I am thinking about the 737-MAX crashes. There is a similar question at Is it common for automated control systems to use non-redundant sensors? There was an article in yesterday's Seattle Times In key step for potential late-November ungrounding of Boeing’s 737 MAX, FAA details minimum pilot training which references Why Boeing’s emergency directions may have failed to save 737 MAX.
My thinking is that if the pilots are applying a force to a control which is near the limit of the strength of a human being, then the control system ought to recognize that the pilot is fighting with it. If the control system recognizes that the pilot is fighting with it, then it ought to assume that the pilot knows what he or she is doing, and let the pilot do what he or she wants to do. There might be an indication along the lines of "Are you sure you know what you are doing?".
I order to recognize that the pilot with fighting with the system, I propose adding a strain gauge to the controls. Normally, one should be able to fly the airplane with one hand. If a pilot is using two hands to fly and is using large forces to do so, the strain gauge will detect that (technically, the pilot is stressing the control by applying a force, and the strain gauge is measuring the deformation of the parts the pilot is forcing), and that will tell the automatic system to "let go" and do what the pilot wants to do.
Does this sound like a good idea? I am neither a pilot nor an aeronautical engineer. However, I once worked as a computer programmer in a test lab and I wrote software to test strain guages.
