Crew Force Measurements for FDR
 

OK to get a real flight test question on the forum.. .. .Has anyone had any reasonable results (you decide the limits) for the FAA's wonderful new FDR parameters, Crew Force Measurements?. .. .Our experience is that the measurements seem to be tracking what's going on in the flight control systems but it isn't exactly the linear parameter you'd expect.

For those of us who don't have the dubious pleasure of dealing with FAA regs, could you elaborate a bit. What forces are you expected to measure, and what is it apparently non-linear in relation to?. .. .G
