In-flight Fire

Fire in the air is one of the most hazardous situations that a flight crew can be faced with. Without aggressive intervention by the flight crew, a fire on board an aircraft can lead to the catastrophic loss of that aircraft within a very short space of
time. Once a fire has become established, it is unlikely that the crew will be able to extinguish it. Time is critical and the crew must land the aircraft as soon as possible.

Types of Fire

Engine Fire. An engine fire can normally be detected and contained by the aircraft fire detection and suppression systems. However, in certain circumstances (e.g. an explosive break up of the turbine), the nature of the fire is such that on- board systems may not be able to contain the fire and it may spread to the wing or fuselage. Where an engine fire has been successfully contained, there is still a risk that the fire may reignite and therefore it is still advisable for the crew to land the aircraft as soon as possible and allow fire crews to carry out a visual examination of the engine.
Wing Fire. Most modern aircraft carry the majority of their fuel in wing tanks. If those fuel tanks or the associated pipes leak, or they are damaged, and fuel comes into contact with an ignition source, then fire can break out within, on, or under the wing.
Cabin Fire. A fire within the cabin will usually be detected early and be con- tained by the crew using onboard fire fighting equipment. As with an engine fire, it is still advisable to land the aircraft as soon as possible and carry out a detailed examination of the cause of the fire and any damage.
Hidden Fires. A hidden fire may be detected by onboard fire detection systems or by the crew or passengers noticing smoke or fumes, a hot spot on a wall or floor, or by unusual electrical malfunctions. This is the most dangerous type of fire be- cause they are difficult to locate and access in order to fight them. The time delay may allow the fire to spread and do considerable damage to the aircraft.
