We teach that full flap should always be used in the PA28-140 and PA28-161, and carb heat checked OFF on final.
Do NOT let any idiot show off with a '120 KIAS over the hedge' landing in a PA28-161, that's a sure fire way to collapse the noseleg and is some 57 knots in excess of the correct 63 KIAS approach speed. Whoever 'Andy' is should have his ar$e kicked hard for such stupidity!
