Light Flight is a light power used by Light Jak during Jak 3, granted when he rescues Seem from the Dark Makers at the Monk Temple. It is the fourth and last light power gained in the game.
Light Flight does not allow Jak to fly indefinitely; only glide. This is activated by holding 
and then activating flight by pressing 
. Jak then grows ethereal blue wings. Gliding can take place by continuously tapping . These taps must be well-timed in order to maintain a steady glide.
There is a bug which in combination with Light Shield, allows Jak to fly indefinitely. You can do this by double jumping with your wings unfold, and while in the air pressing 
+ over and over again in a rhythmic motion. Be sure that the pattern is consistent, or Jak will lose altitude and the flight will sometimes fail.
