I second what FFF says: fly by attitude. "LEARN the attitudes" said my instructor 97 times during every flight and every de-briefing. My rubbish circuit flying got so much better whenever he covered up the ASI. I am still guilty sometimes of looking at the ASI too much, but much less than I used to be. I don't even know how to spell PAPI, and have never knowingly looked at one. Most GA fields don't have them and, as FFF says, they aren't intended for us in our puddle jumpers.
