Hi all, was just wondering if anyone else had the same problem as myself and have a fix for the NAV Lights not working after awhile on the PSS/POSKY Merge 777 300. When flying a trip between YSSY and KLAX i noticed the NAV lights had ceased to work and I could not turn them on again, i simply had to reload the aircraft for them to work again but not 10 mins later the same problem arrised. Can anyone help?
