This is the second story progression achievement.
*** Spoiler - click to reveal ***After arriving at the Zephyr Transit Hub for the first time and speaking to Noah he'll tell you to go see Birdman. Place a marker on the map to find a route to him. When you get to his location press A to begin a conversation with him. He'll send you to a dash location - get to this location then complete the dash within the time limit. Upon doing so you'll unlock this achievement. If you fail to complete the dash within the time limit you can retry until you get it, but it's not too difficult so shouldn't cause too many problems.
