Sigh......
I get tired of hearing all the internet experts pontificating about how you always need a "qualified pilot" at the controls while hand propping, and/or the tail needs to be tied down, with some sort of magic knot......etc.
This is one more of those subjects, like use of the rudder, that we just aren't teaching pilots these days. And, every pilot should learn how to SAFELY hand prop an airplane.
What do you do if you're by yourself? Qualified pilot at the controls? Sure, spend a few nights out there in some bug infested swamp, waiting for that "qualified pilot" to magically arrive to assist.
What do you do out on a concrete ramp, or, as in my hangar, where there simply is NO place to tie your tail off to?
How about we all just learn how to safely hand start an airplane instead? The vast majority of these accidents involve someone who's never propped an airplane before. And, that is NOT a good time to learn how. The result is often ugly.
Further, watch a bunch of pilots start their engines with the starter some time.....R,R,R,R,R,R, etc....Just as the battery is about to die, the poor engine has gotten rid of enough of that flooded start to actually fire.
Ummmm, if you don't know how to start your engine with the starter:
a) One of these days, you're going to HAVE to hand prop the thing, and
b) If you don't know how to start with the starter, your arm is gonna get really sore trying to hand prop.
Here are the "rules":
1) Learn to start your engine, efficiently. If you aren't getting quick starts regularly, get someone to show you how it's done. Most engines start different when hot, compared to when cold....learn both.
2) I prefer to prop from behind. If I slip, I do NOT want to be in front of or under that spinning propeller. This also comes from many hours in seaplanes, the first one of which I owned didn't have an electrical system. If you're propping a seaplane, there are very few of you who can prop from in front.....Propping from behind gives you something to hang onto, to help maintain your balance, and gives you better access to the controls. I've always been stunned at Oshkosh to see the vintage guys showing people how to prop an airplane....from out front.....dumb. Don't do it.
3) If you have a passenger, tell them that under NO circumstances are they to touch the controls. I can almost guarantee that they'll do exactly the wrong thing if they do try to "help".
4) Get someone who knows how to hand prop to show you how it's done. Practice it. Move to a different airplane type? Learn to prop it, before you need to.
5) Tie the tail down if you can, but trust me, there's a lot of places where there simply is no practical place to tie the tail.....so:
6) ALWAYS ensure the throttle is set VERY near idle prior to turning that prop through.
7) Mixture set to idle cutoff, after you've primed the engine. If it tries to run off, it won't get far. As soon as it catches, push the mixture to full rich. Don't try this from out front....running past that spinning meat cleaver can be a career ending experience. Another argument for propping from behind.

Did I mention to get someone to show you how to SAFELY do this? This is another of those things that you should NOT learn from the internet.
Oh, yeah, I propped my airplane twice yesterday.....it doesn't have an electrical system....VERY unsafe, of course.....
MTV
