The choice is easy if you are running a boat load of plugins (Latitude, AirHauler, FSFlightKeeper, FSPassenger) in tandem with you weather engine. One works without a problem, the other causes wind shifts (that destroy your aircraft).

 

This is why ASN and FSGRW are the ones I use.

 

I tried to debug the problem with the developer, but ... how should it put it ... I got the feeling that the developer was more interested in shouting rather than problem solving.

No, not using ASN concurrently with opus but installing asn for the .dll so the weather radar feature on the PMDG 777 and flightsim lab a320 can be used.

not to sure about this thought you need asn running  all the time  for updating  the weather radar could be wrong though

I used to think that the 4 weather injectors, OpusFXI, FSGRW, REX 3 and ASN were pretty much equal. To me though, ASN produces the most realistic weather without cloud popping and wind shifts.

Huh so what your saying you want to use asn and optus weather together  this cant be done, its either one or the other

All that is necessary to have usage of the ASN weather radar is to have the ASN.DLL installed into your sim which naturally comes with the trial version. Hence, you don't need to actually buy ASN in order to get radar capability. This was proven in usage with the B777 when ASN first released their radar package for an upgraded price.

As stated before. About 3-4 weeks passed I got curious and decided to do some testing between ASN and OPUS again. One big defining difference could be seen just by being on the ground at my initial weather loadup. Metar was reporting winds of somewhere at 290/11. ASN gave me 275/11 and opus showed 290/11. I tried to loadup from scratch at several different airports with more or less the same results.

 

We all know that the FSX code isn't the best out there. One of its many and biggest flaws is the inability of the upper wind to back down from a previous value. Therefore, OPUS uses a terminology called " sim friendly". What this means is the program will take the raw data and limit what gets injected so as to not ###### off the coding and cause a shift. So if the real wind is 295/75 at FL330 and the next level at FL340 is 285/70, using sim friendly it'll keep the 75 over the 70. Turning off the sim friendly results in having the data AS IS. This can be prone to wind shifting.

 

My personal belief is that ASN automatically has this code friendly feature from the beginning in the background software. Would easily explain why ASN users never got the wind issues that OPUS users were getting. The difference in fact is raw data as is vs data that is altered to be sim compliant. Realism VS altered. Your choice.

This is actually a point in ASN's favor. Many people do not realize that the winds in METAR reports are referenced to TRUE north, not magnetic north. The heading indicators of aircraft operating at a specific airport will be using magnetic north as their "zero" reference, which will differ from true north by whatever the local magnetic variation might be. Likewise, the published runway headings are referenced to magnetic north.

 

So, if a particular airport has a magnetic variation of 15 degrees west, the actual wind direction could indeed be 275 degrees (magnetic) even though the METAR reports 290 degrees.

 

If you were listening to that airport's recorded ATIS broadcast, they would report the wind as 275 degrees.

 

It appears that ASN automatically applies the local magnetic variation to METAR wind reports.
