Ablie gave some good links for some gouge. Here is another one. There is a lot of info out there. This test was originally developed to make sure people with neurological issues could continue to fly. It has morphed into a discriminator. I'm with some other posters...this shouldn't be a pass/fail test. It should be one factor weighed against the others. It isn't like we're hand flying approaches to 50' or flying in the Nam!
