Before we begin any flight, we input month, day and year. Here's where the questions come. If we have flight plans for a season and year, do those flight plans only work for that season and year? Or, do they work continuously dispite the season and year of the flight plans? My PC can handle all the extra flight plans, I just don't want to have a bunch of un-used files on the hard drive. Thanx for any insites to this. Semper Fi, Dave

My guess is your speaking of AI flight plans you have downloaded/installed that replicate the current real world seasonal schedules of specific airlines. If your intent is 'realism', you would normally replace the flightplan with the next season's flightplan.

There is no data entry within a flightplan (traffic*.bgl) file that controls the year or season, only times relative to daily or weekly periods. If you leave the file in the sim the flightplans will continue to execute, year around.

If your intent is simply to have AI airlines flying year around, the 'seasonal' flight plans will do that.

Of course, if you leave 'old' schedules in while continuing to add 'current' schedules, your airports, and possibly the skys, will eventually run out of room..
