The DMT is a Rorshach type test is it not? That leaves a lot to the
interpretor. I have trouble with that myself. I'm wondering if there is a
written instrument for denial out there that might be used.
I too believe that pilots should be self-regulators. My research group has
developed a training program called "Personal Minimums". We have a
powerPoint version, and a video version called, "Making Your Own Rules", and
we'll soon have a CBT version. It is aimed at general aviation but has
application to aircarrier pilots as well.
