Shutting the fuel off? Wow. I can only imagine it takes some time for it to get back through the lines and to the engine. I was only asking because a teacher once showed us some videos they had done for class and he told us how he had turned the engine off on his students which he now considered wrong. However I've heard of other places that prefer getting you over a field and shutting it off for training purposes. I guess you are just a glider then really.

Another reason I ask is because I've had two failures on me. One partialy my fault and the other was not. The partially one was a broken fuel cap when I was a student. I didn't know what to really look for which now seems like common knowledge. The second time however was flat out failure in a poorly maintained piper tomahawk. I followed the checklist to the T on what to do and it failed. There was nothing that mentioned what to do if the prop had stopped spinning which it had for me. I was flying high angle of attack and slow doing radio relay for the oil field when it hit. Took all of one second to stop it.

Anywho I started to go through the procedure and when I hit the key it did nothing. I tried it several times and nothing. I then just did what I do in a twin and that's nose it over for around 115kts and got it spinning again to recover. It didn't hit me till on the ground that perhaps I had to take the key and move it to the off position before trying to start it from the "both" position. To "reset" it perhaps? I'm no mechanic. Just thinking out on that one. Plane ended up having an issue that once the wings got so cold at the higher altitudes that there was enough play in the rivets that it leaked the fuel out of the left tank. The indicators apparently were not working well.
