I hope people are beginning to understand that the presence of software in any system is a liability.

#323I think the auto shutdown of engines in flight, in case it senses reverse thrust, is a great design. The 787 is a replacement for my 767 (currently a pilot on the aircraft) and in 1991 a Lauda Air 767 suffered a failure in one of its thrust reverser and it became activated during cruise. The aircraft was destroyed in flight. The thrust reversers should not activate during flight (a air/ground sensors prevents that) b…
I am very scared of flying (although I still do it, although it's not fun). Any advice/rationalism you can convey? I am a person that became sweaty and anxious reading your post.

Another thing I do is to remember the physics when I'm on a bumpy. Thanks to momentum, planes don't just fall out of the sky, and even bad turbulence is not likely to result in deaths.

Yes, Boeing still puts the RAT - ram-air turbine - electrical backup system on their planes.
Why "still"? Even if the chances of a failure of both engines is almost zero, it has happened that there are losses of fuel. The ram-air turbine allows the pilots to have some instrumentation. That's super useful, for example in this accident: https://en.wikipedia.org/wiki/Air_Transat_Flight_236

#327This is really strange. Not only did they have a dual engine failure, they couldn't restart while stuck on the runway. After 40 minutes, the aircraft had to be towed in. Then maintenance couldn't find a fault. This is an ANA aircraft, which means it's probably maintained well and flown by competent pilots. Looking forward to a good analysis on this. Most large aircraft have a "weight on wheels" switch, activated when…
In that case, the aircraft touched down, reversers were deployed, a runway obstacle (a snowplow) appeared, and the pilots attempted to go around. They got airborne and cleared the obstacle, but as they lifted off, the "squat switches" on the main gear opened. One of the reversers was still deployed, and with the squat switches open, was no longer powered, and could not retract. The aircraft was uncontrollable, and crashed.
In that case, shutting down the reversed engine would likely have been preferable, although if we're doing counter-factuals, telling the snowplow driver about the airplane's revised arrival time is your go-to move, I think.

My advice is to look at the statistics. Commercial flying is much, much safer than any other mode of transport. Do you get scared when you drive to work? Or take a train? Both are more risky. (Driving significantly so.) More specifically... The pilots have extensive training, modern airliners have fail safes everywhere, and the amount of research and engineering spent on aviation safety is mind boggling. See: http://…

I'm always amazed how diverse the people on HN are. Not everyone is an IT professional but we share a passion for technology.
'Passionate' is not the adjective I would use to describe my feelings towards technology.
