Hi bumper, I am the Schweizer driver at the airport. With great interest I read the many sophisticated suggestions, but I fear they miss the most basic improvement needed. Your instrument gets right up in the pilots face with constant criticism. I get enough of that at home.

This is not all tongue in cheek. You may have noticed I have no instruments for just this reason. However as you are the most innovative builder perhaps you could come up with something with positive reinforcement. I am thinking pneumatic. ;-)
