Tyranitar is not capable of naturally learning Aerial Ace, it is only capable of learning Aerial Ace via TM40 so you will need to find a way to acquire an additional TM40 in Pokémon Ruby, Pokémon Sapphire, Pokémon FireRed, Pokémon LeafGreen, Pokémon Emerald, Pokémon Diamond, Pokémon Pearl, Pokémon Platinum, Pokémon HeartGold and SoulSilver.
