.........god it's hard to believe the amount of stuff written here about what is essentially good airmanship amongst other things. Sure, do engine runups whilst on the move where practicable but use common sense at all times, if it's anyway risky to do so then simply don't !.........sure do runups tail into wind where appropriate but there's no harm doing it (where possible) into wind, back to good airmanship with controls & engine handling, both of which should be respected well before airborne flight:-)
I'm sure all here have seen it all, poor airmanship, poor decision making etc. We are but human but we can make a difference & we can try to do what we believe is correct at every opertunity but never & I mean never at the expense of common sense..........those two words that will always sustain ones life where all else fails.............happy flying & remember the flying isn't over 'till the hangar doors are closed !:[)
