Grading Items

- Sunset to sunrise, aircraft must have position lights (FAR 91.209)
- Anticollision lights (prior to 8/11/71) (FAR 91.205)
- Landing light - if operated for hire (FAR 91.205)
- Electrical supply
- Spare fuses
- Airport beacons

Runway Incursion Avoidance
Night Local Orientation
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
Night Approach and Landing
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
