Calibrating a de-icing fluid mixing system is critical to ensure the correct concentration ratio of de-icing fluid to water, which directly affects its effectiveness. The first step is to consult the fluid manufacturer's recommendations and the aircraft's de-icing procedures to determine the required concentration ratio for the specific weather conditions and aircraft type. Common ratios include 50/50, 75/25, or 100/0 (undiluted fluid). Next, locate the calibration points on the mixing system. These are typically valves or adjustments that control the flow rates of the de-icing fluid concentrate and water. Prepare a calibrated container to collect the mixed fluid. Sta....
