Operations & SafetyQuestion 97 of 100
Which visual technique best helps a remote pilot and VO see the aircraft and other traffic during a night operation?
a.Stare steadily at the aircraft's position light without shifting the eyes
b.Sweep the sky with a bright white flashlight every few minutes
c.Look slightly off-center of an object and allow about 30 minutes to adapt
d.Wear dark sunglasses so that nearby ground lighting cannot cause glare
Explanation
At night the center of the eye is least sensitive, so off-center (peripheral) viewing plus roughly 30 minutes of dark adaptation gives the best chance of seeing dim objects. Staring at one point causes the image to fade, and a bright flashlight or any white light destroys the adaptation you spent 30 minutes building. Dark sunglasses reduce the light reaching the eye and make night detection worse, not better.
