When using the Captain Sim 767, whenever I try to align the IRS, something goes wrong and on the PFD, where I should see a light brown half-circle for the ground and a light-blue half circle for sky I see dark red for ground and dark blue for sky. Whenever this happens the autopilot does no work properly and therefore I can't fly. Can someone send me a easy way to correctly set the IRS and get normal colors on the PFD and correct autopilot functions.

I know I may not have explained it in a good way but I hope you understand.

Thanks in advance, John

Maybe you are using the wrong method to align the IRS. See this Topic: irs selectors problem
