Perhaps a bit more emphasis should be place on looking out the window and judging speed and attitude correctly. When I first learnt to fly in microlights I did a good number of circuits with the already sparse instruments covered up, flying totally by the feel of the aircraft and what I saw out the window.
Something that stood me well yesterday when on the climb out an insect flew down my pitout tube and blocked it!! The airspeed dropped off to zero indicated. I flew the 10 miles home and land by the feel of the aircraft judging speed and attitude. A non eventful landing followed by the removal of the offending insect body.
