I want to move the sprite in the direction it's rotated.

C#

if (newState.IsKeyDown(Keys.W))
            {
                airplanePos += new Vector2(Convert.ToInt32(Math.Sin(airplaneAngle * 360)), Convert.ToInt32(Math.Cos(airplaneAngle * 360)));
            }

It doesn't move in the right direction, I guess the direction calculation is wrong.

I BELIEVE it should be like this, although I haven't tested it:

C#

if (newState.IsKeyDown(Keys.W))
            {
                airplanePos += new Vector2(Convert.ToInt32(Math.Cos(airplaneAngle * 360)), Convert.ToInt32(Math.Sin(airplaneAngle * 360)));
            }
