The Seventh Arc

Information and analysis of satellite data and drift modelling identified an area set out in the map and labelled as the 7^th arc. At the time MH370 reached this arc, the aircraft is considered to have exhausted its fuel and to have been descending. As a result, it was determined that the aircraft was unlikely to be more than 27.5 NM (51 km) to the west or 25 NM (46 km) to the east of the arc.

The ATSB encourages constructive feedback.

On 8 March 2014, the Boeing 777-200ER aircraft registered as Malaysia Airlines 9M-MRO and operating as flight MH370 (MH370) disappeared from air traffic control radar after taking off from Kuala Lumpur, Malaysia on a scheduled passenger service to Beijing, China with 227 passengers and 12 crew on board.

After analysis of satellite data it was discovered that MH370 continued to fly for over six hours after contact was lost. All the available data indicates the aircraft entered the sea close to a long but narrow arc of the southern Indian Ocean.

Acc Rep

Accredited representative. In accordance with Annex 13, the ATSB may assist other overseas agencies in the investigation of accidents and serious incidents that do not involve Australian registered aircraft. In these cases an ATSB investigator would be appointed to the investigation as an accredited representative. On 1 April 2014 the ATSB appointed an accredited representative to the MH370 investigation, at the request of the Malaysian Government.

The following factsheets provide useful background information on the operational search for MH370.

Safety concern

The ATSB continues to investigate accidents—many fatal—that involve pilots flying with reduced visual references.
