GF: okay so imagine glideslope intercept altitude and transitioning to a 3 degrees decent on it... something more simple and static.
Would lowering the nose to roughly 2.5deg nose up and reducing thrust appropriately give you an airbus style auto trim or rather a trimmed configuration as you're already trimmed for VREF+5 (let's say you called for landing flaps just a bit before GS intercept and got it trimmed in time for the new speed)
In other words, when minimizing the difference between Trim Ref Speed - Current Speed to 0 do you get only the C* pitch maneuver.
