What should be the priority when applying de-icing fluid under windy conditions?

When applying de-icing fluid under windy conditions, ensuring proper coverage on all surfaces is crucial. Wind can significantly impact the way de-icing fluid is distributed, causing it to drift away from the target areas. If the coverage is insufficient, certain portions of the aircraft may remain untreated, which can compromise safety by leaving ice or snow on critical surfaces. Proper coverage means that the fluid must reach all areas, including wings, tail, and control surfaces, to ensure effective de-icing.

In windy conditions, if the focus were instead on maximizing fluid usage, there could be unnecessary waste, as much of the fluid might be blown away before it can adhere to the surfaces effectively. Likewise, directing fluid into low-pressure areas wouldn't address the need for comprehensive coverage across all surfaces which are essential for proper de-icing. Additionally, while avoiding over-application is important for cost efficiency and environmental considerations, the priority in windy conditions must be on achieving uniform application to ensure safety and operational effectiveness.
