Yep...
Boeing had the STANS system installed on cargo 707's many years ago, and in my experience, it worked pretty good.
Now, let us suppose that one flies a particular type a lot, and has come to notice that, with normal pax/baggage/freight loading, the 'normal' stab trim from the computer load sheet is (for the sake of discussion), 4.4 units, nose up.
Then, one fine day, the pilot notices that, with the more or less normal pax/baggage/freight load, the stab trim is proudly announced on the load sheet as.....3.1 units, nose up.
One wonders...do most pilots just blindly set this amount of stab trim for takeoff, without looking slightly deeper into the reason why the stab setting stated on the trim sheet is ah...just slightly different than normal?
And further, when one has been given the estimated payload at dispatch, and determined the fuel required for the planned flight, then finding the load sheet rather far from the estimated TOW (originally), do most here just insert the TOW into the FMC, without questioning the reason for the discrepancy?
