Flight Control Platform
The Flight Control Platform area does not contain an island, but does contain a minigame, a submarine, and sunken treasure.
Minigame
This area contains the Bird-Man Contest in which the player has to fly a long distance from the platform to the flags on the other side of a runway using the Deku Leaf. There are updrafts the player can use to prevent themselves from falling into the sea. The player will need to have Double Magic to win this minigame. In the vanilla game, the player will receive a Piece of Heart.
Submarine
The submarine is located south of the platform. This is considered the most difficult submarine due to the combination of the Wizzrobes and Miniblins that will consistently regenerate, causing the player to have a difficult time targeting the Wizzrobes. Once the player defeats all of the Wizzorbes and any enemies they created, the back room will be accessible by a ladder containing a chest that is the Platform Chart in the vanilla game.
The player may skip killing the Wizzrobes by leaf pumping from the entrance to the back room of the submarine.
Sunken Treasure
This treasure can be accessed by opening Treasure Chart 19 when charts are not randomized and contains the Heart Chart in the vanilla game.
