Hello guys,

 

I am about to purchase the flight planner PFPX. Reading the instrucctions, It cought my attention that some of the weather patterns used in PFPX are downloaded from a central server. For those using ASN, how will the weather information interact between each other, does for example PFPX calculates winds based on ASN?

 

Thanks   

PFPX can grab weather info from most weather addons, ASN, FSGRW. PFPX gets it's weather from NOAA, so that is the weather you will get in your flight planning. So you would use NOAA if you were using Opus.

For ASN users, it is just a case of selecting AS in the weather options ( settings ) It is self explanatory once you see it.

It's very easy as said above and works great pfpx is one the most in depth things I've ever purchased.

Bear in mind that for the first 12 months you can access the NOAA weather servers as it's included in the price of PFPX.

 

After 12 months you either have to purchase another year's weather access (around $11) or use an alternative such as ASN.

For those using ASN, how will the weather information interact between each other, does for example PFPX calculates winds based on ASN?

 

It doesn't need to interact at all. Even if forecast is a little bit off it's still way more precise than IRL.

 

Weather forecast is just an educated guess. Yes, meteo offices collect as much data as they can, they use supercomputers to process collected data and output plausible scenarios. They use human brains to select the most plausible scenario. They publish their forecasts for fixed time point every six hours, and everything between those 6 hours is interpolation at the best and god knows what at the worst scenario. 

 

 

There are only two meteo offices in the world capable to do such a thing, and provide data to pilots. Now, whatever weather engines for FSX does, they end up using data provided by those two centers. Simply, there is no other source if you want to cover whole world.

 

To conclude, since FSX weather engines use the very same prognostic charts for their calculation as pilots/dispatchers use in planning, injected weather lacks entropy that exists in real world, so the difference between prognosticated/injected weather in fsx should be very small.

 

EDIT: Just to add: If you compare forecast charts from those two centers for a same area and for a same time and disregard different chart projections and other technical differences, you'll probably find a relatively small difference in forecasts. It's that inconsistent.
