That sounds like a fascinating example, tell me more. What do you do when the engine fails?
Actually, the second line of his post is what you do next... except when it's minus 20... (or more correctly... as much as minus 20). Just having spent a week in the sim, it was, as always, mind-expanding.
And pull to 176% (only for 5 seconds) on the remaining engine, before letting it down to 160% or less (for 2m30s), then let it down to 140% for the rest of the day. Now you can only fly about 130 knots or so. Tragic.
And lest we forget... steer with collective and beep switches...
