Thank you mmerelles for your fast reply..
In fact it looks as though the IRS are still not aligned..
I returned to the runway. And switched the IRS to off, waited until ALIGN extinguished.
Switched to ALIGN then went to POS on FMC and used KLAX as the ref airport copy & pasted POS to SET IRS POS.
Finally switching IRS switches over to NAV.
But AP will still not engage.
I suspect that the Align IRS is the issue...
Does the IGEX 737 Align instantly ?
