The pressing of the standard pressure selector at the electronic
pressure altimeter on final (at about 350 m) was absolutely illogical
and was probably caused by mixing with the QFE button located near the
MFD-640 of the TAWS that had to be pressed at the transition
level. The pressure selector at the pressure altimeter could only be
reached by the PIC or the navigator who was seated between the
pilots. It is improbable that the PIC who was engaged with the flight
control at that moment could do this. Besides, the PIC out of all the
crew members had the longest experience on this aircraft type. As for
the navigator, he had insignificant experience on Tu-154 (total 59
hours and unsupervised 26 hours, with a break of 2.5 months) and most
probably was the one who could do this action.
