The timeline of Malaysia Airlines Flight 370 lists events associated with the disappearance of Malaysia Airlines Flight 370—a scheduled, commercial flight operated by Malaysia Airlines from Kuala Lumpur International Airport to Beijing Capital International Airport on 8 March 2014 with 239 passengers and crew. Air traffic control lost contact with Flight 370 less than an hour into the flight, after which it was tracked by military radar crossing the Malay Peninsula and was last located over the Andaman Sea. Analysis of automated communications between the aircraft and a satellite communications network has determined that the aircraft flew into the southern Indian Ocean, before communication ended shortly after 08:19 (UTC+8:00). The disappearance initiated a multi-national search effort that became the most expensive search in aviation history. In the weeks after Flight 370's disappearance, the search focused on waters in Southeast Asia and an investigation into the disappearance was opened. After a week of searching, Malaysia announced that analysis of communications between the aircraft and a satellite communications network had found that Flight 370 continued to fly for several hours after it lost contact with air traffic control. Its last communication on the network was made along one of two arcs stretching north-west into Central Asia and southwest into the southern Indian Ocean. The northern arc was discounted and the focus of the search shifted to a remote area of the southern Indian Ocean. On 18 March, a surface search in the southern Indian Ocean, led by Australia, began; it continued until 28 April and searched of ocean.〔 On 24 March 2014, Malaysia's Prime Minister announced that Flight 370 ended in the southern Indian Ocean with no survivors. In early April, an effort to find the signals emitted from underwater locator beacons (ULBs) attached to the aircraft's flight recorders, which have a 3040 day battery life, was made. Some possible ULB detections were made and a seafloor sonar survey in the vicinity of the detections to scan the seafloor was initiated. The seafloor sonar survey ended on 28 May and scanned of seafloor.〔 Neither the surface search nor the seafloor sonar survey found any objects related to Flight 370. In May 2014, planning for the next phase of the search was initiated. A bathymetric survey was carried out to measure the seafloor topography in the areas where the next phase was conducted; the survey charted of seafloor topography and continued until December that year.〔 an underwater search begun in October 2014 is ongoing. On 29 July 2015, a flaperon from Flight 370 was discovered on a beach in Réunion, approximately west of the underwater search area; this location is consistent with drift from the underwater search area over the intervening 16 months. ==Disappearance (8 March 2014)== Flight 370 took off from Kuala Lumpur International Airport at 00:42 local time (MYT; UTC+08:00) en route to Beijing Capital International Airport, where it is expected to arrive at 6:30 local time (CST; UTC+08:00). At 1:19, while Flight 370 is over the South China Sea between Malaysia and Vietnam, Malaysian air traffic control (ATC) instructs Flight 370 to contact the next ATC in Vietnam. The final voice contact from Flight 370 is made when its captain replies, "Good night. Malaysian Three Seven Zero". Two minutes later, the aircraft's transponder stops functioning, causing it to disappear from ATC's secondary radar. Malaysian military radar continues to track the aircraft as it turns left, crosses the Malay Peninsula near the Malaysia–Thailand border, and travels over the Andaman Sea. At 2:22, the aircraft disappears from Malaysian military radar, north-west of Penang. At 2:25, the aircraft's satellite datalink, which was lost sometime between 01:07 and 02:03, is re-established. Thereafter, the aircraft's satellite data unit (SDU) replies to five hourly, automated status requests between 03:41 and 08:10, and two unanswered ground-to-aircraft telephone calls. At 08:19, the SDU sends a "log-on request" message to establish a satellite datalink, followed by the final transmission from Flight 370 eight seconds later. Investigators believe the 08:19 messages were made between the time of fuel exhaustion and the time the aircraft entered the ocean. After four hours of communication between several ATC centres, the Kuala Lumpur Aeronautical Rescue Coordination Centre is activated at 6:32. Malaysia Airlines releases a press statement at 07:24, stating that contact with Flight 370 has been lost. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Timeline of Malaysia Airlines Flight 370」の詳細全文を読む スポンサード リンク
