@ I-2021
We still need Hyd actuators to move the surfaces (G/Y for THS and G/Y/B for Rudders). This is unlikely in this scenario. However, if you have Hyds going, the Bus can be flown. I actually managed to "get her down" on one of the two occasions attempted during sims.
@ Last Ditch,
the question raised was about a total loss of electrical power, not hydraulic power.
