Wilco 737-500, when trying to re-align the IRU, all I get is flashing lights and it never re-sets. Ive tried both the quick alignment and the regular alignment. This is the procedure Ive used:
quick alignment.... turning IRU to ALIGN momentarialy then back to Nav. This is suppose to do a quick alignment.
REG ALIGNMENT...since the quick alignment wont work, Ive tried this....Turn to OFF momentarily then back NAV.This is suppose to give a complete re-alignment but in both cases, all I get are the flashing alignment lights....and it goes for hours without aligning. Does anyone have any other ideas to try to align this? thanks
