The majority of pilots these days survive because the aircraft don’t fail 99.999% of the time and they just follow the SOPs designed for the weakest pilot in the weakest operation with the autopilot doing the flying for 99.999% of the time.
This isn’t the fault of the pilots; it’s the fault of training departments filling the training syllabus with inane rubbish like watching an RNAV approach with the AP on for twenty minutes or ten minute briefings in a full motion simulator doing laps of the hold with again the AP on.
Remember the Children of the Magenta? Well they grew up and became today’s training department managers and chief pilots. It ain’t the fault of the line pilots for the last 10-15 years. They only do what they are told/trained to do.
Attitude is a reflection of leadership and leadership in training is non-existent in the majority of airlines these days.
With regard to the specifics of this thread; the problem can be solved by doing two easy things 1) turn off the affected system 2) fly the aircraft manually.
1) Most crew wouldn’t know what hit them if this kind of failure occurred - see all above examples 2) most pilots can’t fly the aircraft manually.
