The Hazards of the Winter Season

"The perennial perils of winter weather are upon us once again. Seasonal weather, consisting of low temperatures and visibilities, freezing rain, ice, drizzle, snow, and fog, brings many additional challenges to flight operations. Hazards exist everywhere, and may not be clearly evident. Degrading conditions, changing schedules, unpredictable situations, complex procedures, ambiguity, confusion, task saturation, and fatigue can all increase the seasonal risk" The attached Callback Newsletter contains narratives on valuable lessons learned.
