Short description of the problem:

• flying P3D V4.5 with ASP4  and historical weather with explicit wind directions
• expecting runways according to ASP4 briefing
• P3D reads wind information from ASP4 including "ASP4 wind lock" (locks wind on airport to 6 knots in one direction)
• P2A gives me different runways as it doesn't seem to respect "ASP4 wind lock"
• problem exists since long time but I managed it by "pilot forcing runway"
• now analyzed current_wx_snapshot.txt and found different wind information as in ASP4 briefing

So I thought about updating to ASP3D but want to be sure that this "bug" was fixed in the newer version.
Now what I get from Hifi support:

Quote

The current_wx_snapshot only outputs the raw METAR text we are using.  This does not include any of the synthesis, options, limits or other changes made to actual weather in AS, which is available through other API methods.  This is the same in all versions of Active Sky.
 
The best solution to resolve the issue you describe would be for that add-on to read our specific weather information using our API, instead of the raw METAR text, to include modification by AS including wind lock.  Perhaps contacting them with this suggestion/details would influence that possibility.  We've already done the work to provide this extensibility and would not be able to modify our output (which other-addons are using for raw text as needed).
 
Hope that information helps!

Any chance to get AS weather read from API instead of current_wx_snapshot ?

Or would it be an option to switch P2A from Active Sky weather to SIM weather ?
(What is the difference between AS weather and SIM weather ?
Or is there any if P3D is connected to AS ?)

Unfortunately, that would require a major rewrite of P2A's weather logic.

A better option would be for ASP to fix their software to output the weather they are providing you into a file that can be read by P2A in standard METAR format.  Then, you and other users could just point P2A to that file and the problem would be solved.

I doubt they will do that for me - even if I upgrade from the older ASPV4 to a newer version.

But what's the difference between the SIM setting and the AS-weather ?
What disadvantage will I get switching from AS to SIM (as AS injects the windlock corrected weather into P3D) ?

On the other hand, at the moment, I use "Force Pilot Runway Selection", so I can select the runway according to my flight plan.

Maybe a useful option would be selecting the in-sim weather for departure and approach (or at least departure), then airborne switch to the weather engine data...but I suspect it isn't easily done.
