"In IMC that might even be a good idea, as pilots may not immediately understand that they have to "kick the ball" since they are so used to have a screen showing the horizon, but not the yaw motion... Also the simulator can not give you the real sensation of the yaw due to an engine failure."
As much as training has changed, the focus moving toward using the automation and away from flying the airplane, I find it incredible to think that pilots are not made quite familiar with engine out procedures.
Nor does it surprise me entirely that the pilots extinguished the wrong engine - but it SHOULD surprise me. The British Midland accident in 1989 is another example, I suppose there are others. But, it anything comes out of this, it should be an emphasis in training. There is just no excuse for letting this go on.
