  •  Only in a dire emergency (22+ / 0-)

    United 232 (DC-10) was crash landed at Sioux City Iowa using only the engines to steer after suffering total hydraulic failure.

    A DHL Airbus 300 was hit by a missile while flying out of Baghdad and did the same.

    Each engine has its own throttle so that you can keep the thrust balanced (they're never rigged exactly equal).

    That's also how you would shut one down if you needed to - if you lifted up on the throttle you could bring it all the way to "off".

    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!

    •  And not always successfully (8+ / 0-)

      There was JAL 123(747-146SR) that lost most of its tail due to a faulty repair of the aft pressure . The crew tried to fly the aircraft engines on engines for nearly 20 minutes before it slammed into a mountain in the most deadly single aircraft crash. Without the tail, the plane went into a dutch rolling motion that was nearly impossible to control.

        one of the crash victims on that flight.

        The wikipedia entry on JAL 123 describes the plane as being in a phugoid or porpoising motion due to lack of pitch stabilization because of the tail damage.

        The doomed had a half hour to write final thoughts to their survivors.

          I was just reviewing Macarthur Job's excellent article on the subject. Basically, the complex motion of JAL 123 consisted of a combination of a 90 second/20 degree phugoid cycle in the which the plane would have Dutch rolled no less than 7 or 8 times.

          The time of flight was about 32 minutes from the problem to the crash in which the crew desperately tried to regain control with engine power. They actually managed to damp out the phugoid by lowering the undercarriage and to get the plane turned back toward  Haneda at one point, but there was no way they could sustain level flight long enough to make the 35nm back to the airport. Then, everything turned back to complete crap as they tried to dodge mountains and set off the phugoid again.

          Some pretty heroic stuff there.

      has always been the most riveting plane accident I've ever heard about.  The heroism of the crew members and the good bit of luck they experienced--along with the horrible bad luck of losing hydraulics--never ceases to amaze me.

      Thanks Major Kong for all these diaries.
