Adequate Nighttime Flood Lighting

54.  Deicing an aircraft in a dimly lit, low visibility environment can be both difficult and unsafe. The ability to enter and exit the deicing area safely is hampered, especially at night when conditions like blowing snow has reduced visibility. The lighting should be sufficiently bright to allow for "day like" operations to take place. Nighttime lighting should be shielded to prevent glare for pilots of aircraft taxiing, landing or taking off in close proximity to the deicing facility.

55.  Good flood lighting, whether it is permanently fixed, portable or vehicle mounted, should be installed in consideration of the following points:

• Adequate nighttime lighting at the deicing facility will allow pilots to see clearly and therefore follow the hand signals of the Deicing Operator.
   
• Deicing crews will require sufficient nighttime flood lighting to enable them to provide the best possible deicing/anti-icing treatment.
   
• Pilots will also need a well lit environment within which to conduct a pre-take-off contamination inspection.
