WXR Display Issue

[crashbar 2]

I took the 777 out the other day after fiddling with the QW 787 for a few months.  I did a flight from KIAD to OTHH and noticed when I turned my WXR on that it appeared the weather was disappearing under the 40nm mark.  I have the plane at 37,000ft. and the radar on "automatic mode" -2 which is very standard.  When I started this flight from KIAD their were storms and the depiction was showing moisture clouds all around the plane as one would expect.  After taking off the higher my altitude the further away it pushed the moisture clouds back until I finally reached TOC. I don't ever remember the WXR doing this.  I have reinstalled and made sure everything is up to date only to get the same results.  I run FSX/Accel with Direct10X Fixer, AS2016(engine), REX SkyForce + REX 4 TD(texture).  I will say since the last time I flew the 777 I have added REX SkyForce and have already posted in their forums as well as HiFi and waiting to hear back.  Any help is much appreciated, thanks, Crash.

you  said  you posted  it  in the  rex  forum  since  you  run  sky force ,   are  you  sure  your  not  running  both  weather  engine  at the  same  time  as2016  and    sky  force  weather  engine?

[crashbar 2]

Yes.  I went through the manual at each section and turned off everything that requires the weather engine.  When I use it I load SkyForce first, double click the "Enable REX Weather Engine" option so that the status changes from "Disconnected" to "Disabled" (a known bug) and then start up AS 2016 followed by FSX.  I always load the FLP from PFPX into AS 2016 and PMDG 777 also.

Also here is something else that will make no sense, this only happens in the 777 radar.  The QW 787 radar with WXR enabled at 41,000 ft was showing any clouds with moisture all within 40 nm.(I believe it has only a 40 nm limit where as the PMDG is 80 nm).  I have not tried my PMDG 737 however.  BTW I'm not trying to compare products here and say one is better than the other I'm just trying to give all the information I can that may point to something.

Try deleting the FSUIPC.ini and see if this fix it. We had similar reports and the FSUIPC.ini was the reason.

I did update my FSUIPC around the same time I installed REX SF, and their is now even a newer version so I will try that and report, thanks.

What is the draw distance in your weather program?

[crashbar 2]

I updated my FSUIPC and deleted the INI twice to make sure, but it is still doing the same thing.

In AS 2016 I have minimum cloud draw set to 100 and maximum cloud draw set to 140.  LIke I said though when I start descending the clouds with moisture will start appearing closer and closer.  In fact, from the ground all the way to about 20,000ft. the WXR will show any moisture clouds within 40nm.  It's always when I start getting above 20-25k ft. I notice moisture clouds starting to get pushed back more and more.  Very strange.

REX contacted me back and this is what they said:

"The beam of a radar goes straight out from the dish unless you change the tilt of the dish.  So what you are seeing is likely the tops of the clouds with their water droplets.  But as you noted you descended the weather filled in.  This is because you are getting closer to the bases and more clouds".

This could be true however I have watched videos made by Frooglesim and Kyle that show them both at 30,000+ altitudes in WX-T modes at -2 with the WXR radar easily showing moisture clouds within 40 nm so I don't believe this statement is correct.

Well I did a complete FSX reinstall which took a few days.  I only installed FSX, AS 2016 and PMDG 777 and have the same results.  Guys is it just me?  Am I tripping here?  Is there anyway someone wouldn't mind when they get a chance to take the 777 out with AS 2016 and tell me at around 37,000ft. if your MFD with WXR enabled shows moisture clouds with in 40 nm.  I need to know before I have a nervous breakdown, Crash.

Of course it does... otherwise, there would have been many many others posting this as a problem.  Last time I saw active returns within 40 nm was last night in my B736 approaching Labrador.  I don't recall exactly but I did have a 777 trip with those returns recently. Could've been my last KMIA-SBGR trip.

Ya I mean a complete reinstall of the FSX, 777 and AS16 with same results.  Also my QW787 wont let me go past 40nm lol.  I'm really at a loss.

[crashbar 2]

Well after finally talking with a QW staff the radar is only capable of 40nm so good news there.  I'm starting to think this is not on my end.  Either its HiFi, PMDG, or I'm tripping here.  Like I said the 777 shows precip within 40nm the closer to the ground I am.  So if this is correct than something has changed because I always remember being able to see precip within 40nm at high altitudes before.  I don't know if HiFI has changed something or not.  Still waiting to hear back from them. 

[JRBarrett 3,070]

Have you tried increasing your down tilt angle manually? At a tilt angle of 2 degrees down, the beam will go right over the top of any lower precipitation the higher you are flying. Unless you are heading toward large cumulonimbus buildups that reach or exceed your current flight level, it would not be at all unusual to have no returns closer than 40 miles at higher flight levels.

Based on simple trigonometry, if you were flying at 35,000 feet (5.7 nm above the surface), in order for the beam to hit the ground 40 nm in front of you, the down tilt angle would have to be about 8.1 degrees. This is not “exact” because the calculation assumes the earth’s surface is perfectly flat, rather than curved.

At 1 nm altitude, the down tilt angle would only be 1.4 degrees to hit the ground at 40 nm in front of your current position. 

Of course, you are not really looking for using the radar to map the terrain, but it illustrates that the higher you fly, the more down tilt is required to see “close in” precipitation when in level flight.

[crashbar 2]

Yes when I tilt down manually to 15 I can get moisture signatures about 30nm away so this definitely moves it in closer.  However, since I have owned the 777 and all the flights I did obviously at high altitudes I don't remember seeing moisture signatures being supressed to just 40 nm in Auto mode.  In the video below you can clearly see at 37,000 ft with the WXR in Auto mode that moisture signatures have no problems being shown within 40 nm.  I cannot reproduce this.  So either 1)AS16 is not working properly  2) PMDG 777 is not working properly  3)Both are working fine and I'm tripping.  If 3 is correct than someone changed something because I never had this issue before, and after completely reinstalling FSX, AS16 and the 777 and still having the same issue.......I'm starting to think that number 3 is correct and I need to just move on.  But if something is not right, I HAVE to know lol.   Thanks, Crashbar.

I had this too but only when using custom weather and it's a long time ago.

My 2 Cents.

[crashbar 2]

Ya nothing custom here just AS16 and REX with pretty much default settings.   But thanks for the 2 cents.  I'm "broke" right now with ideas and will take anything, Crashbar.
