The way I understand it, the way the logic works is like this:
If (engines running) then {
Every half hour {
Get (time, direction, speed, altitude);
If (engine event) then Get (engine status);
Get (other information);
Ping (time, direction, speed, altitude, engine status, other information) to recipients;
}
}
But, because the engine status and other information reports have been switched off, what was actually happening was:
If (engines running) then {
Every half hour {
Get (time, direction, speed, altitude);
Ping (time, direction, speed, altitude) to recipients;
}
}
On reception by Rolls Royce, this ping is automatically detected as null information and is therefore filtered out, probably with no record.
The ping with time, direction, speed, altitude comes from a source other than Rolls Royce.
What we know as a consequence of the US analysis is the location at the last ping, its then current time, direction, speed, altitude and when the engines were switched off.
There appears to be a gap in time between the last way-station and the reported engine off time. This is because the way-station is in the middle of the ocean. Hence, this does not tell us much.
Question: if the routing had been maintained after the last way-station passed, what would be the identity of the next way-station and when would it have been passed?
