However, the CVR did not record “DUAL INPUT” voice message as it was suppressed by “STALL” voice warning.
Surely that should not be necessary? All the captain has to do is declare he has control of the aircraft. It's fairly obvious that he knew what to do and the FO didn't.
Could there be some unusual dynamic here, e.g. the Indonesian captain somehow feels inferior to the European FO? Surely not.
