In every one of my ME training flights and on every assymetric i did on my CIR initial and renewals all engine failures were by the instructor/ATO using the mixture control. Usually the aircraft folder of a piece of paper or something handy was used to cover the mixture controls so I couldnt get a peek at which donk was going to die. Even the practice failures after takeoff were done with mixture.
Angle of Attack as part of my initial multi engine training i had to do a practice engine failure just before decision speed, just after the nose had come off the ground and a fully feathered landing.
Both the last 2 made me quite nervous. Both the fully feathered landing and engine failure before decision speed were briefed considerably before we left terra firma and they were done within strict guidelines. I can't remember what they were now.
