Aviation Industry Hardware/Software

Fly by wire, automated control systems , and side stick controllers have put pilots in a precarious position during ' protected mode ' to 'direct law' transitions.

How so?

I would argue that in practice their introduction has made air travel more safe over the years.

I am not disputing that these systems have not directly resulted in a few plane crashes through operator error or software failure (because they have, and are well documented), but given the amount of air travel in this modern day and age traveling by air is even safer than it was before these systems were implemented.

Automated systems were put in place to smooth out the ride and fuel efficiency, and it does that very well, but the trade off has been too much reliance on the 'sensors'. When they malfunction, it takes time for the pilots to figure it out and gain control from the 'software'. In the airbus, the side stick controllers are not 'mirrored' or connected, thus even more time to take back control. I agree that air travel is much safer as time goes by, but mainly because of the incredible skill of the pilots and their training. There have been more and more situations where the pilots have had to take control from an automated system because of sensor failure. Software improvements are an evolution, and will help pilots be able to 'troubleshoot' quicker. The planes themselves are some of the most sophisticated machines ever built.

Like anything, it's a game of percentages...Does your car have electric windows? Is there a chance that you could drive the car into a body of water, have the windows short out and be inoperable? Yes, but what are the odds?

Know your emergency procedures...drill baby drill...

The airbus link you presented talks about 'sidestick deflection, but there are 2 sidesticks who don't know each other, which adds time. Another thing that adds time is the fact that some pilots are left handed and sit in the right seat and vice versa. Either way, time is of the essence in these transition periods. (Airbus pilots now can take 40 minute power naps in their seats, to prepare for the next check list)
