I remembered and dug up the link to the AAIB report in to an A319 that had several electrical failures during the climb out of LHR. I know this isn't the same A/C type or identical errors but it makes you think about the challenges the crew may have had, especially with loss of comms, lighting and having to use visual references to fly.
