Does height advantage change an ordnance weapon's Targeting roll or only its Fire Attack?

Question

Accepted Answer

Only the Fire Attack. Height changes FP by 1 for any weapon, ordnance included, and the designer chose an FP modifier over a targeting-range modifier. An Artillery Requested impact takes no extra hill penalty.
