Notes
Take-Off and Departure seem to be different, but obviously related, events:-
- ACARS sent the OOOI B777 OFF Report at 16:41:43 UTC Friday, 7 March 2014 or 00:41:43 MYT Saturday, 8 March 2014.
- An OOOI Off-the-ground event is triggered by take-off with the nose gear squat switch extended.
ACARS OOOI messages were sent over a satellite communications link via an Inmarsat IOR satellite. The B777 OFF Report was sent to multiple recipients, including Malaysia Airlines. - A position report was also generated at 00:41:43 MYT. This was the first of six position reports generated at five-minute intervals before being sent as a Position Report by ACARS at 01:07:29 MYT.
- Malaysia Airlines stated the departure time as 12.41am by which they meant 00:41 MYT Saturday, 8 March 2014, or 16:41 UTC Friday, 7 March 2014.
The time quoted could have been rounded down from the B777 OFF Report at 00:41:43 MYT.
- An OOOI Off-the-ground event is triggered by take-off with the nose gear squat switch extended.
- The Departure Message for MH370 has the official departure time at 1642 UTC 14-03-07 meaning Friday, 7 March 2014. That is 00:42 MYT Saturday, 8 March 2014.
As the Departure Message was not sent by ACARS, it is likely to be the same as the 'normal beginning-of-flight message' sent by the IFE SMS e-mail application after take-off, at 1642:04 UTC (00:42:04 MYT Saturday, 8 March 2014). Source: Safety Investigation Report MH370/01/2018 2.5.1 Summary of Key Observations of the SATCOM Ground Station Logs
After take-off, the In-Flight Entertainment System (IFE) Short Messaging System (SMS) e-mail application sent a normal beginning of flight message at 1642 (containing the correct Airborne Earth Station (AES ID), Flight ID “MAS370”, origin airport “WMKK”, and destination airport “ZBAA”), indicating that the IFE was receiving the valid Flight ID, origin airport and destination airport from Airplane Integrated Management System (AIMS) and the ICAO (AES) ID from the Satellite Data Unit (SDU) at this time.
