Pure B.S. The AH-64D's are all outfitted with the newer and better performing GE 701C engines. Hover height is more of an equation of ambient conditions (PA/DA/wind speed and direction with relation to the aircraft heading) and gross weight of the aircraft. Bottom line: the AH-64D has all the power it needs to maintain a steady hover Out of Ground Effect (OGE), carrying a standard weapons load, for all but the most severe conditions.
