Megan, I was thinking that if the history recorders were similar to GE;s, collective position, along with a number of other useful parameters would be there. Of course if there were usable FDR and CVR data the FADEC data wouldn’t be needed. But the FADECs have their own dedicated power source ( for one-they typically have ship power as well. ), so if the ships power did in fact completely fail, the FADEC data will still be there.
