Weapon and Armor Proficiency: Aerial avengers are proficient with all simple and martial weapons but with no armor or shields.

Flyby Attack: At 1st level, the aerial avenger gets Flyby Attack as a bonus feat.

Momentum (Ex): A 2nd-level aerial avenger learns to use her momentum and weight to her advantage while fighting. If in the air, the aerial avenger gains a +1 competence bonus to damage. At 5th level, this bonus becomes +2, and at 8th level it rises to +3.

Power Dive (Ex): When a 2nd-level aerial avenger makes a dive (charge) attack, she deals an additional +1d6 points of damage if she hits.

Maneuverability Increase (Ex): At 3rd level, the aerial avenger's maneuverability increases by one rank, so that an aerial avenger with an average maneuverability gains good maneuverability. If the aerial avenger's maneuverability is already perfect, this ability cannot affect it. The aerial avenger's maneuverability increases again at 7th level.

Speed (Ex): At 3rd level, the aerial avenger learns to increase her speed by +10 feet. This bonus increases by +10 feet at 8th level.

Death From Above (Ex): Through training and practice, the 4th-level aerial avenger improves her attack bonus while airborne. If in the air above a foe, the aerial avenger gains a +1 competence bonus to attacks. At 9th level, this bonus increases to +2.

Range Increase (Ex): The 4th-level aerial avenger, when making a ranged attack while in the air, increases the distance of any range increment (or in the case of spells that require a ranged attack roll, an increase in the overall range) by 50%.

Swoop (Ex): At 6th level, the aerial avenger learns to make a devastating attack. While flying in a straight line (using a full-round action), the aerial avenger can move her speed, making a melee attack at any foe within reach on her path. For each foe attacked beyond the first, each attack suffers a -1 attack penalty, so the aerial avenger must declare how many foes she attacks before she starts (minimum two). The aerial avenger gives up her regular attacks to take this action. This is an extraordinary ability that draws no attacks of opportunity, even if the aerial avenger passes through threatened areas on her way through the swoop.

Terrifying Shriek (Ex): The loth-level aerial avenger can add a shrill shriek to any swoop attack, causing all creatures within 50 feet of the point of the first attack to make a Will saving throw (DC 20 plus the aerial avenger's Charisma modifier) or become panicked for 1d6+4 rounds.
