Accelerated Slipstream
I would like to ask an aeronautical engineer a question. Are there any such fellows or ladies on here for me to ask? I don't know how to use this forum yet. To stupid.
I see that I have made it this far, so I'll ask my question. When taking off in an (twin propeller aircraft) such as the King Air b200 and just after rotation, the left engine quits. It is the critical engine, because both propellers rotate clockwise, viewing from the rear. According to eye witnesses the pilot kept the landing gear down and flaps extended. Reportedly it was estimated that he had attained an altitude of approximately 150 feet. It appears that he made a deliberate left turn to get over to the adjacent parallel runway. Eye witnesses said that when he made the turn, it appeared that everything was okay. He leveled out, but just after that his left wing dipped and he crashed into a flight training building. Witnesses stated that the landing gear remained down and flaps were still extended during the turn. Now I have read a great deal about the loss of the lift of the accelerated slipstream produced by the left propeller of the left engine when that engine fails. This loss of lift causes the left wing to drop and because of p-factor of the right propeller accelerated slipstream, this also causes a more dramatic roll to the left, especially at low speeds. Also the added drag of the left dead engine and wing causes a strong left yaw. It is therefor recommended to feather the dead engine asap, raise the gear when you are sure that you have Vmc and than retract the flaps and banking to the right about 5 degrees to correct yaw and roll. I have read that the loss of the propeller accelerated slipstream over the wings is greater and is lost during an engine failure at slow speed and high angle of attack in the take off configuration. However many pilots don't agree with the loss of the accelerated slipstream. My question is it a true factor that could prevent engine failure crashes if pilots were aware of it and know what to do? Or is it that, many people in aviation don't understand this? Do we need better training, not more but better? Three people in a flight training building died as well as the pilot in this accident. The plane had no additional load.
