Polish accreditee to MAK said in interview to Polish TV today, that for now they simply don't know whether pushing GO AROUND ,without having programmed approach in advanced (literally he said about "ILS approaches"), will leave a mark on FDR.
And to determine this, they are conducting these flights with TU154M-102.
As for full throttle:
In about middle of this thread someone posted page from TU154 instruction describing GO AROUND engine inertia with regard to descend velocity. It stated (if I remember correctly) 50m descend at 6m/s. And it's consistent with available data. FO said "Odchodzimy" at 80m, they started gaining altitude at 10-20m.
Wouldn't that be consistent with data from instruction?
PS. Unfortunetely in Poland nobody mentions publishing FDR, discussion mostly revolves around publishing new versions of CVR transcripts. Apparently we were able to recover almost all words from it, as opposed to Russian work. And in the same interview Mr Klich admitted, that they recognized PIC voice giving "go around" command, which FO confirmed.
