This engine database thing is interesting. I wonder if it’s a satellite based system, which is non-directional. Also, if the databases have info, they may indicate engine operating parameters (RPM, fuel consumption), which my indicate some minimal information about flight conditions.
Here’s some info:
My SIL works in engineering for RR but he hasn’t responded today to my request for a briefing...
Reportedly, it uploads engine performance data over a satellite link every thirty minutes, probably including air speed and altitude, but, alas, not lat/lon nor heading.
