PSXAloft II : new upper wind and turbulence simulation for PSX

Hello Jean-Philippe,

thanks for your reply.

> P3D send magnetic wind and PSX uses true wind (or reverse I do not remember). PSXAloft takes magnetic
> declination from PSX and applies that declination to P3D received wind before injecting the corrected wind within  > PSX. I see in your report AS gives 211@77 and in PSX ND you can see 212@75. That's fine no ?

let have a look at it again. I compared the following


Active Sky: 211° true     / 77 knots
PSX:        212° magnetic / 75 knots

or (same data)

Active Sky: 211° true / 77 knots
PSX:        243° true / 74 knots

or

Prepar3D: 184° magnetic / 77 knots
PSX:      212° magnetic / 75 knots


In all 3 cases I compare the same data (just 3 different software programs) at the same time. But in all 3 cases, I have a difference of about 30° between the wind direction in P3D and the wind direction in PSX.

During that flight I noted that the magnetic variation is also about 30°, so my conclusion was (and is) that I have an "offset" from the Active Sky wind direction in PSX which is about the size of the magnetic variation.

I can propose the following: I take more data from different location on the planet, preferably from locations with a large magnetic variation. What do you think?

This way we can check if this is systematic effect.

Best regards,
  Markus

JP-

With my most recent update to P3D v3.4 I am happy to report that waypoint winds aloft still popluate with PSXAloft II.  Any news on further progress re. FORECAST winds?

Ta!

Hi,
The download link is not working for me. Can anyone point me in the right direction?
Thank you.

Looks like JP's web site is down...
Maybe someone can provide a new link...

The server stays down. I wonder if someone using Dropbox could provide the files?

Hey guys,

try this link. It should be link to v2.1.3. Hope it works, if not I will fix it later this evening (its early morning here :) ).

Hello everybody,

I've just updated the link on the first page. Thanks to andrej for providing the "backup".

Link is working just fine over here. Do you have cookies disabled by default? That might block the DL

It looks like the problem is with IDM... Internet Download Manager...
I am a member of Dropbox and use IDM for all my other Dropbox files, however the post 1 link seems to cause IDM to be seen as unauthorised. When I disabled IDM the download works.

Hello,

Did somebody try PSXAloft with P3D v4 ? I wonder if it is compatible. I don't have v4 yet so if somebody could report it would be very kind.

Kind regards,

joergalv

Affirmative. P3Dv4 + ASP4 Beta + PSXAloft II  is working out of the box!
Didn't test the use of flightplans yet, but a simple 'Connect' gives AS based winds aloft >20.000ft in PSX as expected.

ASP4 = Active Sky for P3Dv4

That's good news. Thank you.

How great to see you active here! Any word on the Descent Forecast Winds working with ExternalSim active?

Hello Carl,

I'm back after one year away from my simulator (home change and its induced work, work, work)  :D

My hardware sim was de-packed and I started re-wiring everything. I also had a (quick) look at PSXAloft. I also have descent forecast page not loading. I don't know why. It worked during testing, and now it doesn't. Maybe not something very important (I hope). I will have a look ASAP.

I'm glad to see some people still use and apreciate PSXAloft. I still want to implement the integration within PSXTools, and then add some new "modules" like ground, cabin simulation,... easier to say...  :D

Everything is in my head, and on some paper. Just need to find time (and energy) for coding. As a C++ beginer, it takes me very long time. But I'm convinced immersive simulation also needs some "extra" like "outside world"/"backstage" simulation. This will be the aim of PSXTools.

Kind regards

JP-

It does a bang up job of winds aloft, so whatever you can do will be appreciated. Good to have you back in the PSX pond :)

Hi,

I quote this old comment of Markus and will comment below :

I was working at the next update of PSXAloft. Descent data link bug is resoved. PSXAloft v.2.2 is released with this correction. Markus, I also worked at your comments (see the above quote). Thank you for pointing this. I investigated and I think I found my mistake. I was assuming SimConnect sent magnetic wind to PSXAloft, but it sends true wind. As we must inject true wind to PSX, I don't need to apply magnetic declination to FSX/P3D winds before to inject data to PSX.

So to summarize :

- Active Sky displays TRUE wind within current conditions window
- FSX/P3D displays MAGNETIC wind when pressing Shift + Z (upper left screen corner), BUT sends TRUE wind through SimConnect
- PSX needs TRUE wind injections from add-ons
- PSX weather window (planet) displays TRUE wind at tropopause
- PSX ND displays magnetic wind (declination applied within PSX process)

So PSXAloft only needs to inject raw data to PSX.

Please go to the first page of this thread to download PSXAloft v.2.2. If you could stress PSXAloft within big declinations areas and report, it would be kind.

Edit : I stressed until 15° declination and I read 209° magnetic on P3D and 208° magnetic on PSX ND. Sounds good ?

Don't forget to install Visual C++ 2017 redistributable before to use PSXAloft v.2.2 (standalone installers provided within package)

Cheers !
