Air speed, or lateral air movement, is the rate at which a character can move left or right while in midair in the Super Smash Flash series. Air speed, falling speed, and gravity are all factors in how far a character can recover.
Air speed is often confused with how far a character can travel without landing. Characters with low falling speeds tend to be able to travel farther in the air simply due to hitting the ground later, not due to travelling through the air faster. As a result, characters with higher falling speeds are often perceived as having lower air speeds.
In Super Smash Flash 2, entering the air from the ground such as by jumping will conserve a portion of the character's grounded momentum for their air speed. The rate at which this is conserved is known as the ground-to-air modifier, also called the ground-to-air multiplier.
Air speeds in Super Smash Flash 2
