Quick thinking, James. I think we have modeled the alignment process not working when the airplane is moving. Without engines, the plane shouldn´t move much, unless the ramp is slopey. But I have also seen users that started the engines without the hyd-pumps on, and never realised the brake accumulator was depleted.
That being said, we look into improving charging of the brake accu during reboots - right now a gizmo-reboot won´t recharge it, so you would either have to run the B hydraulic pressure up, or reload the aircraft...
