Shanx,
In my training over the last 20 years whether it was on the Tristar (L1011), DC10 or a more modern twin; all engine flame out scenarios have been given in a training event leading to relight of one or more engines, with the outcome of a 'normal landing' on whatever engines are recovered.
Certainly on my present type I have practiced double engine failures in the holding pattern at and above 7000' and made glide approaches. I have to add though that these were never part of a training detail, only a personal request to practice. I am glad I practiced these approaches in light of a recent incident though! I am told that giving pilots a loss of all power in the later stages of an approach during a training detail is futile and negative training, as this will only result in a sim crash and not be benificial to the pilot.
I would like to say though Shanx that if you're concerned about this aspect of the training, don't be; engine failures are not big events normally and if handled correctly are a non-entity, just more paper work.
