I had an instructor who "made me" fly circuits with everything covered up, would not even let me see the RPM, nothing but a big map over the panel.
"Just fly attitude" he said.
One night just as I became visual on an ILS, I switched on the landing light and all the panel lights went out.
Nothing to look at but the R/W lights and too close to the ground to think about the torch,
"just fly attitude"
