Absolutely, SC, hence my #1169. I must be remembered, however, that once all the designers and engineers are done, and something is wrong with what they have done, that we have, for the foreseeable future at least, one human there who SHOULD be able to do some old fashioned flying (that is without software) and save the a/c and lives.
Yes, if something prevents them doing that it must be investigated and designed/engineered out - see para a). I have yet to see any evidence that such existed, but the F/O's sidestick trace would be of interest to me - or have I missed it on the traces? On an AB, does the 'Captain's sidestick position' always represent that or the master stick position?
EDIT: Picking up on Scotty: I think from what I have learned the sidestick is a rate demand rather than a position demand? Hence if the nose-up stab effort (at 263kts) was producing at least the designed max pitch rate, the elevators would be in opposition? Whether the airframe would have withstood max elevator as well I do not know. The nose was pitching up fairly rapidly after all at impact
Once again we appear to have the excessive stab trim/pitch couple causing the major upset. Is it time this was eliminated in the software? Perhaps some over-rideable limit on trimming range? As we know this is certainly an area where crew training needs to change.
