'I cringe when I see people handling propellers casually, putting arms and necks through the discs on walkarounds, pull aircraft by the blades, curl fingers around the trailing edge when hand-swinging or sucking in, stand or walk too close to props and tail rotors. I can't help but form opinions about professionalism based on what I see'.
So true. It astonishes me the amount of pilots who have an apparent indifference to the dangers posed. I have spent a great deal of time flying types that require hand swing/suck in, and the time spent at or near props is when I give it my utmost attention. I have only had one fire on me, a Chipmunk, engine warm, there were two people standing close, thank God I asked them to move, I turned the prop, and it fired.
I also would only allow another pilot to do a hot swap, even then, it is fully briefed, even pointing in the direction they have to go. Not a place for complacancy.
