I don't really know how to describe the problem

Hi,

I've a problem with PMDG and FSX since a few days, and I don't know what's really wrong here. I'll attach a couple of pictures to ilustrate what I'm saying:

As you can see, the VS is really high, and the TAS/GS/Mach number really low for that altitude.

 

I had the same problem on others locations around the world (and obviously with other weathers scenarios)

My FSUIPC it's the 4.937 registered, with WX optiones turned off. One of that situations were with Active Sky Next SP1 and the other was without, and ISA weather.

If you need more specifications please ask. Hope you can help me.

Regards,

You have FSX set to display True airspeed instead of Indicated airspeed. The fact that your airspeed shows 320 knots, but the Mach number is only .488 (at 32000 feet) is a sure sign of this.

 

Go to the "realism" menu in FSX and click on the option to display Indicated airspeed, and it should solve your problem.

 

Also, as KriVa mentioned, in the second photo, your outside air temperature is very high for the altitude you were flying at, which could be caused by your weather program.

Hi,

 

It's IAS, and the problem started when I've installed ASN SP1, but the second picture is without Active Sky, so...and I've made the a first leg flight of this GIA route yesterday and everything was fine, so it's not a constant problem.

I'm a real world 777 pilot, I know the mach and IAS numbers are wrong for that altitude, it's like a change in air density, but I don't know how to fix it. You can also check GS... it's like a low altitude flight, at F320 :( And I had 3 hours of fuel in tanks, in a B777-300ER, the VS with that fuel and that ZFW (212.3 tons) most to be around 2000-2500 fpm...

Anyway, I'll check the HIFI forum for a solution. If you guys have any other idea I'll glad to read it ;)

 

Thanks

Hi, AR,

 

Certainly is weather-related -- the IAS being close to TAS would make sense if you were at a much lower altitude. So would being near the speed redline on the  PFD at that TAS.

 

You have the very latest version of FSUIPC that just came out a few days ago.  Maybe there is a new bug in it.  Try removing the FSUIPC.dll from the FSX modules folder.  If that fixes the problem, put the dll back in, move the fsuipc.ini file to another folder and allow it to rebuild.  You will lose control settings but you can put back the backed-up ini file if that is not the problem.

 

Another possibility:if you keep starting up w/ the same panel state, especially one you keep saving and reusing, maybe the panel state got corrupt.  Try starting a new flight using one of the PMDG-supplied startup panel states.

 

Another thing that might be interesting is to take the altimeter out of STD and press control-B -- see what pressure it shows.

Hi,

 

It seems to be an ASN sp1 problem, related with ASN/FSX communication. Thanks guys. It is indeed a weather related issue.

 

Cheers.

 

Hi,

I am having the same exact issue as you on my ngx, using ASN. Is there a fix for this or a fix planned? Can you let me know if you know anything?

 

Much appreciated

Hi,

 

Take a look here:

I'm flying right now with Opus WX and averything it's fine.

 

I hope HIFI can give us a solution soon

Thank you very much for the link, I appreciate that. I think I will try rolling back to ASN before SP1 as this is the only weather engine I have. Lets hope they fix this soon!
