Question.
The same aircraft, with the same crew, and the same TR inop, landed at Porto Alegre only a few hours earlier.
The recording of that landing should still be in the FDR. Have there been any suggestions yet to compare the two landings, and see what procedure was used at Porto Alegre?
The CVR probably won't be of any use for that, because it would have been on a 30-minutes or 2-hours endless loop (depending on type), but the FDR would be on a 25-hours loop or suchlike, so the data should be there.
