When they converted to SH-2G, and the CG changed a bit, that variant had a nearly level flight attitude. (Made night deck landings a lot easier, according to the TP's who flew it). | |

The horizontal stabiliser is designed to produce an upforce on the tail which levels the nose in cruise. Actually, everything I've flown is slightly nose down at anything much above translational lift speed anyway. Additionally, the rotor attitude has little to do with the stable state of the deck since the fuselage acts as a pendulum hanging beneath and will swing back to it's stable state. In cruise, helis are statically stable but dynamically unstable. | |
