Paul, are your answers your way of saying "it depends"?
Maybe my question isn't clear enough. (Maybe it can't be clear enough to get a single answer).
1. From level flight, at 50% throttle, you want to climb. What single thing would you do to accomplish that?
2. From level flight, at 50% throttle, you want to slow down. What single thing would you do to accomplish that?
Put another way: What flight parameter or characteristic does the elevator control?
What flight parameter or characteristic does the throttle control?
Maybe I need my head examined.
