HiI have a weird situation, If I choose to use the right seat for a cold start the ND and PFD are blank until engine start, whereas the left seat ND ad PFD work fine on the APU or GND power.Anyone ?thanksSteve

Steve,A qualified guess:DUs electrically fed from different buses perhaps? For redundancy.Cheers,

Would you be able to take (and post on the forum) a screenshot of your electrical panel and ELEC Syntoptic when you have this problem?Cheers.Q>

HiLast night it was OK, I didn't have much time to investigate, but I think in the past the ssb may have been open.I will post back with a screenie as you suggest, if it happens again and the power seems to be ok.Many thanksSteveps - I am alone here, I much prefer the right seat (for 2d view) you get the Eicas buttons :-)
