barit1,
If you're referring to the sampling rate for the vertical acceleration on the FDR, I concur.
However, if you take the last few data points for vertical speed, combine that with the landing gear geometry, and apply some basic physics, I would think you'd get a reasonable approximation for max. G. Structural analysis would then provide a cross check.
I believe that was what he was refering
You do the input modeling first, as you have said, and then you tweak a couple of input varriables until you match the damage. In the end, once the model has closed on the damage, without violating known DFDR data input points, then you can interpolate missing data like vertical acceleration.
