• Increased risk of _____ in aircraft movement areas

Wind shift, foreign object debris (FOD)

Airport-related conditions affected by wind:

stronger, turbulence

Name 3 impacts icing can have on aircraft and airport operations

Affect the aerodynamic performance of aircraft, de-icing delays, reduced traffic volumes
