CARBURETTOR SYSTEM
CARBURETTOR SYSTEM What is it? The Carburettor System is an aircraft system that controls and supplies spark-ignition type aircraft with a mixture of fuel when it is idling, accelerating, put to a halt, or for power enrichment systems (FAA, 2016). Figure 1. A Float-type carburetor. Problem A potential failure that could happen with this system is the formation of ice within the system. Identification The identification of icing varies with aircraft type: The signs of carburetor icing in a fixed-pitch propeller aircraft is usually a decrease in Revolutions Per Minute (RPM) followed by engine roughness. A pilot flying an aircraft with a constant-speed propeller will notice a decrease in manifold pressure instead of an rpm reduction. If an exhaust gas temperature gauge is fitted on an aircraft, it would also very likely display a decrease in temperature. In steady level flights, such a decrease in temperatures may be detected before any sign...
