500e - I actually noticed after I posted that there is a footnote in the report that basically says that there is an upgraded HUMS groundstation available that automatically flags up any problems but this version wasn't being used.
It does seem like a rather large hole in the Swiss cheese to not have had that from the beginning. I've seen some of the kind of data HUMS spits out and it's not (as far as a stupid pilot like me is concerned at least) always easy to interpret.
Huey - no, HUMS parameters are downloaded to a data card which is then removed from the A/C at the end of the flight and downloaded again onto an engineering groundstation. Live streaming would be impractical and hugely expensive right now I'd imagine.
