airtren, henra,
the question if the BEA speeds are CAS or TAS are not realy clear for me, up to now I tought CAS
I was not on the search for negligable faktors, just trying to re-calculate the energie for my self (fighting with non metric units as before....)
I think they flow with mach 0.82 at F350 and planed to climb to F375 (flightplan) and in the same moment wanted to reduce the speed to mach 0.80 (turbulence) so they start the climb without more trust....... and then start the UAS event...........
if v2=0 then
v1^2 - v2^2 is equal to (v1-v2)^2 ..... so "dont hang up" uses the second formula just for argumenting how high maximal you can climb before you stand still (V2=0) with given v1....
