Bsieker, thanks for the correction. Does stick shaker on one side only help the pilots to understand what's gone wrong? And is stick shaker only triggered by AoA?

According to the AD bulletin, one of the effects of an AoA sensor failure is 'stick shaker on the affected side only'. So the computers can use 'logic' to determine this.

If each pilot could see his own AoA they could decide which was faulty whether it read FSD, zero or was erratic. Or the computer could flag one as 'out of range'

But the alpha vane was replaced, so it probably wasn't the fault unless both new and old were defective. Maybe the real fault was 'downstream' of the alpha vane?

If only the warning to the pilots had been "AoA disagree - A/P off, STS off" or something precise and useful. And Feel Diff Press should NOT alarm.

Why does a faulty AoA sensor trigger a 'Feel Diff Press'? It does not seem to be an informative message, especially when there is no hydraulic system failure.

And why does an aircraft have three...

What if the pitot/static system is not the root cause?

The engineers investigated UAS three times and would surely have discovered blocked or disconnected sensors. What is the next most likely cause? How many AoA sensors does the A/C have?

not high winds

The article actually says, "The witness said the female pilot apologised for the unusual landing and blamed the wind."

Wind shear? Does anyone know if thermals are a possibility?

only cabin crew injured

I think it was only cabin crew who complained of injuries. Flight crew would have known when the impact would occur (if any).

Thanks to people who pointed out that a 90/270 is a course reversal - that is bleeding obvious to all of us!!! :ugh:

How can a ninety left followed by a two-seventy right not have you flying away from the runway? Or did I miss the half rolls?
