This is true in some organizations, but in other places the difference between "technician" and "engineer" literally is an engineering degree. I currently work at such an organization: you can't have the title "engineer" unless you have an

He's still wrong: human error is a factor in the overwhelming majority of aviation mishaps (I don't have stats handy, but it's something in the neighborhood of 85% IIRC). This must be understood in the context that while it is almost always

Nothing you say addresses my broader point that there are currently too many situations in aviation where the complexity of the decisions involved exceeds our current capacity for automation. A billion dollars was spent by the eu in the 80

Occasionally it will disengage, leaving the pilot in full control. IIRC, when in full-auto it will automatically wave off (add power and climb out to go around and try again) when it disengages unless the pilot actively takes over; so it w

Automated systems as they currently exist have fixed responses to fixed inputs. If an automatic system encounters a set of inputs it wasn't programmed for, it has no capacity to determine a best course of action for those inputs. Dependin
