What specific information should be included in a post-deicing report submitted to the flight crew?

The post-deicing report submitted to the flight crew is a crucial document that provides essential information for making safe takeoff decisions. The report must include the time the de-icing/anti-icing process was completed. This is the most important piece of information, as it establishes the starting point for holdover time calculations. The report also needs to state the type of fluid used (e.g., Type I, Type IV). Different fluid types have different holdover times, so this information is critical for the flight crew to determine how long the aircraft is protected. The concentration of the fluid mixture (e.g., 50/50, 75/25) is essential, along with the fluid's brand name or product code. Holdover times are dependent on concentration and fluid type. The report should also state the prevailing weather conditions at the time of de-icing/anti-icing, including the temperature, wind speed and direction, and precipitation type and intensity. These conditions affect holdover times. The post-deicing report needs to specify which aircraft surfaces were treated (e.g., wings, tail, fuselage). This ensures that the flight crew knows which surfaces are protected. Any pre-de-icing contamination observed, such as the type and amount of ice, snow, or frost that was removed, is essential information. This gives the flight crew context for the de-icing operation. The report should clearly state that a post-application check was performed and that the aircraft surfaces were free of contamination at the completion of the process. The name and signature (or employee number) of the person who performed the de-icing/anti-icing and completed the report is necessary for accountability. Any relevant remarks or observations, such as unusual weather conditions or equipment malfunctions, should be included in the report. The post-deicing report should be presented to the flight crew in a clear and concise manner. The information should be easily understood and readily accessible. Accurate and complete information in the post-deicing report is crucial for flight safety. The flight crew relies on this information to make informed decisions about takeoff timing and procedures. It is important to note that some airlines and airports may have specific forms or procedures for post-deicing reporting.
