Hi, I'm new to this forum.Yesterday, I flied with 767PIC from Japan to Honolulu,I faced to terrible accident. When I crossed E180/W180 longititude line, A/P wasdisengaged and both EADI & EHSI were shut off.Also all IRS shows incorrect data(actually N00E000),so I have to quit my flight.I want to know is this already known issue, or no one but only I expereinced? If anyone know the solution of this trouble, of course welcome.Thanks in advance.P.S. Sorry for my influent English.

It's a known issue. If you had waited things out - all systems would come back to normal. There is a fix out there.DSCVA3339

dont worry, it has happened to me too. . .BUTBefore I knew it was a known fix, I was accustmed to dicking with the IRS's to try to get them to realign during cruise. I ended up getting my L IRS aligned, and was able to get some use out of my EHSI an EADI. Ended up making a visual into Auckland. What a joy that was :)

Taku,Have flown the international dateline crossing many times with the PIC767. Just wait it out and all systems will return to normal. The key is don't attempt to adjust anything. Let the system right itself and it should be OK.I fly KSEA to RJAA all the time and it goes very well.CheersBob Johnson

Thank you so much for all who gave me the clear answers
