Also included is a fluid film location annularly between a surface of the stationary journal bearing and a surface of the gear shaft, and a hybrid pad location on the stationary journal bearing adjacent the fluid film location. The hybrid pad has a minimum leading edge angular location on the stationary journal bearing of 31.0° and a maximum trailing edge angular location on the stationary journal bearing of 43.0°.
