What are the two types of light sensitive cells?
Cones and Rods
What are Cones?
Responsible for color, detail, far away objects; located in the center of the retina.
What are Rods?
Peripheral vision and provide vision in dim light; located in a ring around the cones.
What does night vision mainly use, Rods or Cones?
Rods because Cones need light to function.
, What should you do about cockpit lighting at night?
Minimum brightness allows reading of the instruments without hindering outside vision.
What should you do to combat disorientation and illusions?
Cross Check Instruments
What is Autokinesis?
Staring at a light with a dark background and the light appears to move on its own. To prevent
this, avoid fixating.
What is Reversible Perspective Illusion?
At night, an aircraft may appear to be moving away when it is approaching. If the light intensity
increases, the aircraft is approaching, if it dims its moving away.
Size-Distance Illusion?
Light that is getting brighter or dimmer, may be interpreted as approaching or retreating.
What is Flicker Vertigo?
A light flickering between 4 and 20 cycles per second produces unpleasant and dangerous
reactions. Can cause nausea, vomiting and vertigo.
