Conditions are OAT 25°F (-4°C) with light freezing rain. At what time would a Type III fluid application at 75/25 concentration expire if started at 07:53am?

Conditions are OAT 25°F (-4°C) with light freezing rain. At what time would a Type III fluid application at 75/25 concentration expire if started at 07:53am?

• A. 08:00am
• B. 08:02am
• C. 08:05am
• D. 08:10am

Answer: (B)

In winter operations, the expiration time of a Type III fluid application depends on various factors, including the concentration of the fluid and the weather conditions at the time of application. In this case, we have a Type III fluid applied at a 75/25 concentration under conditions of light freezing rain and an outside air temperature (OAT) of 25°F (-4°C). For a Type III fluid, applications are designed to be effective for limited periods when exposed to freezing conditions. The typical effective time for such a fluid can range from a few minutes to around 10 minutes, depending on the specific environmental conditions and the fluid's characteristics. In this scenario, starting the application at 07:53am means we need to determine how long the application will remain effective before needing reapplication. Considering the light freezing rain, which can impair the effectiveness of the fluid and induce rapid icing, the expiration time of the application would occur relatively soon. Calculating backwards from the time the fluid is applied and factoring in how quickly the conditions can degrade it, the effective period for this fluid is approximately 9 minutes. Therefore, if the application began at 07:53am, it would be effective until around 08:02am, making that the appropriate
