The Flight Control Platform is the site of the Rito Tribe Bird-Man Contest, a minigame that tests your ability to glide with the Deku Leaf. Until you have the Deku Leaf and Magic Meter upgrade, you can’t do much at the Flight Control Platform.
Platform Chart (via Submarine #3)
The Platform Chart reveals the locations of all Sea Platforms across the Great Sea, and it’s stashed inside this sector’s submarine. Sail to the submarine, climb onto it, and enter the doorway leading inside.
Everything is dark until you step on a pressure switch on the floor. The sub’s torches light, and several enemies attack you. Defeat all of the Wizzrobes, ChuChus, and Miniblins to make a ladder drop from the ceiling. Climb the ladder to reach a treasure chest, which contains the Platform Chart.
Piece of Heart #10 (via Bird-Man Contest)
In the Bird-Man Contest, a fun and challenging minigame, you must use the Deku Leaf to glide as far as possible. It costs 10 Rupees to play, but the prize makes the price seem trivial.
A long, roped-off area extends from the launch deck of the Flight Control Platform. At the end of the area is a banner marking the record-setting distance that the Bird-Man Contest’s “Great and Talented Champion” glided to. If you make it past the banner, you become the new champion.
Because gliding with the Deku Leaf constantly drains your Magic Bar, you don’t stand a chance without a Magic Bar upgrade from the Great Fairy in sector D7. Use updrafts to give yourself the extra altitude needed to make the long glide to the banner.
Before you rush off the Flight Control Platform’s takeoff ramp, study the movements of the updrafts. If you time it just right, you can jump and glide straight toward the distant banner, catching an updraft or two along the way. If your timing is off, you waste time and momentum attempting to steer into an updraft.
With excellent time, you easily cross the banner at the other side of the roped-in area. For beating the previously untouchable record, you get Piece of Heart #10. You can play the Bird-Man Contest minigame as many times as you like. Each time you set a new record, you get a Purple Rupee prize.
Island Hearts Chart (via Treasure Chart #19)
Find and open Treasure Chart #19 (found at the Four-Eye Reef [A2]) to pull a chest from the Great Sea near the Flight Control Platform. The chest contains the Island Hearts Chart, which reveals the locations of all Pieces of Heart that are not found by using Treasure Charts.
