I've just all of a sudden started experiencing this weird phenomenon occurring with my flights.I choose a night flight setting from FSX options i.e.World,Time,Season,et al and all of a sudden in the middle of the flight,it resets itself loading terrain data,etc and goes back to a daytime setting. Despite repeatedly re-setting to a night setting,it inevitably re-loads the scenery,terrain data,etc and I'm back to a daytime setting.I had the Trial version EFB running in the background.Any ideas? Thanks in advance.

I seem to remember there is an option in EFB to sync FS time to the PC time or maybe UTC (can't remember off the top of my head) maybe this is what is causing your dilemma, you can turn it off in the options somewhere.

Hi Andy.Thanks for your reply.Oddly enough I too had a hunch that was the cause because I was on GMT+1 local time yet had set my departure time for 0100am, at Tampa en route to KJFK,and I vaguely remembered that there was a setting in EFB to sync FS to system time.Will uncheck and retry.
