IIRC, Airbus or Boeing have yet to have an aircraft have to land using direct law. The redundancy is built in and has proven to be rather effective.What you said is true, and does not invalidate my statement.
Like stated earlier, this has been in progression since the early 80's, and everything (large transport) is using it. Even the modern business jets are very heavily software controlled.
There are compromises in everything. Make everything fly by wire, and you can save weight by making components thinner. They didn’t help AA Flight 587, an Airbus A300 that has the vertical stabilizer tear off because of excess rudder forces.
I have been involved in some Safety Stand Downs in the CAF. One lesson that keeps popping up is a four-part video of NASA astronaut Mike Mullane talking about “Normalization of Deviance.” Put simply, that’s normalizing actions because you haven’t had a problem in the past. Example: not wearing your seat belt because you haven’t been in an accident. In Mike’s case, he was demonstrating that the Challenger and Columbia crashes weren’t accidents; they were predicable events.
This is part 1 and well worth the 16 minutes. The other 3 parts can be found on YouTube and are great.
