    completely cover an exposed surface regardless of duration. Visibility is not affected. 2. Moderate. Slow accumulation on ground. Visibility reduced by ice pellets to less than 7 statute miles. 3. Heavy. Rapid accumulation on ground. Visibility reduced by ice pellets…

  • Chapter 7. Safety of Flight › Section 6. Potential Flight Hazards › 7-6-16. Avoid Flight in the Vicinity of Exhaust Plumes (Smoke Stacks and Cooling Towers)

    Exhaust Plumes (Smoke Stacks and Cooling Towers) a. Flight Hazards Exist Around Exhaust Plumes. Exhaust plumes are defined as visible or invisible emissions from power plants, industrial production facilities, or other industrial systems that release large amounts of vertically directed ... disturbances such as turbulence and vertical shear. Other identified potential hazards include, but are not necessarily limited to: reduced visibility, oxygen depletion, engine particulate contamination, exposure to gaseous oxides, and/or icing. Results of encountering a plume may include airframe damage…
