...up thread we had a great review of STS which indicated that it had many of its “own” inputs, including pitots on the stabilizer leading edge, hydraulic pressure A v B comparisons, also required AP OFF, low weight, aft C/G, 10secs post liftoff, 5 secs after release of trim switches....virtually a separate system.
Does this Boeing bulletin show that the AoA and ADR are in fact also inputs to the STS?
Apologies if I (mere SLF) am mis-interpreting....but it sounds as if once the AP is disengaged, the STS was then available to act on the stabilizer. And the STS was taking ADR info sent from (apparently faulty ) AoA data. Thus pushing nose-down. And perhaps loading the yoke make it harder to pull up.
From what I can find on prior posts (and online Boeing tech info) it did not seem that STS took AoA data as an input. But does it?
All info appreciated! Thanks for a great forum.
