Doesn't anyone ever just add power gradually so as not to induce vertigo or precipitate an "unusual attitude"? It's called flying the airplane.
If no visual reference at DA you need to make the a/c go up - in the A330 the AP will only do that if you select TOGA thrust. If you "nearly" select TOGA it keeps going down, while accelerating.
Manual flight - you still need to go up to avoid busting MDA - and the FD is switched to G/A mode by selection of TOGA.
So you cannot add power gradually in this instance.
