Eye movements during daytime collision avoidance scanning should
A
not exceed 10 degrees and view each sector at least 1 second.✓ Correct Answer
B
be 30 degrees and view each sector at least 3 seconds.
C
use peripheral vision by scanning small sectors and utilizing off-center viewing.
Explanation
AIM 8-1-6 describes daytime scanning as a series of short, regularly spaced eye movements that bring successive areas of the sky into central (foveal) vision. Each movement should not exceed 10 degrees, and each area should be observed for at least 1 second so that targets can be detected. Thirty-degree sweeps are too wide for the narrow foveal field. Off-center viewing is the technique for night vision, not daytime scanning.
