| 1334665 | 2013-03-31 08:48:00 | Little twin engined aircraft have a bit of a problem without one engine. They don't have one to act as a spare, any more than a motorcycle has one spare wheel. Sadly, if you lose one, most of the time and you will fall down. | R2x1 (4628) | ||
| 1334666 | 2013-03-31 09:39:00 | Esp those DH Dominies and Dragonflys they couldnt hold height on one engine even if there were no pax onboard. | prefect (6291) | ||
| 1334667 | 2013-03-31 18:37:00 | Principle function of the 2nd engine is to ensure you reach the scene of the accident following failure of the other . . . | R2x1 (4628) | ||
| 1334668 | 2013-03-31 19:18:00 | RIP Eric Thanks for bring us 2 Degrees and lower prices for all. Lets hope our Air New Zealand pilots do a bit of training on flying those big jets on one engine! |

Nice read though, just wondering though. Once you had gone through a quick troubleshooting checklist for the failed engine, would you not attempt to restart? Or is that generally a rather bad idea. |

You dont restart engines that are leaking fuel and you dont want to be too engrossed in trying to restart at the expense of getting your **** together for the forced landing. One of mates was crossing Cook Strait in a microlight it was a Rotax 503 (aircooled) engine and it seized. Just as he was about to ditch he gave the starter one last pull and away it went and he put it down in a paddock near Rarangi after crossing the sea. |

Losing an engine in a light twin is something I practised with students over and over again until CAA said that it wasnt necessary to do so many. One or two is plenty to get the idea. (Tui ad here) I stopped training on twins after that remark. Instructors are taught to fail an engine by reducing the power slowly on one engine to avoid harming the engine. Not very realistic. In real life it doesnt always happen that way. I have had several engines quit in my lifetime and usually it stops with a bang, or the other extreme it just runs very rough. In the Baron going from symetrical thrust to losing 300hp on one side can cause a pretty violent and frightening yaw. Running rough can also be a bit off-putting if you havent experienced it before. I can tell you the first reaction is to c**p yourself. However practice and practice and practice makes perfect and unless you are just airborne there is no reason to hurry. A light twin loses 85% of its thrust (Not 50%) when an engine fails but even with this the loss of height is not rapid. You first action is to counteract the yaw with a lot of rudder, then identify the dead engine which is not as easy as it might sound. Even experienced airline pilots have been know to mis-identify the failed engine. The procedure for an engine failure at cruise altitude for us old timers is, maintain control, identify, verify, think. An engine failure soon after take off is completely different scenerio and the procedure is a bit a bit different and very critical. At this point most students have been taught to feather the prop on the dead engine.Why? If there is still plenty of height and the aircraft is under control have a look around while maintain control to maybe identify the reason for the engine quiting. It could be as simple as a fuel pump failure or running a fuel tank dry.( There is a procedure for checking the reasons) Some can be rectified easily and with the engine still windmilling it will come back to life very quickly.(watch the yaw) Emergency over.Sometimes trying to restart a stopped engine can be difficult. This rant comes about because I hate to think that a fatality has been caused once again by poor instructing. The loss of a pilot is to me like losing a family member and my condolences go out to the pilots family. VMC means Visual Metrological Conditions. The correct term is Vmc.Velocity minimum control. Ron Machado's article is good if you are over land. Twin engine aircraft do lose both engines but very rarely at the same instant so you can be dealing with a single failure then a minute later a double failure. |
