My point is more that anything can happen, but for someone trainig for a multi engine license just focus on the events that are more common (engine failures, unscheduled feathers, prop overspeeds), instead of trying to logic solutions to the rare, almost unheard of situations.
Oh yes, I'll buy that. But what I won't actively discourage is someone asking about how the heavier metal works if that's their eventual goal.
Each rating has three spheres of knowledge:
- Need to know (if you don't know this, you'll bust)
- Nice to know (the examiner will probably expect you to know this, and if you don't know it, you just might bust)
- Trivia (if you want to impress your examiner, but you DO NOT need to know it, and especially not at the expense of the above two—oh and if you do try to impress the guy, you'd better be right)
(This is the part where someone points out that I'm not a CFI, but that doesn't mean I'm not right about the above.)
Granted the Bro conversation above is pretty far off into the weeds, but the principles of aerodynamics that OP is asking about with the drag from a prop not feathered are the same whether or not you're flying a Seminole or the Spruce Goose. And losing prop control isn't unheard of on a GA airplane (prop cable breaks, whee) but it's usually not as huge a deal either.
