Sideslip causes your aircraft to roll once to the right or left (in aircraft which cannot roll, you simply slide). Similar to barrel roll in appearance, sideslip consists of only a single roll, occasionally making it difficult to discern the difference between sideslip and barrel roll when an enemy first begins a rolling maneuver. Sideslip is also one of the few combat maneuvers that almost all planes can perform (including blimps, but excluding the Leviathan), and the only such maneuver that reduces silhouette to raise the plane's dodge chance.
