Regarding my earlier post about thrust settings:
75 degrees thrust lever angle is TO/GA at least according to:

75 degrees was set and constant according to the FDR readout in the preliminary report.
Also there is a reserve power setting that is automatically activated for wind shear, engine failure or by placing the thrust levers at 85 degrees.
