Pitch vs power....... the answer is both until one has come to a limit. Any change in one will require a change in the other.

Generally in the jets to fly a app I use thrust to speed and pitch to glideslope. An example would be once below glide slope and on speed the flt director would show a pitch up, not a thrust increase with autothrottles. As the airspeed decreases the thrust is then increased by the autothrottles.


On a small much more thrust limited prop flying a visual approach I find that I use the opposite.
