For IFR or flight at night TAWS has its benefits, I have this equipment in the jets I fly. But I think it is a waste of money for day VFR flight. I used to fly jumpers in a Kodak which has TAWS and EGPWS as part of the G1000 system. I never could figure out how to shut the ground prox off, so since the drop zone and runway was a private strip it was not in database. Had to listen to “terrain pull up terrain” on every landing after dropping off jumpers at altitude, along with “sink rate” on descent below 2500ft agl. I wonder how this works out when the Kodak is used as designed for “bush” operations. Got to drive those pilots nuts if they cannot turn the system off. Two of my company’s jets have a system that verbally announces the planes’ location on field in relation to runway. It has an annoying habit of announcing “short of runway__” at the same time the tower issuing a clearance or my FO making a required call out. Most of the other pilots and myself disable that system because of that interference. It is another system the NTSB wants the FAA to mandate.
You can continue to come up with and install more “safety” or warning systems to the point of everything “crying wolf”. At that point pilots will just ignore that warning or pull circuit breakers to shut that system off. Whether that is right or not it is human nature to figure out a way around such systems. All the warning systems in the world will not help at this point.
