Can a plane drop an engine?
Flying at a typical altitude of 36,000 feet (about seven miles), an aircraft that loses both engines will be able to travel for another 70 miles before reaching the ground. Smith continues: “Total engine loss is about as probable as a flight attendant volunteering to give you a shoe-shine, though it has happened.
Can airliners jettison engines?
Some models, such as the 777 and some 767 airplanes have a fuel jettison system installed, but it is not required by FAR. An overweight landing with an engine inoperative or a system failure may be less desirable than landing below maximum landing weight.
Why do jet engines catch on fire?
A drop in fuel pressure or a fluctuating fuel pressure reading may suggest a broken fuel line — a common precursor to an engine fire. A rough-running engine might be caused by a cracked cylinder, which can leak oil or hot gas and ignite a blaze.
What does it mean when an engine is on fire?
A major issue is that it’s not really the engine itself which is on fire, in fact they are supposed to be on fire in a sense. In many cases an engine fire really means that you have lost control of the fuel/hydraulic fluid flow to the engine. For example if a turbine blade detaches, penetrates the engine casing and cuts a fuel or hydraulic line.
What causes a rough running engine to catch fire?
A rough-running engine might be caused by a cracked cylinder, which can leak oil or hot gas and ignite a blaze. Black smoke usually signals an oil fire, and fuel usually burns bright orange. By the time you get the “hot-foot” symptom, the fire is already blazing on the other side of the firewall.
Why is dropping an engine a bad idea?
There are many more reasons why dropping engines is a bad idea. Some designs allow an engine to shear away from the wing in the event of a crash, but this is not designed to work in flight. Aircraft that drop items like weapons in flight require extensive design and testing to make sure that the object will drop away from the aircraft properly.
Why was the fuel dumping system shut down?
It was a very dangerous situation since the fuel leaks were very close to the failed, then burning, engine. And to make the matter worse, fuel dumping system was down due to hydraulic failure. Although the crew managed to shut it down, the engine took considerable amount of time for fire to be extinguished completely.
