This brings up the question: How do you know the engine was running?
Just because the prop is turning doesn't mean the engine is running.
Typically the prop doesn't stop until well into the roll out even with
a dead engine...unless the engine seized. Of course if it's digging
into the runway it stops pretty quick unless the engine is developing
power.


You should be able to stop the prop by pulling the mix, and slowing the
aircraft to just short of a stall.


I think you will find you would have to pull up and stall in a rather
steep attitude to get the prop to stop in many planes. In a well
loosened engine on a 150 or 172 it might not stop until well into the
roll out. The prop on the Deb with that 260 HP windmills down to some
where between 30 and 40 MPH which is well below stall speed. Of
course once it's stopped it takes a whale of a lot more speed to get
it started again.:-))
