Volcanic Ash
VOLCANIC ASH
On June 24, 1982, the devastating effect of an ash cloud took the crew of British airways jet completely by surprise. Mount “Galangan” on the island of Java has erupted, but no warnings have been issued to pilots. When the 747 flies into the cloud collides with volcanic ash particles inside. The friction creates a bright shimmering glow on the windscreen. Passengers aboard the flight also see a strange glow around the plane`s engines. Smoke begin to see into the cabin around. Volcanic ash has been sucked into the aircraft`s ventilation system. With ash particles cloud in the cabin and the aircraft up. The volcanic cloud deals It`s most deadly blow. The ash has snuffed out one of the jet`s four massive engines.
“The other three just went out almost immediately, that`s when it began to be a serious emergency”
The 747 is suddenly powerless and it`s quickly falling to the sea. Starting the engines has become the crew`s only priority, but volcanic ash is making that tusk impossible.
“The temperature in the combustion chamber where this ash flowing through around 2000 degrees centigrade and so volcanic ash, we know, melts at about 3000, 4000 degrees. The volcanic ash transforms into molten goo within jet engines. The material blocks key air passages and cause that the engines to surge and shut down.”
Then with just 12000 feet separating British Airways flight 009 from the ocean engine №4 rose to life.
“Engine 3 back online. I can`t believe it, engines 1 and 2 both back online”
“ came out of volcanic ash, and the engines were not running remember, so everything cool down, it was enough for this stuff to break off and allow the engines to restart.”
British Airways flight 009 landed safely. No one was injured and important lesson was learned.
