For those hoping to get a a little more real world weather showing up in flights, you might have used the FS9 and FSX default real world weather, since their inceptions onto the market until just a year or so ago.
Since then users of both sims have been relegated to use some free and some paid options out there, most FSX users are using Activesky and FS9 users are to use FSRealwx (or any others that work) for the mean time.
They both quite fix the problem of getting info downloaded only after 15mins (default on both sims) and relegate it to whatever you the end user wants. It could be however long you need to wait for weather info to download.
FSRealwx comes in two forms, one for free and one you pay (i think). FSrealwx Lite is a freeware weather program that will work for both sims (check them first as i have forgotten). FSRealwx Pro is a free for 30 days then pay up type of service and weather program...both work and look the same way just one has a limit of 30 days and then you have to pay for the product.Those have worked great in the years past and will continue to work for more years.
I find nowadays many people come into the flightsim community asking what weather program to use, there are only these listed below to use with the assorted sim and program. some of this is confusing as the payware one should be payware and would thus be easier to talk about.
FS9 has FSRealwx Lite
FSX has FSRealwxPro and AS16+ASCA
both of the fsrealwx can be found on their website https://www.fsrealwx.net/
if you want to use the AS16+ASCA go to https://hifisimtech.com/
Hoping that you can get to this, this is a great set of sites and programs to add a little more realism to your sim...
heres hoping that the notification of that these are the only ones you can use for both sim can be given to you...yes there are only two types of weather progras as listed above fsrealwx and as16...check them both out!!
