The trains will spray anti-icing fluid
on tracks and are also fitted with hot air blowers and steam jets.
Citing severe winter weather, the airline halted services in Chicago and "proactively" canceled about 220 flights after realizing it wouldn't have enough anti-icing fluid
to safely operate the rest of the day, according to a statement from Southwest.
Network Rail says it has various ways to try to keep the tracks clear, including: specialist snow and ice treatment trains (which come with hot-air blowers, steam jets, brushes, scrapers, heated anti-freeze jets and compressed air), passenger trains fitted with snowploughs, dedicated snowplough trains, anti-icing fluid
and heating strips fitted directly to the tracks, and heaters and insulation on the points--to name but a few.
aACAo40% reduction of anti-icing fluid
usage in 2014aACAo2016.
To resist later inflight ice accumulation, the de-icer boots need to be wiped down with an approved anti-icing fluid
. Pitot heat, windshield heat and propeller heat should also be checked carefully, following POH procedures.
Guidelines are also provided for holdover time, which is the time from when de-or anti-icing fluid
is applied to when it begins to fail, and snow or ice accumulates." Mr Ellis pointed out it is essential that the correct ratio of inhibited glycol fluid to water is calculated to enable optimum performance of de/anti-icing fluids.
Approximately one fifth of ANAs annual winter tonnage of de-icing and anti-icing fluid
is DF-Sustain, supporting important sustainable improvements and the airline and airport's wider environmental strategies at the main gateway to the city of Hokkaido.
As well as being used cold as an anti-icing fluid
to protect aircraft surfaces against the build-up of frost, ice and snow, ABC-K Plus can be applied hot, as a one-step de- and anti-icing solution, and the fluid's handling characteristics have also been optimised for effectiveness of lift.
Using a sustainable glycol for something as frequently applied as de- and anti-icing fluid
will have a dramatic and immediate impact on aviation's carbon footprint and greenhouse gas emissions.
