Following the checklist with the cacophony of noise alerts and aural tones, the luckless souls were supposed to ignore all the noise, and NOT fly manually.
If what is contained in the article is correct, this is beyond a service bulletin and requires an immediate cessation of operations and grounding until the root source of the fault is identified, isolated and rectified.
Give the often repeated mantra of 'commercial viability' the regulatory authorities would appear (again if this article is correct) to be quite happy to throw the luckless pilots flying this junk under the oncoming bus.
The QF A330 that took the plunge, twice, didn't result in grounding the fleet, despite the authorities NEVER working out what happened. Airbus came up with a procedure where crews push-button-disabled a particular system.
SLF question: so "fly the damn airplane", oft-repeated above, would in this case be the worst possible advice (and was most likely what the luckless crew were trying to do)?
If you're comfortable handflying and the aeroplane starts doing something in pitch you don't like with, say, full back stick, you trim against it. Or you grab the trim wheel and stop it. Or you engage the AP! My point is, you have to be happy with hand-flying to be able to have spare brain space to try something.
So,
is the STS the culprit when the speeds/AoA go haywire?
