Is it an engine or a tailpipe fire?? types of fires?? For training purposes only.

Actual engine fires are a rare occurrence. A fire affecting an engine may be the result of different malfunctions and may have different origins. Thus, a fire affecting the engine should be dealt with according to the origin of this fire. Two different types of fire may affect the engine and the procedures for fire fighting should be adapted according to each type of fire: The engine (or nacelle) fire OR The tail pipe fire. From the cockpit, it is not always obvious for flight crews to differentiate these two kinds of fire. This is particularly true in this unusual and stressing situation with the engine belching smoke and flames. This is not specific to a given type of engine or even to a type of aircraft, but experience shows that flight crews may tend to discharge the fire extinguisher bottles in case of a reported tail pipe fire. This presentation aims at describing the main differences between an engine fire, also called an external fire since it mainly affects the nacelle compartment, and a tail pipe fire, also called an internal fire since the fire is developing within the engine core. This video also highlights the importance of always applying the relevant strategy for fire fighting depending on each type of fire. An engine fire is an external fire. This is a ground or an in-flight event. It is due to a malfunction of an external component with possible continuous feeding of the fire. When occurs the ENGINE FIRE warning is triggered and nacelle temperature rises. The appropriate crew procedure is to shutoff the fuel supply, isolate the engine and, if necessary, discharge the fire extinguishing agent. A tail pipe fire is an internal fire that is contained within the engine. This is a ground event normally at engine start or shutdown. It is due to an excess of fuel in the combustion chamber or in the turbine. It does not trigger any warning and is visually detected. It is accompanied with a rapid EGT rise. The appropriate crew procedure is to shutoff fuel and ignition and to dry motor the engine for ventilation. The ground fire extinguisher should be used as a last resort.
