What we do


Holdover Time Science 101


Holdover Time Tables


✈ 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

Fluid Testing


✈ 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



✈ 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

NO HOTs EXIST

✈ 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


✈ 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



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

Applications


Web Portals


Benefits

Improved operational planning for airports, carriers and service providers

Enhanced ATC processes within A-CDM

More frequent winter weather information for winter flight planning More accurate identification of de/anti-icing conditions Better identification of changing weather

Accurate determination of fluid holdover times Enable better fluid selection Enable expanded use of current holdover time information Expanded holdover times for all fluids, including Type I Reduction of human factor involvement in holdover time

assessment Reduction of departures with exceeded fluid holdover times

Economic Savings

Benefits


Reduced costs of fluids and recovery/ recycling

Source Reduction of Glycol Reduction of environmental impacts and costs

Operational Improvement Airport throughput Time management

Airport Implications Runway maintenance Application of runway de/anti-icers

Benefits


Transport Canada issued regulatory approval process for LWE systems in December 2007 (Exemption from CAR 602.11)

SureWx completed operational assessment with WestJet 2008-10, and began commercial service in 2010

FAA initiated Ops Demo for LWE systems in advance of winter 2013-14

SureWx Ops Demo partner is FedEx
