The normal charge responses can be made against a diving charge (stand and shoot, hold or flee). Stand and shoot responses are made at the maximum range of the weapon (as is normal for charges from beyond a weapon's maximum range).
If an enemy flees from a dive then the attacking model is placed in its nominated position and may move no further. The flying model does not chase the fleeing enemy and is considered to have expended its entire movement by diving. Troops fleeing from such an attack will therefore always escape. Preferred targets for dive attacks will therefore be enemy already engaged in combat, or static targets such as war engines (whose crews may flee none-the-less).
