The Carburettor Temperature Probe (CRB) is used to detect temperature drop in the carburettor.

For successful ignition to occur, the air-fuel mixture has to be perfect and this can only happen at the right temperature. Now when fuel and air is mixed, the temperature inside the carb will drop dramatically and this is compounded due to external cold air and cold temperatures. Next thing you know – the carburettor is frozen solid – and this is not something you want to happen when flying; not by a long shot.

So, the carburettor is kept warm and steady at its ideal temperature through a rather ingenious way by installing an anti-icing syst ... Read more »
