Safety is one of the most important objectives in aviation industry; therefore de-icing an aircraft plays a crucial role during cold months. Specialists must be well educated on the de-icing process as it leads to comfort and safe flight of pilots and passengers. This article will help you to investigate the importance of ice removing process and to be familiar with fluid mixtures which are used to de-ice an aircraft.
Why is removing the ice and snow build up so important?
A plane’s wings and rear tail are engineered with a very specific shape in order to provide proper lift for flight. Any change in their shape can cause crucial issues during take-off. If the snow or ice disrupts the flow of airflow, it could hinder the ability to lift the aircraft. Deicing isn’t just about the wings and tail either. The spray is also focused on the nose, where radar equipment sits.
What is used to de-ice the plane?
Deicing fluid is a mixture of heated chemical called propylene glycol and water. It is sprayed on hot (150 to 180 degree) at high pressure to melt or remove ice and snow. There are a few types of fluids used, but most common is Type I and Type IV. Type I fluid is applied to the aircraft to remove the snow and ice. Type IV is fluid is then applied to anti-ice the plane.
Do anti-icing fluids lose effectiveness in flight?
On most jet aircraft, hot air from the engines is routed through piping in the wings, tail and engine openings to heat their surfaces and prevent icing. Pilots have to be extremely cautious at high altitudes to not run into “icy clouds” or climates. Even airliners can occasionally encounter conditions that call for a speedy decent to warmer air.
