Goku is able to use a Tail-Helicopter Technique (尻尾を回転させて空を飛ぶ Shippo Wo Kaiten Sasete Sora Wo Tobu, lit. "Flying Through the Air by Spinning Your Tail") where he swings his tail in a circle fast enough to hover and fly freely. He used it only once, in his fight against Jackie Chun in the 21st World Martial Arts Tournament. Jaco the Galactic Patrolman is capable of high speed flight using his jet boots.
As the androids have no ki of their own, they are unable to use Flight. Instead, they have a special device in their body that allows them to fly, while others have rockets.
Whereas ki-based flight does not function in the Tournament of Power, Hikou can still be utilized, putting winged fighters at an advantage.
Video Game Appearances
In various video games, certain characters such as Mr. Satan that are incapable of ki-based flight are equipped with jet-packs that allow them to fly. This is usually done for gameplay purposes to provide a plausible explanation for how they are able to fly.
Oolong uses a jetpack to fly around during a Sub-Event in Dragon Ball Fusions. Arale Norimaki can use this technique in Dragon Ball Fusions much like how Kid Goku can fly using ki after being transported to the Timespace Rift. This is due to the fact that battles take place in the air in Dragon Ball Fusions necessitating them to be able to fly in some form. It is also used by Android Mecha Goku and Nuova Goku, the EX-Fusion of Nuova Shenron and Goku.
