INVALID FORCAST UPLINK

Recommended Posts

Just an FYI, I don't load my flightplan into ASN, and the FMC grabs the winds just fine. I to am having troubles with the descent forecast, but I just put them in manually, no biggy.

 

If you don't load a flight plan into ASN then no WX file is created.

 

If the 777 finds no WX file it will get weather forecasts directly from FSX.

 

Since weather add-ons like ASN set the FSX weather only in an area 50-100 NM around the aircraft position and clear the FSX weather in the remaining world you will get wind forecasts only for a few waypoints ahead of you and in most cases you will not be able to get any descent forecasts if the destination airport is outside this range.

 

So, what you are getting is partial weather data for a limited area around your current position.

SOLVED:

Introduction manual page 163-165

In short

STEP 1 :

on ASN this option must be checked

-

STEP 2 :

 

In Your 777 FMC

Go to PMDG Setup > Simulations >Option

Browse to NXT PAGE .. I believe on Page 7 there is an option

FSX PLN FILE FOR WXR :  Which should be set to  > CREATE FILE AND LOAD TO FSX

I have done exactly like you posted. However the issue I am seeing is that during the flight ASN will not update with the current real live weather or if it is updating the current weather it for sure is not updating the ATIS. On a flight yesterday lasting seven hours as I approached the descent point I went to 122.02 to listen to the weather and it was some five or six hours old. It was saying 1445z and it was 2100z. 1445z is when I started the flight and initially sent for the wind via the fmc by having the "create file and load to fsx" selected and the option ticked in ASN. So I pulled up ASN and went to the current conditions screen. It too way way off with the time it was displaying and the weather conditions. But at the bottom of the ASN UI it did show the correct current Zulu time. So what I think happened is ASN loaded up the weather correctly at Dubai at the beginning of the flight. When I requested the winds via the FMC that triggered a fsx flighplan format to be sent to ASN. This in turn allowed ASN to send back the winds to the FMC. But somehow at that point ASN was no longer keeping up with the real time weather as the flight progressed. Somehow the weather for the whole flight based on the fsx plan fed to it at the beginning that allowed the winds to be forecast in the FMC got locked into the sim. Only upon me manually going into ASN, then bringing up the current condtions tab and hitting that refresh button did the ATIS update from 1445z to 2020z. But an hour later it was now stuck on that 2020z time. Now this all happened even though I have live weather selected to update every 10 minutes.

 

None of the above happens if I forgo sending the plan to ASN and instead manually build the route in ASN and just let it run. Then it works like it is supposed to. Any ideas? Think ASN is the issue.

Well thank you sir, that makes complete sense. I appreciate it!

I used the earlier descriped version.

I enter the flightplan manually into the FMC. It then creates a .pln which ASN will pick up and for which it will create an .wx file. This can then be importet for cruise and descent forecast.

Sorry . Change the setting in your FMC to "CREATE WX FILE" and not "Create WX file and load to FSX"

I think on the later option, FMC Assumes that you are using default FSX weather (which is static unless you have checked live weather mode in FSX as well) and loads in WX from FSX which remains the same throughout.

 

If you use "CREATE WX FILE' only it will take the weather from the active weather enginer which would be ASN.

 

Check if this solve your problem

Hi guys,

 

May be simply overlooking stuff but i have reread the manual so many times. (162/163).

 

ASN option set (Auto Load simulator Flight plan)

 

I create a flightplan in PFPX and export the route and WX file to the default locations.

 

The datalink system works perfectly and I get everything set up correctly.

 

However, when I now go into the forecast page and request the winds, i get the topic title error message when trying to load it in.

 

 

After this I loaded ASN with the flightplan, I changed the PMDG>>Options> Simulation pg7 > Create and Load FSX plan to FSx.

 

 

Still nothing, am i going wrong somewhere, or do you think this is a one off and I need to have the above set before requesting my initial datalink

 

 

Alex

That doesn't solve mine, but it might do for Eric.

Hi Pete,

 

You should probably post your FMC settings for reference then.

Alex, can you try the following:

 

Go to ASN-> Flight Plan. There activate "Add Top of Climb/Top of Descent Waypoints to Flight Plan". See if it works now.

This is not true. This option does not control the creation of the XXXXYYYY.wx file that contains the wind forecasts. It controls the creation of an FSX format flight plan file, named WX.PLN.

 

The 777 will use FSX weather only if no XXXXYYYY.WX file is found for the XXXX-YYYY route. If a .WX file exists it will always be used to provide forecasts.

 

The difference between the "Create WX.PLN file and load to FSX" and "Create WX.PLN FILE" is that in the first case the wx.pln file is created and automatically loaded to FSX in order to trigger an automatic loading to ASN, while in the second case the file is not loaded to FSX, therefore you should manually load it yourself into ASN from the ASN flight plan tab.

 

This is all explained in detail in the provided supplement document.

Hi aceridgey.

 

I had the same issue you have reported..

While I was looking for a solution at HiFi´s forum, I found this (copy & paste from there)...

 

"Have you actually navigated to the plan at least once from within ASN itself?? Until you do (that), ASN won't know where the plans are that it should be loading. This is only necessary when using ASN in a networked environment and you only have to do it once after installing ASN on that client machine." -- by Andydigital.

 

This have solved it for me.... hope it helps you too.

 

Regards, Duran.

How did it go with your red eye last night?

Well, it went great for what I am now doing. I use PFPX for every flight to plan. I use ASN (I start ASN prior to PFPX) for all weather/wind aloft data when planning with PFPX. At the conclusion of my flight planning I send the flight plan (which contains all of the wind aloft forecast data for the route) to the 777 flight plans folder and export the weather to the PMDG weather folder (also send it to vatsim preflight site so when I log on with vPilot I just need to fetch it from the server). I save a copy of the flightplan to my Google Drive folder as well.

 

So then I shut down PFPX, keep ASN running and start fsx. Once in the sim and power to the aircraft I use the coroute feature and load plan into the FMC. I then request the wind data and it loads up. Yes I know that doing it this way does not allow you to update the winds enroute but as I understand it the winds aloft forecast is good for quite a few hours. I manually input the route into ASN.

 

So how did the flight go doing it this way? Well after takeoff I pulled up my flightplan in my tablet as it is now in Google Drive. The OFP I use from within PFPX is a replica of the real world Delta one. As such it has the aloft forecast winds for waypoints about every 100nm.I kept comparing what the forecast was to what I was seeing. The winds were never more than 10 degrees off and were within 5kts. Well within what I would term acceptable. This was on a six hour flight. I tune to 122.02 and get the current ATIS and land. The whole flight went perfect and uneventful up until I went into the bedroom and tried to explain why I was getting into bed at 5am. The winds all pretty much matched up as everything comes from ASN beginning with the flight planning. I really see no need to have to update aloft winds as over the course of a flight are they really going to change that much to make a difference in fsx? I don't think so.

Well, it went great for what I am now doing.

 

 

Right now until I can do more investigation this what I am doing. Start PFPX and plan flight. Export info to PMDG/FLIGHTPLANS/777, PMDG/WX, and Flight Simulator X Files. Close PFPX. Start FSX and complete FMC thru requesting wind data on legs page and executing. Now PFPX forecast winds are in the FMC.

 

Start ASN and load FP from Flight Simulator X Files. It will generate a WX file and send it to PMDG/WX. But that's okay because PFPX forecast has already been requested and executed in the FMC. I will never request the winds again during the remainder of the flight. To do so would bring ASN winds into the FMC. I only want PFPX winds in the FMC. ASN will provide the weather I fly thru and that's all.

 

The Descent Forecast can be loaded from PFPX after the route winds have been requested and executed or they can be manually entered when close to T/D by using AWC-ADDS.

 

I don't like starting ASN in the middle of preflight. I think I have a solution by exporting PFPX again after the FP is entered into ASN. This would overwrite the ASN WX files in PMDG/WX but I need to verify this by doing several flights.

Why do you not use ASN for the weather in PFPX during flight planning? That way what you fly through is also the same as what you use to plan with.

That's why I mentioned I don't like starting ASN in the middle of prefight. I am messing around with the sequence of starting programs right now. I will let you know if I come up with anything.

I think this might work now. Start ASN. Start PFPX. Do planning using PFPX and export three files. Load FP into ASN. Send ASN to taskbar. Export three files again from PFPX. The PMDG/WX contains PFPX forecast at first. Then when the FP is loaded into ASN, PMDG/WX contains ASN winds. When PFPX is exported again PMDG/WX contain PFPX winds.

 

The 777 FMC is only going to look at PMDG/WX for wind data. This procedure should make certain that when it looks for data it finds PFPX.

 

This is what I was doing prior to SP1.

 

Have you heard anything from HiFi about ASN not updating?

Yes, they told me to update my fsuipc (apparently I am one version behind) and see how that goes. I don't think the person who is working on the ticket quite grasps the issue at hand. When back home at my computer I will need to direct him to these threads.

This is how I do my planning. Start asn and minimize it. Start pfpx and do my planning. Export one route in pmdg format.

No wx file is exported because that will get created once the fp is loaded into asn.

 

Start fsx request route in fmc and let it do its thing. Once fp is loaded and activated, an fsx fp gets created based on the option in the fmc to create fp and load it into asn. Asn sees this and immediately loads it up and instantly create a wx file based on current weather. Pfpx wx data is forecasted for the future unless you change the time during planning.

 

Now every time you request wind data a request is sent to asn and the wx file is updated with new data. So as you can see there is no need to export a wx file from pfpx because that data is static and it will just get over written with new data from asn when you make a request.

 

Before the sp the wx was locked and you couldn't update it with fresh data. This was one of the features users requested to unlock the file

This is how I do it as well. Easiest way to do it in my oppinon.

I would like to know from you if you get an updated ATIS on your destination as your flight progresses? Also is the clouds/weather in general changing every time you request new wind data? People are having issues doing as you descibed above with the destination ATIS never updating and weather changing all around the aircraft when you request new wind data. Damian and team from HiFi are actively trying to solve the issue.
