Delta Air Lines crews de-ice an aircraft set to depart for Salt Lake City at St. Louis Lambert International Airport on January 17, 2020.

A winter storm bound for St. Louis on Friday had a forecast with a full mix of precipitation types: snow, sleet, freezing rain, and rain. St. Louis Lambert International Airport crews were in full force in advance of the first wave making sure the airfield got a full sweep of liquid de-icer for runways, taxiways and ramp areas around the gates. Airline crews were also prepared with de-icing teams dispatched throughout the day to treat each aircraft before departure when needed based on temperatures, precipitation and other factors. De-icing is a priority in cold weather or during winter weather events. Snow, slush or ice on aircraft are safety concerns because it can drastically reduce wing lift upon takeoff. Airline crews have set procedures for spraying de-icing fluids on critical parts of the aircraft, including the top of the fuselage, the wings and horizontal stabilizers. The process adds time between boarding and takeoff, but it’s critical for safety during whatever winter throws our way.
