===== Grading Items =====

  * [[siu:tomato_flames|Aircraft & Airport Lighting for Night Ops]]

  * Runway Incursion Avoidance

  * Physiological Aspects of Night Flight
  * Visual Scanning Techniques and Considerations
  * Night Visual Illusions
    * Distant stationary lights can be mistaken for stars or other aircraft
    * Cloud layers or even the northern lights can confuse a pilot and indicate a false visual horizon. 
    * A black-hole approach occurs when the landing is made from over water or non-lighted terrain where the runway lights are the only source of light
    * Bright runway and approach lighting systems, especially where few lights illuminate the surrounding terrain, may create the illusion of being lower or having less distance to the runway

  * Spatial Disorientation, Motion Sickness and Inflight Illusions
  * Hypoxia, Hyperventilation, and Carbon Monoxide Poisoning
    * Hypoxia - Lack of oxygen to the tissues
      * Remedy by using supplemental O2
    * Hyperventiliation - Too little CO2 in the blood
      * Remedy by breathing into a bag, talking, or slowing breathing rate
    * Carbon Monoxide Poisoning - Susceptibility increases as altitude increases
  * Middle Ear and Sinus Problems
  * Stress, Fatigue, and Dehydration

<note important>Dark adaptation is impaired by exposure cabin pressure altitudes above 5,000 ft, carbon monoxide, deficiency of vitamin A, and by prolonged exposure to direct sunlight.</note>
