Aileron Roll
For your plane to perform the aileron roll you swipe to the left or right. The aileron roll is your basic evasive maneuver and is very important when lining up bombs and missles. You will find that trying to control machine gun fire while performing this maneuver can be very difficult.
Upward Somersault
To perform a basic upward somersault you must swipe up. This maneuver will turn you the opposite direction of where you were originally facing. The Upward Somersault is much faster than doing a wide turn into the opposite direction.
Counter Maneuvers
You will only be able to do counter maneuvers in PvE mode. To perform a counter maneuver you must swipe back towards the direction of the enemy ship after executing one of the above defensive maneuvers.
