esa1178 Posted June 9, 2017 Report Posted June 9, 2017 Sorry if this has already been addressed: I am climbing out of LAX and engage VNAV & LNAV, but AP will not engage.. Not touching controls and controls have been calibrated.. Many thanks! Mark/ESA1178
mmerelles Posted June 9, 2017 Report Posted June 9, 2017 can you make a screen capture of your entire forward panel (or several screen captures of partial areas) to see what the system status are by the moment you try to engage AP? is very difficult to diagnose what problem you are having without any detail other than AP does not engage. I have a clue what could be wrong but need to see you screen captures
esa1178 Posted June 9, 2017 Author Report Posted June 9, 2017 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 ? Mark

esa1178 Posted June 9, 2017 Author Report Posted June 9, 2017 (edited) aha! That was the issue. All fixed... Thanks a bunch!! Edited June 9, 2017 by esa1178
