I will include that in a full run. Effectively that is what I did in section 7.9 of the paper but didn't include much detail. It will need a different average speed from 18:29UT to 19:41UT, but that may be consistent with potential scenarios for the flight. I was trying to keep the model simple, as I said.
I wasn't overwhelmed by the ATSB fact sheet when it was released. The scale is small, but the ping-ring map seems to show the same wrong data as the Malaysian presentations, and there is speculation about possible navigation waypoints on the route. It wasn't clear what level in the investigation it had come from.
