747-400 INS Alignment problem

[Guest 737767]

Hi,in the 747-400 I start from a cold and dark situation. After inserting the GPS position into LSK 5R I get the message "insert INS position" twice, as I had moved the aircraft from another airport. That

The way I understand it, and it seems to work for me, if I've moved the aircraft since the last flight, I always have to input the current GPS Pos in LSK5R twice, whether or not the INS has finished spooling up or not. Just down-selct the current GPS to the scratchpad, up-select it to LSK5R. Press CLR to clear the scratchpad, Then repeat. When the INS is done spooling, you should be good-to-go. Hope this helps...
