What is the de-icing system limitation in freezing weather?

The limitation regarding the de-icing system in freezing weather emphasizes that the fluid used for de-icing must remain within an effective temperature range to function properly. This is crucial because the properties of the de-icing fluid can change dramatically at extreme temperatures. If the fluid is not within this temperature range, it may not effectively prevent ice or snow from adhering to the surface, leading to potential safety hazards.

Maintaining the right temperature ensures that the de-icer can spread evenly and adhere appropriately to surfaces, providing the necessary protection against freezing conditions. Understanding this limitation allows operators to effectively use de-icing systems, ensuring safer travel and operations in adverse weather.
