Read the following technical briefing:
During winter flight operations, ground crews apply specialized deicing and anti-icing fluids to ensure aerodynamic safety. Type I deicing fluid, applied heated to melt accumulated snow, provides a maximum holdover protection time of 15 minutes in light freezing drizzle. For prolonged ground delays in freezing precipitation, crews apply Type II fluid, which maintains an effective holdover duration of 45 minutes. For severe winter conditions with heavy freezing rain, advanced Type IV fluid is utilized, delivering up to 80 minutes of surface protection. Meanwhile, standard Type III fluid is reserved for commuter aircraft with rotation speeds below 100 knots.
Based on the technical briefing above, match each aircraft fluid type with its correct operational quantitative specification.
- Type I fluid15 minutes maximum holdover protection
- Type II fluid45 minutes effective holdover duration
- Type III fluidRotation speeds below 100 knots
- Type IV fluidUp to 80 minutes of surface protection
