Final answer:
A remote pilot should systematically focus on different segments of the sky for short intervals to effectively scan for traffic, similar to how radar is used by air traffic controllers in low visibility conditions.
Step-by-step explanation:
To scan for traffic as a remote pilot, the technique that should be used is to systematically focus on different segments of the sky for short intervals. This method helps in detecting both stationary and moving objects by using a block-by-block approach, which can be more effective than a continuous scan or solely relying on peripheral vision. This block-by-block method ensures a thorough surveillance of the entire sky, similar to how air traffic controllers may use radar instruments to detect aircraft in poor visibility conditions due to weather. A sound scanning strategy incorporates periods of focused attention and scanning different areas methodically while considering factors like the time of day, variations in traffic patterns, and types of aircraft in the vicinity.
