Fuel Flow Indications

With the latest version fuel flow indications are way too high. Otherwise this is a great aircraft.

Which sim version are you running? The fuel flow calculations for FSX and P3D are different, so adjusted logic is used for each.

Check your panel.cfg files to make certain that the correct logic gauge is configured:

Code: Select all

gauge01=B737_XML!B737_Logic_P3D,  0,0,1,1

This version of the gauge has the correct fuel flow calculations:

Code: Select all

    (A:ENG FUEL FLOW PPH:1, pph) 100 / (>L:ENG FUEL FLOW PPH:1,enum)
    (A:ENG FUEL FLOW PPH:2, pph) 100 / (>L:ENG FUEL FLOW PPH:2,enum)

Thank you for the reply.

I’m unable to locate the two fuel flow lines of code.

The line.... guage01=B737...... is the same.

Fuel flow shows in for me 4000#/hour per engine for example.

I’m unable to locate the two fuel flow lines of code.

Those lines of code are in the ..\gauges folder in the B737_XML.cab file. You can unzip the .cab file and look for the B737_Logic_P3D.xml file. Open that file with Notepad or Notepad++ and search for those two lines.

Thanks for your suggestions. I can find a section - turbine engine data - but not what you've suggested I look for. I am not the sharpest knife in the drawer when it comes to this stuff but i can find the gauges folder in other add-ons but not here. Thanks for your time.

Here is the gauge in my P3Dv4.3 sim folder:

Greetings,
I found it. Thanks for your patience. It is appreciated.
Here is what I have:

(A:ENG FUEL FLOW PPH:1, pph) 0.798 * 10 / (>L:ENG FUEL FLOW PPH:1,enum)
(A:ENG FUEL FLOW PPH:2, pph) 0.798 * 10 / (>L:ENG FUEL FLOW PPH:2,enum)

As you can see it is different.
My sim: (P3dV4.3)

I have no idea why that may have happened to your installation, but the fix is to simply replace those entries with the P3D version:

Code: Select all

    (A:ENG FUEL FLOW PPH:1, pph) 100 / (>L:ENG FUEL FLOW PPH:1,enum)
    (A:ENG FUEL FLOW PPH:2, pph) 100 / (>L:ENG FUEL FLOW PPH:2,enum)

Greetings.

I changed the lines as instructed. No change.

I uninstalled the B737 then re-downloaded and reinstalled. No change. Idle still 3800 pounds per hour per engine.

Is there any chance you might send me another download link to whatever version is the most current? What I just downloaded and installed was 180823.

Also I just emailed you a pic of the engine gauges at idle.

Something is definitely screwy with your installation.

Please try this set of files. The B737_XML.CAB file goes in the ..\gauges folder of P3D. The two panel.xxx files go in the SimObjects\Airplanes\MV Boeing 737-200 folder :

I'm not sure if this issue was resolved for the original OP?

I'm having the same issue...haven't flown the B732 in a long time.

Downloaded the most recent installation file from this forum (4.180823_wx). The download and installation were both done with A/V off. Installed into P3D v4.5 with HF2.

After installation, I'm having the same issue. In C&D, the fuel flow is zero. After start-up, the minimum fuel flow is 5800 pph (same as the OP's attached photo).

I looked at both my panel cfg file and the gauges file to ensure I had the correct P3D installation...both were as required according to Bill's previous post.

Although I didn't find an issue with my Gauge CAB file, I did elect to download/install the "NewFiles" that Bill posted here...those files gave me a CTD. Went back to my original files. The B732 is now loading, but, still have this fuel flow issue.

I went back to the Milviz store to ensure this product is tested for P3D v4.5.

Any ideas on what i can try?

Thanks in advance.

I haven't flown it in quite a while either due to this fuel flow issue. Takes immersion and realism away for me so I haven't come back to it. Really too bad as otherwise it's a nice aircraft.......
