraft.

In bright daylight conditions, where the visibility of other aircraft may be reduced, fine-tuned visual scanning is critical. The short eye movements enable quick assessment of the nearby airspace while minimizing the risk of missed visual cues, as they allow for comprehensive coverage of the field of view. Moreover, this method helps prevent visual fatigue that can occur with prolonged fixed gazes or overly broad sweeping movements, maintaining alertness and responsiveness to dynamic aviation scenarios.
