The recommended scanning method for collision avoidance during nighttime flights involves utilizing peripheral vision by scanning small sectors and employing off-center viewing. This technique is crucial because it allows a pilot to take in a broader visual field without fixating on a single point, which can lead to delayed reaction times if an obstacle or other aircraft suddenly appears.

During night flying, visibility is significantly reduced, making it more challenging to detect other aircraft. By using peripheral vision, the pilot can maximize their awareness of the surroundings. Scanning small sectors helps in systematically covering an area rather than attempting to absorb everything at once. Off-center viewing further aids in detecting objects that might not be directly ahead, ensuring that potential threats are noticed before they become critical.

Relying on high beams or navigation lights alone can be insufficient. High beams do not penetrate darkness well and can create glare for the pilot, while navigation lights are primarily for indicating the presence of an aircraft but do not enhance the overall visibility of the environment. Continuously monitoring instruments, while important for overall flight management, does not actively assist in collision avoidance in the same manner as effective visual scanning does. Thus, employing the recommended scanning method helps maintain safety and situational awareness during nighttime operations.
