A vibration in which the movement is up and down, or vertical, as in an out-of-track condition is called what?

Vertical vibration is motion in the up-and-down direction. When a rotor is out of track, the vibration you feel is primarily along the vertical axis as the blade and hub move up and down through their cycle. This distinguishes it from lateral vibration (side-to-side), torsional vibration (twisting about the shaft), or radial vibration (moving toward or away from the rotor hub). Since the description specifies movement up and down, vertical vibration is the best fit.
