Robin Olds did that in his 38. Droped his tank and forgot to switch to internal. Shot down a Hun while his engines were still off. He restarted his engines in flight.  :old:
I heard about that.

I did it once in my grandmother's Ford Granada when I was 16 and blew the muffler off it. :eek:

This is not the same thing, removing  spark  and returning it with out shutting off fuel from a plane is not a wise move in a plane. Fuel builds and then is ignited in the exhaust manifold.

Yeah, I was pretty sure there wasn't a muffler on the R-2800 Double Wasp. Probably a better fireball on the P&W too.

I blew two mufflers out on a 71 Camaro a long time ago.  :D

CIn reciprocating engines, it's just a matter of ensuring the fuel pump is on and the mixture is open. Restart is simply a matter of turning the key at that point and the power comes back almost instantaneously.



If you used the mag switch (what I assume you're referring to as the key) to shut the engine off you're probably going to have a very rude awakening when you turn the ignition back on….little things like exhaust manifolds be cracked or separated, engine fire, etc.  Ever going roaring down the road and shut the switch off in your car then switch it back on?

Another problem that could pop up would be a runaway prop on restart.  These are quite stimulating.

In a general aviation light piston airplane it is a pretty simple thing to do an air restart.  With the bigger, higher performance engines used in combat aircraft it just isn't quite as simple all the time.

I think the problem with one player shutting down the engine in middle of combat is that the other player is trying to blame somebody for not realizing early enough that he was going to overshoot engine on or off anyway.

I was actually referring to the starter (which was key controlled in the majority of aircraft I've done air restarts in) to help start the rotation on a completely stopped prop, if necessary. Obviously it wouldn't be necessary if it was still windmilling.

We had one student pilot start the engine on the ground, then kill it with the mag switch while leaving the fuel pump running, and then immediately try to restart. He all but flooded it, with Av LL trickling onto the tarmac. He got a serious talking to about procedures after that.

It is not in any way complicated in most real planes. I've done it in real life while inverted before (was on wrong tank). I would also bet on long missions it was the norm for most pilots to have the engine stop producing power after a tank goes dry.
