Aerial Challenges

There are two categories of Aerial Challenges that contribute to 100% completion of the game. The categories are Under the Bridge and Knife Flight. There are 53 Under the Bridge challenges, but only 25 of these must be completed to go toward the 100% goal. And only 8 of the 15 Knife Flights need to be completed. Continue reading to find locations for completing all the Aerial Challenges.

Knife flights
If you've explored the Flight School challenge, you may already be familiar with what a knife is and how to pull one off. If not, a knife is when you roll the plane on its side so the wings are vertical with the horizon. To mantain altitude while in a knife position, activate the opposite rudder to keep the plane from losing altitude. If you rolled to the left and are trying to mantain a left knife, apply the right rudder. The opposite is true for a right knife.

Perform these Knife Flight Challenges while in a slow plane such as the stunt plane or a biplane like a crop duster, which can be stolen by watching Trevor's McKenzie Field air strip (they often land there). Jets require more room for small small direction changes and are not suited for some of these more difficult Knife Flight challenges.

Under the Bridges
Under the Bridge challenges can be completed in any aircraft. However, some aircraft types are easier than others, depending on the bridge or series of bridges. This section identifies half of the 50 Under the Bridge challenges. A successful Under the Bridge execution is when the ground or water beneath the bridge and the bridge itself are untouched as you pass fully underneath.

Trevor is the logical character of choice for completing these challenges since he is the best pilot and is often near a landing strip or helipad where aircraft can be found. However, any character can do them. Find helicopters taking off and landing at the purchasable helipads (in Vespucci). Find planes of all types at the airport or taking off and landing at McKenzie Field (Trevor's airstrip). You can also purchase planes and helicopters online (elitastravel.com), as well as military helicopters on warstock-cache-and-carry.com. The Buzzard Attack Chopper is a must have.
