  4. Percentage of Laser Illuminations by Month Type of Flight

  5. Percentage of Laser Illuminations by Time of Day Note: Laser Illuminations occur most frequently from 6:30 – 11:30 p.m.

  6. FAA Order 7400.2 was revised to establish zones of navigable airspace around airports to protect flight crewmembers from temporary visual impairment during critical flight operations.

  7. FAA Order 7400.2 FLIGHT ZONES

  8. FAA Order 7400.2 FLIGHT ZONES

  9. FAA 737 Flight Simulator Kodak DC240, aperture f/2.8, shutter speed 1/6 s

  10. Irradiance level: 0.5 µW/cm2 Simulates the effect of a 5 mW green laser pointer as seen from 3,000 feet away, or a 300 mW laser from 16,000 feet away

  11. Irradiance level: 5 µW/cm2 Simulates the effect of a 5 mW green laser pointer as seen from 1,000 feet away, or a 300 mW laser from 6,700 feet away

  12. Irradiance level: 50 µW/cm2 Simulates the effect of a 5 mW green laser pointer as seen from 330 feet away, or a 300 mW laser from 2,400 feet away

  13. Fly Safely!
