The quest "Supply-Eyeing Fliers" can be discovered in the South Tabantha Snowfield, just off the road leading south from the Snowfield Stable. This quest becomes available only after the player has cleared the Wind Temple and the quest "Tulin of Rito Village" in The Legend of Zelda: Tears of the Kingdom.
To reach the quest area, the player can teleport to either the Orochium Shrine, which is near the stable and slightly north of the quest area, or the Nouda Shrine, which is much closer to the destination though is underground in a cave. Alternatively, the player can fast-travel to the Pikida Stonegrove Skyview Tower and glide far to the south. The map below notes the shrines for landmark purposes only, they are not involved in this Tears of the Kingdom quest.
The player should head toward or follow the road leading through the Snowfield, heading towards the Tabantha Hills region. This region can become extremely cold, necessitating the use of proper armor or 
Cold Resistance consumables. When the terrain becomes hilly on both sides of the road, the player should climb a short stone hill to the east of the road.
There is a small structure near the road with two stone statues, indicating a Korok puzzle. This is the point where the player should veer off the road. Their destination is located at coordinates (-2172, 2027, 0363), on top of the tallest hill. A signal fire is burning on the hill, and the player should be able to spot the smoke to confirm they are heading in the right direction.
To solve the Korok puzzle, head just a bit further down the road to find a pile of wooden planks. Grab the largest plank with the Ultrahand, return to the statues, and place the plank atop the wooden frame to create a roof over the statues.
Upon reaching the hilltop, the player will encounter Huck, a frustrated Rito who is gazing at the sky. Huck has been attempting to transport supplies from Snowfield Stable to Rito Village but was hindered by flying monsters who stole the supplies. The monsters he refers to are a group of three Aerocudas circling his encampment at a high altitude.
Huck is unsure how Link, who cannot fly, will be of assistance, but Link proves to be resourceful thanks to his new abilities. Unfortunately, there are no nearby Skyview Towers or Sky Islands from which Link can glide and dive to reach and eliminate the monsters. However, there are two methods the player can employ to defeat the troublesome Aerocudas and recover the stolen supplies.
The first, and most simple, method utilizes Tears of the Kingdom's new Fuse ability. This mechanic allows Link to fuse monster parts and other materials to weapons and arrows to gain additional benefits in combat. To easily dispatch the Aerocudas, Link should fuse a Keese Eyeball with an arrow. To do so, the player should pull the bow then press up on the D-Pad to select the item to fuse. After fusing any 
Keese Eyeball to an arrow, Link can aim toward any of the Aerocudas directly above and release the arrow. To really send a message to these pesky monsters, Link can also use 
Aerocuda Eyeballs to achieve the same result.
The fused arrow, guided by the Keese Eyeball, will automatically home in on the enemy and bring down the Aerocuda from the sky. This method does not require a specific type of Keese Eyeball or bow, nor does Link need to employ precise aim. This is by far the easiest method, assuming the player has Keese Eyeballs in their possession, to complete the quest.
The second method involves utilizing a Hylian Pine Cone, a sort of "secret weapon," capable of creating a massive updraft when ignited. The player should grab a 
Hylian Pine Cone from their inventory and drop it into Huck's campfire, causing the updraft to form. Link can then jump and use his paraglider to ascend high into the sky, getting closer to the Aerocudas. Aiming the bow while airborne will slow down Link's descent, making it easier to take aim. Again, using a Keese Eyeball will ensure his shots hit their mark, but if the player has Keese Eyeballs available, there is no point to not remain on the ground in the first place.
Defeating the Aerocudas does not yield any special quest items for Link to collect; only regular monster part drops will be obtained. Once all three Aerocudas have been defeated, the player can speak to Huck, who will express his profuse gratitude and reward Link with 50 Rupees.
