4. Holdover Time Science 101 WEATHER SOLUTIONS AND OPERATIONAL SUPPORT SYSTEMS

5. Holdover Time Tables WEATHER SOLUTIONS AND OPERATIONAL SUPPORT SYSTEMS

6. ✈ De/anti-icing fluid holdover times are an important tool in the safety of winter flight operations ✈ Significant amount of research and development was performed and the quality of the data employed in the current holdover time tables is excellent Holdover Time Science 101 Wx SOLUTIONS AND OPERATIONAL SUPPORT SYSTEMS WEATHER SOLUTIONS AND OPERATIONAL SUPPORT SYSTEMS

7. Fluid Testing WEATHER SOLUTIONS AND OPERATIONAL SUPPORT SYSTEMS

8. ✈ The holdover time for any aircraft de/anti-icing fluid is a function of three variables: ✈ Rate of precipitation (LWE) ✈ Type of precipitation ✈ Ambient temperature Holdover Time Tables WEATHER SOLUTIONS AND OPERATIONAL SUPPORT SYSTEMS

9. ✈ The holdover time for any aircraft de/anti-icing fluid is a function of three variables: ✈ Rate of precipitation (LWE) = ? ✈ Type of precipitation = Snow ✈ Ambient temperature = -4 Celsius 0:40 – 1:05 Holdover Time Tables WEATHER SOLUTIONS AND OPERATIONAL SUPPORT SYSTEMS

10. Rate of 7 g/dm2/h = 1:20 HOT Rate of 17 g/dm2/h = 0:50 HOT Rate of 40 g/dm2/h = 0:31 HOT HOT RANGE 0:40 to 1:05 LIGHT SNOW MODERATE SNOWHEAVY SNOW -4.3C -14C Holdover Time Science 101 NO HOTs EXIST

11. ✈ Flight crew’s ability to extract the proper information from the tables has not advanced with the science employed to build the tables ✈ Refinement of the “format” would allow for expansion of operational use of fluid holder times Holdover Times WEATHER SOLUTIONS AND OPERATIONAL SUPPORT SYSTEMS

12. ✈ System consists of numerous sensors enabling the determination of: ✈ Rate of precipitation ✈ Type of precipitation ✈ Ambient temperature ✈ System measurements used to generate an accurate holdover time (HOT) for each departing aircraft based actual conditions ✈ System output can be configured to generate HOT information according to the client’s preference and operational needs WEATHER SOLUTIONS AND OPERATIONAL SUPPORT SYSTEMS

13.  All data from the sensor units in the field are transmitted via cellular network to the SureWx central server
