There are many parts and components in an aircraft that do not generate their own heat and instead, rely on heat generated from the engine. Of all these non-heat-generating components or parts, the aircraft carburettor is perhaps the most vulnerable to humidity and low temperatures. The freezing of the aircraft carburettor would not just impede the smooth functioning of the engine, it will ultimately stop the engine from functioning!

To prevent the above from happening, an anti-icing system that preheats the air before it reaches the carburettor is put in place. This is intended to keep the fuel-air mixture warm enough so that freezing does not occur and ... Read more »
