You have an enhanced jump ability. If you haven't already, go into your Striker class menu and make sure that the ability is active. If it is, then the circle that represents it will be blue with a white picture inside. If it is not, then the circle will be an outline in green with a white picture inside.

If you mean the item for titans that allows for more directional control in air, see Twilight Garrison.
