Boguing,
Second that thought
.
This seems to me like it would be a perfectly workable solution.
By locating load cell/strain gauge arrangements near or at the MLGs and NG, the weight and CG location could be measured directly, thus eliminating guesswork.
It looks like STAN did just that.
The whole setup could be periodically checked/calibrated against ground pads.
The challenge would then be to come-up with a setup that would remain accurate and calibrated in spite of the higher loads encountered during landing and wide temperature variations.
Could someone more knowledgeable on the subject shed some light
?
