...isn't a mag check standard operating procedure for ANY mags in the case of rough running engine? I think the only issue is if you have time to do it, but it is not peculiar to EMAG/PMAG. I had to do this with a LASAR failure and it was unequivocal, but I had time and a conveniently located runway that I had just departed from

BTW, that event was what lead me to get dual PMags
