The dead/live check just prior to shutdown as described by Rolling Circle is the same as was carried out in the Bulldog. Is there any reason why it isn't usually done in the PA28?? What do OATS and the other schools do?? Or is it simply that the average pilot can't cope with BOTH, L, BOTH, R, BOTH, OFF, BOTH....ICO...prop stops, OFF and key out?? I think we did this check at 1000 rpm in the Bulldog rather than the usual 1200 rpm to avoid shocking the engine??
