What is the most effective way to use the eyes during night flight?
A
Look only at far away, dim lights.
B
Scan slowly to permit offcenter viewing.✓ Correct Answer
C
Concentrate directly on each object for a few seconds.
Explanation
At night the cone cells in the center of the eye work poorly, leaving a night blind spot; PHAK Chapter 17 recommends scanning slowly and looking about 5 to 10 degrees off center so the rods can detect objects. Staring directly at an object makes it fade, and looking only at far-away lights is not a scanning technique.
