Couldn't agree more with RAT 5. The simulator's ability to reset should allow the ability to knock out 10 or 12 repetitions in 20 minutes. Instead, we spend half the time trying to figure out why the sim didn't reset to the correct snapshot.
The 2 engine go-around, in real life, comes with baggage: in half the cases, your initial perception is that you yourself have screwed up...too fast, too high, not configured, etc. This is an incredibly powerful distractor to be occupying your residual attention while you're flying the most under-practiced of normal maneuvers.
In the other half of the cases, you've just been handed a can of worms...gear unsafe, no visual references in sight, etc...something that means your day just got more complicated. Another strong distractor.
Either way, you have just injected yourself into the ATC environment as a loose cannon. Lots of radio traffic at just the wrong time. First thing ATC wants to know, about the time the wheels are coming up, is what was the reason for the go-around? Seriously? How about we just fly the airplane for a bit, and discuss the paperwork later.
So this is actually a maneuver fraught with risk for a dozen reasons. The simpler the procedure, and the more we practice the muscle memory, litany, etc., the easier it will be when we need it.
