Raptoran Flight

Gliding (Ex): A raptoran can use her wings to glide, negat-
ing damage from a fall of any height and allowing 20 feet of
forward travel for every 5 feet of descent. Raptorans glide
at a speed of 40 feet (average maneuverability). Even if a
raptoran’s maneuverability improves, she can’t hover while
gliding. A raptoran can’t glide while carrying a medium
or heavy load.
  If a raptoran becomes unconscious or helpless while
in midair, her wings naturally unfurl and powerful liga-
ments stiffen the wings. The raptoran descends in a tight
corkscrew and takes only 1d6 points of falling damage, no
matter what the actual distance of the fall.
• Flight (Ex): When a raptoran reaches 5 Hit Dice, she becomes
able to fly at a speed of 40 feet (average maneuverability). A
raptoran can’t fly while carrying a medium or heavy load
or while fatigued or exhausted.
  Raptorans can safely f ly for a number of rounds
equal to their Constitution modifier (minimum 1
round). They can exert themselves to f ly for up to twice
as long, but then they’re fatigued at the end of the f light.
Raptorans are likewise fatigued after spending a total of
more than 10 minutes per day f lying. Because raptorans
can glide before, after, and between rounds of actual
f light, they can remain aloft for extended periods (even
if they can only use f light for 1 round at a time without
becoming fatigued).
  When they reach 10 Hit Dice, raptorans have enough
stamina and prowess to fly for longer periods. They can fly
at a speed of 40 feet (average maneuverability), and flying
requires no more exertion than walking or running.
  A raptoran with flight can make a dive attack. A dive
attack works like a charge, but the raptoran must move a
minimum of 30 feet and descend at least 10 feet. A raptoran
can make a dive attack only when wielding a piercing
weapon; if the attack hits, it deals double damage.
  A raptoran with flight can use the run action while
flying, provided she flies in a straight line.
