Touched a nerve Ghostly?
If you care to read correctly, it was a AB guy (jshg) who brought up the AT theory. Sure enough this hardy must not necessarily be of a AT origin, but I stepped in to reconfirm my ever sceptical comments on the "fixed" design.
To compare with the LHR/777 incident just shows some incompetence, as such a thing (demand with no response) can happen in any design, no connection to fixed or moving levers.
Once again: Give me ONE situation where the fixed solution is superiour, or proves to be a advantage over the moving one, and we can start debating. I have not found one. On the other hand there are some examples that would have been picked up or corrected easier with the moving design. The argument that you can fly manual thrust, and many many more AB pilots do that compared to the other bunch, only proves that theres a issue.
Happy flying on any design, each one has it's flaws. The pros just recognize them and deal with them. The fans who deny them unconditionally scare me, just as the manufacturers who never admit and correct to a better design.
