Boeing (admittedly under a different CEO) did that quite a few times last year. Share price needs propping up again? :rolleyes:

Using a complex, failure-prone system to cure a simply-fixed and rare problem is generally not a good idea - ask Boeing.


Quite apart from the fact that "an accelerometer in the stick" and its...

Wrong again :) On the A320-330-340 they are full wheels that are mechanically connected to the trim actuator and turn when the stab moves.

The reliability is there, if manufacturers (and customers) will pay for it. That's not the problem.

Not really - just watching with rapt fascination as Boeing racks up nearly a year's worth of unsold aircraft without being visibly nearer a complete solution. Reminds me of the time I witnessed an...

There'll be a Captain on board if only to sign the paperwork and do you think the SLF (who don't know the difference between an NG and a MAX, remember) will complain even if his only other job is to...

I found the next bit particularly interesting. They discuss the need for training for this situation, but don't want to spoil the commonality with the NG. Someone suggests incorporating the...

The non-linearity issue was brought up by FCEng84 way back when the whole thing started in one of the now-closed threads. It is the stick force reversal and instability that are speculations, and...

An X-15 was lost when the attitude target indicator on the artificial horizon was left in yaw mode for ascent rather than in sideslip mode for re-entry (or was that the other way round?) due to high...

Makes one wonder just how deep Boeing's pockets are - and whether any other company without lucrative military sales could do anything like that.
