what data are the 'heights' plotted in this 'simulation' based on?

If i didnt miss anything (e.g. Amielin finding access to the FDR recordings or other radar data), the heights plotted in the chart are simply deduced from height call outs found in the CVR script and, later on, from the 'struck heights' of the respective trees.

And thus it is his interpretation, that the first call outs refer to barometric altimeter readings (down to the 1str 100m call out), and refer to RA readings beginning with the second 100m callout.

Although this scenario might seem likely, it is based on no substantial data.

So taking Amielin's plot to deduce that the first call pout were on barometric height and the later ones on RA height seems to be a bit like 'thinking in circles'....they are there because Amelin has put them exactly at these points....since they are the basis of the whole 'simulation'.
