Reply to comment by BasedOnAir in TIL that flight recorders must be able to withstand an acceleration of 3400 g for 6.5 milliseconds and that this is roughly equivalent to an impact velocity of 270 knots (310 mph; 500 km/h). by IchBinKoloss
to stop over a time period of 6.5msec implies that it stops over a distance. I calculated velocity over the given 1.5ft distance and it was a different impact speed. The real answer is that they reported a max velocity when speed calcs are performed assuming a half sine wave impulse. Meyer explained it to me in a different comment
