Hi HN39,
Sorry to catch you "on the hoof"! When you have time to have a closer look, our one-second discrepancy in timings is identified in your answer.
Quote from your response (my emphasis):
"At 12:45:34 airspeed is122 kIAS and Alpha is 13 degrees is recorded at 329.0s"
My interpretation is that 329.0s = 12:45:33 (see explanation offered in my previous post). But I have little experience in DFDR readings.
Quote:
"Five seconds later at 12:45:39 t=0 so that must be at 329.0s + 5 = 334.0s"
According to my interpretation, that should read "six seconds later". As you can see in my previous post, I have the AoA datum of +13 at t -6.
PS
I now understand what you meant about all the parameters in a one-second time frame not necessarily being recorded at the same instant, but possibly sequentially during the whole second. Do you or anyone else have any news on that?
