Once more : Today's best FSX B737 compatible with PM ?

[oal331]

I have made the same question 1 year ago, but i never find enought information and time for R&D to test POS737, so i still flying PMDG's 737 for Fs9 with FSX.

One of the major problems i noticed, when i moved from Fs9 to FSX in my cockpit, is that i have to fly always with open the Fuel Crossfeed valve, otherwise i have inbalance. I kept the same settings and PmSystem's setup and offsets, i just made a copy from Fs9's PMDG aircrafts and pasted them to FSX, with no changes. Do you know, why this problem appears? Does PMDG's files are incompatilbe with FSX?

Also, I was wondering if there is a "fresh", new solution, to combine PM with FSX. Other solutions?

Thanks

I use the same aircraft, in FSX, with PM. Mine become imbalanced only because of APU usage, After take off, when things settle down, I use the crossfeed with the left fuel pumps off to rebalance, then put the pumps back on and crossfeed off. In other words just do the balancing when needed and when I have time.

If you use the full PM suites you are surely only using the Model, CFG and Air files from PMDG? none of the gauges are relevant as PM performs the services they would provide. There's nothing left in the Air file, CFG files or Model which would cause asymmetric fuel usage.

I certainly don't see the minor imbalance from using the APU to be a "problem", only "realistic". And in any case I think all of my APU fuel usage comes from a Lua plug-in tweak I added. ;-)

Hello Peter,

of course i use only PMDG's model, cfg and air files, nothing else, but my fuel problem is there also with APU off. Is there a small change i have to make in aircraft.cfg about fuel tanks, something like any fuel value to 2 or 1 ?
Does anyone remember something similar?

Thanks a lot for your reply Peter :-)

I'm not surprised APU makes no difference, because it looks like it is only my little Lua plug-in I added is doing the fuel reduction for APU. I don't think PM does it by default.

But without that, or without using the APU and starting with ground power instead. I get no fuel imbalances at all. They are unrealistically identical! (Both engines are obviously operating perfectly! ;-) ).

I am wondering if your problem is simply that all the fuel pumps are not on. Obviously if you pump more from one side than the other you will get an imbalance.


Is there a small change i have to make in aircraft.cfg about fuel tanks, something like any fuel value to 2 or 1 ? If you email me at petedowson@btconnect.com I will send my PMDG 737-700 CFG file. You can check that. I'll also send the AIR file because I think Thomas Richter patched that for me for something to do with more realism. Don't remember what now, it was so long ago -- certainly nothing's ever been done that I know of which would make one engine use more fuel than the other.

I can't send it before tomorrow (Wednesday) as the system with it on is down at present and I don't intend to work on it till the morning.

Hi Peter,
is ok if I get the same CFG / AIR files?
Thank you
