According to the METAR report, what is the anticipated holdover time if using Type I de-ice fluid?

The anticipated holdover time when using Type I de-ice fluid is important for determining how long the deicing process will be effective in preventing the accumulation of ice, snow, or frost on the aircraft surfaces. Type I fluids are typically heated and have a lower viscosity, allowing them to flow over the aircraft and remove ice or snow effectively.

The holdover time is influenced by several factors including the type of precipitation, temperature, and wind conditions. Option B indicates a holdover time of 0...11 to 0...18, which aligns with typical operational guidelines and charts provided by manufacturers and regulating bodies. This window suggests that after application, the Type I de-ice fluid can effectively protect the aircraft from icing for 11 to 18 minutes under certain conditions.

Choosing this option reflects an understanding of standard de-icing protocols and the properties of Type I fluid, which is designed for quick removal but requires timely follow-up to maintain the aircraft in a safe, ice-free condition.
