Using "Time & Season," I can set my flight for January 1, 1939, at 1500 GMT. Now, if I also use "Real World Weather," I obtain weather conditions. But weather for when? Right now, real time? Or January 1, 1939?In other words, does the Jeppeson real-world weather database just provide the actual weather at the moment you access it, regardless of the "time and season" for which you have set your flight? Or not?Example . . . suppose it's mid-summer, and I'm flying out of Austin, TX. Very hot :-). I download "real world weather." But I also set my "time & season" for January (winter). What's the weather going to be? I'll appreciate anyone clarifying the connection (if any) between "time & season," on the one hand, and "real world weather," on the other.Thanks,Gary

I would assume it grabs the current "Real World" weather reguardless of the time and season settings. I doubt they have meteorogical data that far back for the whole world.In any event try thisSet date to 1900, 1950, 2000, and just for good mesure 2010.Grab real world weather on each and if it all is the same I would assume its just grabbing the current data

It's been a while since I've tested this out, but as far as I know it uses current real world weather regardless of time, and certainly regardless of date. (Or as current as they have. Their sources may not be totally current.)If you use an external weather program that grabs METARs and does use time info (maybe set in the weather program itself?) then the data might be up to 23 hours old depending on the time chosen."Let me help you out. You're cleared to taxi any way you can to any runway you see."

Thanks to all who responded. The recommended test bore out what everyone agreed -- no connection between the two.Gary
