Magneto Checks on Shutdown
I was taught and have always taught that prior to shutdown students should do a quick Magneto dead-cut check. ie quickly switching mag's to off and back to both determining that the mag's are not live in the off position. This is a safety check to reduce the possibility of a prop kicking back when handled. However I've noticed a number of students checking the "L" and "R" positions prior to shutdown and not the deadcut check. Is there any useful reason for doing this, apart from checking both mag's are working, which should be checked prior to takeoff on the next flight anyway. Any comments?
