One feature of both crashes was that none of the pilots seemed to note the trim position and how far it was from the normal location nor that the reading was changing. The first, safe flight, appears to have been regulated by the PIC feeling the excess load to hold the nose up rather than the reading of the indicator.
Perhaps this is a problem that the difficulty of using a dial to produce a value rather than the digital display of a number has moved from children being unable to read a clock with hands into the cockpit. Pilots know what V1 is and what V2 is and what flap settings to use, but somehow the most powerful control, trim, is not given the same concern? It must happen as it controls the relation between weight and flight speed?
