Adhering to procedures and keeping tight control of fluid blending, fluid temperatures etc. has long been a natural part of your daily work in aircraft de-icing and warrants that the aircraft will be sprayed and treated as required. And when spraying an aircraft flight safety is your foremost concern - getting the ice and snow completely off the wings and fuselage of the aircrafts coming in for de-/anti-icing sprays.

Winter weather however is not so easily controlled and you may occasionally have found yourself in situations wanting to have a more precise picture of the actual precipitation condition - especially when preparing for changes. Questions such as: "What is the best choice of fluid under these conditions to get the aircraft safely off the ground" may have popped up, and in severe conditions such as an ice storm where you have experienced difficulties in keeping up removing the amount of precipitation falling on the aircraft, you may have wondered how quickly the aircraft had to get off the ground before the fluid sprayed would stop protecting the aircraft.

This is where you will benefit from DIIS. It enables you to get an accurate picture every 15 minutes or less providing you with a scientific calculation of the Hold Over Time corresponding to the actual weather situation and selected de-/anti-icing fluid. Compare that to the que on the taxiway and you have a planning and decision support tool that also will take the load off your shoulders.

Additionally your customers, the airlines, are focusing heavily on cost savings throughout the entire chain. This has prompted business models to change from paying per the litre to offering bonuses for achieved cost savings. In that case you will also benefit from using the DIIS in cooperation with the pilots. Field studies have shown that up to 80% of anti-icing operations could potentially be avoided.

Finally, you may also feel happy about the fact that reduction in anti-icing fluid helps reduce contamination of airport environment and water resources. De-icing fluid is not an environmentally friendly agent and great effort is spent to minimize the damage produced by the waste of de-icing fluid. Optimization of de-icing decisions will thus also help reduce the environmental cost factor.
