This video shows a Norwegian Boeing 737-800 undergoing de-icing before departure, a critical winter operation in cold-weather aviation. De-icing is performed when ice, snow, or frost accumulates on the aircraft’s surfaces, especially the wings, which can severely affect lift and aircraft performance. A specialized de-icing truck is positioned next to the wing, spraying heated de-icing fluid, typically a glycol-based mixture, onto the wing surface. The yellowish color visible on the wing comes from the fluid, which is designed to melt existing ice and prevent new ice from forming for a limited time.

The bright lights mounted on the de-icing vehicle allow technicians to clearly inspect the wing, ensuring all contamination is removed, even in low-light conditions such as early morning or evening. De-icing focuses on critical aerodynamic surfaces like wings, control surfaces, and sometimes the fuselage and tail. This process is closely monitored and follows strict procedures regulated by aviation authorities.

The background suggests a cold, possibly snowy environment, common at Scandinavian airports, where winter operations are routine. De-icing is mandatory before takeoff whenever contamination is present, as even a thin layer of ice can drastically reduce lift and increase drag. This video highlights the importance of ground safety procedures and teamwork in ensuring a safe and smooth departure in challenging weather conditions.
