Contained within the OnPoint Program is the real time diagnostic program. There are two levels, Standard or Comprehensive, the Comprehensive can be custom designed to whatever the aircarrier would like. For what we would be interested in, the Standard program will show fault alerts, exceedance alerts and would notify the aircarrier of "critical" detected anomalies. The Comprehensive program would do the same as the Standard program but also would diagnose (diagnosis done by GE) the fault alerts and would detect all anomalies. So the data transmitted by each engine to GE & AF would depend on which program AF selected.
The data sent in either case would show all the key engine operating data, N1 and N2 speeds, oil quantity & temperatures, EGT readings, fuel consumption, air pressure entering the combustor, high vibrations, etc. The detected critical anomalies would include high EGT, flame out/compressor stall conditions, fire, commanded engine thrust levels outside normal operational conditions, etc.
I don't know what AF signed up for, but the data is very comprehensive and dates to the very first flight of the engine sending the data.
Sorry for the delay, but we have had bad weather here today...
