I disagree with this.
Fly: The creature can fly at the given speed if carrying no more than a medium load. All Fly speeds include a parenthetical not indicating maneuverability.
Perfect: The creature can perform nearly any aerial maneuver it wishes. It moves through the air as well as a human does over smooth ground.
Good: The creature is very agile in the air (like a housefly or hummingbird), but cannot change direction as readily as those with perfect maneuverability.
Average: The creature can fly as adriotly as a small bird.
Now when I read and interpret this, I see the maneuverability rating as a rating of Agility, and more specifically the ability to alter direction.
Thus the statement that a "Perfect" flier "
can move through the air as well as a human does over smooth ground" means they can turn on a dime including pulling any angled turn all the way to 360 degree turns in one spot where a normal "flier" or bird cant do that. It would also include hovering which a "Good" maneuverability can also do (humingbird) but no other flyer can.
As it says
"The creature can perform nearly any aerial maneuver it wishes." which to me means it is
incredibly agile in the Air.
A Human cannot do "any land maneuver it wishes" without the need for a Tumble or Balance skill check. A Human with "Pefect" movement would never need make a Balance or Tumble check "over smooth ground".
A Flier that has average maneuverability would follow the same rules as anyone on the ground when it comes to avoiding hazards. They should have an "Average" skill check for such things, thus the +0. Just like ground-pounders get no bonus to phyical skill checks. You can take feats to make you more agile and "Acrobatic" (thus gaining bonuses to skills such as Balance and Tumble, which bring you closer to being "Perfect" in your motion.
So overall it would go (With Average at 0):
Clumsy -8 (or -4 if you want to be easy on them)
Poor -4 (or -2 if you want to be easy on them)
Average +0
Good +4
Perfect +8
Just my interpretation of the rules the way I see them making the most sense. A Perfect Flier can litteraly fly circles around anything - Air or Land based, and deserve the same +8 Skill Bonus that creatures with a Swim Movement rate get to Swimming skill checks.
