At 38°n 015°e we have the etna volcano . 1242. read the story of british airways flight nine you will find and understand the answer .on 24 june 1982 a 747 flew into a cloud of volcanic ash thrown up by the eruption of mount galunggung south east of jakarta indonesia resulting in the failure of all four engines .at approximately 13 42 utc 20 42 jakarta time engine number four began surging and soon flamed out the flight crew immediately performed the engine shutdown drill quickly cutting off fuel supply and arming the fire extinguishers less than a minute later at 13 43 utc 20 43 jakarta time engine two surged and flamed out within seconds and almost simultaneously engines one and three flamed out prompting the flight engineer to exclaim 'i don't believe it all four engines have failed ' .the flight crew quickly determined that the aircraft was capable of gliding for 23 minutes and covering 91 nautical miles 169 km from its flight level of 37 000 feet .at 13 44 utc 20 44 jakarta time the senior first officer declared an emergency to the local air traffic control authority stating that all four engines had failed however jakarta area control misunderstood the message interpreting the call as meaning that only engine number four had shut down it was only after a nearby garuda indonesia flight relayed the message to air traffic control that it was understood despite the crew 'squawking' the emergency transponder setting of 7700 the aeroplane could not be located by air traffic control on their radar screens .due to the high indonesian mountains on the south coast of the island of java an altitude of at least 11 500 feet was required to cross the coast safely the crew decided that if the aircraft was unable to maintain altitude by the time they reached 12 000 feet they would turn back out to sea and attempt to ditch into the indian ocean the crew began the engine restart drills despite being well above the recommended maximum engine in flight start envelope altitude of 28 000 feet the attempts failed .at 13 500 feet they were approaching the altitude at which they would have to turn over the ocean and attempt a risky ditching although there were guidelines for the procedure no one had ever tried it in a boeing 747 nor has anyone since as they performed the engine restart procedure engine number four started and at 13 56 utc 20 56 jakarta time the captain used its power to reduce the rate of descent shortly thereafter engine three restarted allowing him to climb slowly shortly after that engines one and two successfully restarted as well .the crew subsequently requested and expedited an increase in altitude to 11 500 feet in order to clear the high mountains of indonesia . as flight 9 approached jakarta the crew found it difficult to see anything through the windscreen and had to make the approach almost entirely on instruments despite reports of good visibility .although the runway lights could be made out through a small strip of the windscreen the landing lights on the aircraft seemed to be inoperable after landing the flight crew found it impossible to taxi due to glare from apron floodlights which made the already sandblasted windscreen opaque .aftermath it was found that the b747's problems had been caused by flying through a cloud of volcanic ash from the eruption of mount galunggung because the ash cloud was dry it did not show up on the weather radar which is designed to detect the moisture in clouds the cloud sandblasted the windscreen and landing light covers and clogged the engines as the ash entered the engines it melted in the combustion chambers and adhered to the inside of the power plant as the engine cooled from not running and as the aircraft descended out of the ash cloud the molten ash solidified and enough broke off to allow air to flow smoothly through the engine allowing a successful restart the engines had enough electrical power to restart because one generator and the onboard batteries were still operating exemple 207 Engine flame out and windscreen damage.Engine flame out and windscreen damage.
