Please sign with real name in this forum.Don't enter the postion lat/lon until it is ready. There will be empty boxes on the line where that info goes. Copy it from the GPS postion line.So here we go:Switch to OffSwitch to NAVWhen alignment is done, the CDU says something like set irs.Copy GPS postion to scratch pad, press RSB on bottom right to past to irs.Sometimes it will want to do this twice.All of this is from memory, which in my case is very unreliable.Just ensure aircraft is not moved during irs calibration.

If you are working in the Virtual Cockpit, I have noticed I always have to enter it into the right FMC even after entering it into the left.
