|    Cockpit voice recorder of doomed Lion Ai    |

      XPost: alt.gossip.celebrities, alt.politics.democrats.d, sac.general       XPost: alt.rush-limbaugh       From: burr-head.airlines@cnn.com              It is the first time the voice recorder contents from the Lion       Air flight have been made public. The three sources discussed       them on condition of anonymity.              Just two minutes into the flight, the first officer reported a       “flight control problem” to air traffic control and said the       pilots intended to maintain an altitude of 5,000 feet, the       November report said.              The first officer did not specify the problem, but one source       said airspeed was mentioned on the cockpit voice recording, and       a second source said an indicator showed a problem on the       captain’s display but not the first officer’s.              The pilots of a doomed Lion Air Boeing 737 Max scoured a       handbook as they struggled to understand why the jet was       lurching downwards, but ran out of time before it hit the water,       three people with knowledge of the cockpit voice recorder       contents said.              The investigation into the crash, which killed all 189 people on       board in October, has taken on new relevance as the U.S. Federal       Aviation Administration (FAA) and other regulators grounded the       model last week after a second deadly accident in Ethiopia.              Investigators examining the Indonesian crash are considering how       a computer ordered the plane to dive in response to data from a       faulty sensor and whether the pilots had enough training to       respond appropriately to the emergency, among other factors.              It is the first time the voice recorder contents from the Lion       Air flight have been made public. The three sources discussed       them on condition of anonymity.              Reuters did not have access to the recording or transcript.              A Lion Air spokesman said all data and information had been       given to investigators and declined to comment further.              The captain was at the controls of Lion Air flight JT610 when       the nearly new jet took off from Jakarta, and the first officer       was handling the radio, according to a preliminary report issued       in November.              Just two minutes into the flight, the first officer reported a       “flight control problem” to air traffic control and said the       pilots intended to maintain an altitude of 5,000 feet, the       November report said.              The first officer did not specify the problem, but one source       said airspeed was mentioned on the cockpit voice recording, and       a second source said an indicator showed a problem on the       captain’s display but not the first officer’s.              The captain asked the first officer to check the quick reference       handbook, which contains checklists for abnormal events, the       first source said.              For the next nine minutes, the jet warned pilots it was in a       stall and pushed the nose down in response, the report showed. A       stall is when the airflow over a plane’s wings is too weak to       generate lift and keep it flying.              The captain fought to climb, but the computer, still incorrectly       sensing a stall, continued to push the nose down using the       plane’s trim system. Normally, trim adjusts an aircraft’s       control surfaces to ensure it flies straight and level.              “They didn’t seem to know the trim was moving down,” the third       source said. “They thought only about airspeed and altitude.       That was the only thing they talked about.”              Boeing declined to comment on Wednesday because the       investigation was ongoing.              The manufacturer has said there is a documented procedure to       handle the situation. A different crew on the same plane the       evening before encountered the same problem but solved it after       running through three checklists, according to the November       report.              But they did not pass on all of the information about the       problems they encountered to the next crew, the report said.              The pilots of JT610 remained calm for most of the flight, the       three sources said. Near the end, the captain asked the first       officer to fly while he checked the manual for a solution.              About one minute before the plane disappeared from radar, the       captain asked air traffic control to clear other traffic below       3,000 feet and requested an altitude of “five thou”, or 5,000       feet, which was approved, the preliminary report said.              As the 31-year-old captain tried in vain to find the right       procedure in the handbook, the 41-year-old first officer was       unable to control the plane, two of the sources said.              The flight data recorder shows the final control column inputs       from the first officer were weaker than the ones made earlier by       the captain.              “It is like a test where there are 100 questions and when the       time is up you have only answered 75,” the third source said.              [continued in next message]              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
