Canyon flight

A recurring gameplay feature in the Ace Combat games, a canyon flight refers to any instance when the player is forced to pilot their aircraft at very low altitude through a series of canyons or ravines in order to avoid intense enemy anti-aircraft defenses blanketing the airspace above. Unlike tunnel flights, canyon flights typically occur at random points throughout the games as opposed to at or near the climax of the storyline.
