Flameout is when a jet engine’s flame goes out, causing the engine to fail. Multiple engines provide redundancy, and autopilot systems monitor engine functions. Causes of flameout include mechanical clogging, fuel mixture, physical damage, and bad weather. Safety systems stabilize the aircraft, and investigators evaluate accidents to prevent future incidents.
Flameout is the failure of the jet engine when the flame that normally burns continuously during operation goes out. Without heat from the flame, the engine can no longer provide propulsion. The aircraft will not fall out of the sky immediately when a fire occurs, but it can pose a risk if not addressed. It is usually possible to restart the engine and restore functionality.
Aircraft powered by jet engines often have multiple engines to create not only more power, but also some redundancy. In the event that one engine experiences a fire, a situation that can occur in a variety of circumstances, the other engines can compensate. Once the pilot restores function to the failed engine, the aircraft can stabilize and continue flight. Autopilot systems monitor engine functions and can alert pilots to problems, as well as perform the necessary calculations to keep an aircraft in check when one or more engines fail.
The jets rely on a continuous combustion flame to function as air and fuel move through the engine. In a fire, he dies, and the pilot must restart the engine to get the flame going again. One possible reason for this is mechanical clogging in the engine, usually caused by contact with a foreign object such as a bird or volcanic ash. The air/fuel mixture can also be a culprit, as too much fuel can put out the flame. Physical damage can be another problem, as can inadequate oxygen supplies.
Bad weather is a common cause of burns. Severe rain, snow, and ice can put out an engine’s flame, even with a protective cover and other measures intended to limit exposure to the elements. This is a particularly high risk when the engines are operating at low speeds, as can occur during descent or once an aircraft reaches cruising altitude. During these periods of flight, pilots remain alert for the first warning signs of trouble with their engines so that they can take appropriate evasive action if necessary.
In the event of a fire, the safety systems are activated to stabilize the aircraft as much as possible. Sometimes it is not possible to restart the engine and the plane may need to make an emergency landing with the remaining engines. Other instances, such as those involving multiple engine failures or problems with other systems on the plane, can lead to failure. After an accident, investigators carefully evaluate all available material to determine what happened and look for possible methods to prevent such incidents in the future.
