“Disruptive” deicing fluid
"Affected by the cold wave weather and snow and ice, some inbound and outbound flights at the airport are delayed or cancelled, reminding the majority of passengers to adjust their travel plans", whenever they encounter winter snow, passengers can always hear such a voice broadcast when waiting for the plane.
However, flight delays often do not last too long, which is inseparable from the airport's "18 skills" under the snow and ice protection operation, the purpose is to ensure the normal takeoff and landing of flights in special weather and the safe travel of passengers.
Under icy conditions, ice, snow and frost will have a direct impact on the safety of the operation of the aircraft, which will make the outer surface of the aircraft rough, increase the weight of the aircraft, limit the activity range of the aircraft control surface, lead to instrument errors, and in serious cases, also cause the increase of the aircraft stall and the abnormal elevation of the moment, thus greatly reducing the flight performance of the aircraft, especially when the aircraft takes off and rises. It makes the flight attitude difficult to control, and even causes air crashes. There have been many air accidents caused by bad ice and snow weather in the world aviation history, flight crew, maintenance and dispatch personnel should pay great attention to the harm brought by winter weather conditions to aircraft. Therefore, in order to ensure normal shipping and flight safety, it is necessary to remove frost and snow on the surface of the aircraft.
