Hi Paul.

Sorry if I have confused you. It's like this:

Single INS = No realignment in-flight = I can't get it to work. But I could be doing something wrong.
Dual INS = I CAN realign it in-flight = I can get it to work as it says in the CIVA-INS documentation.

In the KSEA - PHNL when I got within range of the VORs I couldn't get the INS to realign so I was quite a few miles off my chosen course/waypoints.

I hope I have cleared that up for you.

Mark
