    I was watching this a couple of days ago.

    I was wondering why the engine was shut down and restarted halfway through?

    Got to love how cell phone cameras bend those blades....

      It's possible they were just doing training. In the Air Force, we never shut down engines for practice but I've seen it done in General Aviation. The Russians may not have the same rules.

      Another possible reason could be to save fuel. P-3 sub hunters would frequently shut down one engine to save fuel.

      The plane is probably so over-powered at lighter weights that it wouldn't be an issue.

      If the pilot's good, see, I mean if he's reeeally sharp, he can barrel that baby in so low... oh you oughta see it sometime. It's a sight. A big plane like a '52... varrrooom! Its jet exhaust... frying chickens in the barnyard!

      •  Coast Guard HC130's do it all the time. (5+ / 0-)

        Normal practice on non-SAR patrols is to shut down the two inner engines and feather the props. Saves mucho fuel, and they do restart them from time to time (especially if icing is likely).

        A particular story from when I was in: a KC-135 was on the Honolulu - SFO route when they lost an engine. They radioed an emergency message to NORAD, who called up the Coast Guard in Sacramento for a guardian flight.

        The HC130 lifted quickly, and got out to the KC-135's position, and took up a position alongside. The kicker was the CG pilots promptly feathered two engines and the AF pilots started yelling on the radio, asking if they were in trouble too. "No," came the reply, "we do this all the time."

        Silence from the KC-135...

        And yeah, I know tarantulas don't really act like that at all, so no snarking, this is the internet damnit!

        Probably training, though another reason to shut down and restart an engine would be a post-maintenance check flight following an engine change or prop change.

        As you correctly point out regarding the P-3, we used to routinely shut down #1 (outboard engine, left side) when we were loitering on-station to save fuel.  Depending on the altitude we were working, we might also shut down #4, once we had burned enough fuel to get down to a lower weight.  #1 had no engine-driven electrical generator so that was the preferred engine to shut down.  Flying on only two of the four engines was not a problem, unless you suddenly had to shut one of them down for a malfunction.  Being single-engine in a P-3 is something a crew never wants to experience.

      Often seen in propeller craft video.

      The curved blades are the clue.
