The recalculation of distances was done assuming 280 km/h, as last
reported speed, hence app. 78 m/s.
Average speed for most of the important distance can be calculated from marker signal timing registered by the CVR -- the figure is quite accurate, as it's free from "human" delays.
DPRM signal: 10:39:50,20
BPRM signal: 10:40:56
time: 1:05,8
distance: 5 km
speed: 75,99 m/s, 273,56 km/h
(If my maths is OK, of course
