An Aircraft with this Special rule must declare at the start of its movement phase if it will Hover or Fly. If the unit Hovers, it gains +1 to its Ballistic Skill (BS) characteristic and its Movement (M) characteristic becomes 12". Hovering Aircraft units can be charged by units without the Fly special rule, measuring distances to the Aircraft's base. An Aircraft unit that is Hovering does not automatically explode when immobilised. A unit Hovering is no longer hit on 6+ by enemy shooting attacks. An Aircraft is treated as a Vehicle type while the unit is Hovering.
