I just put in manual zero fuel weight into topcat.  Its so much easier and then input into the FMC of the NG the ZFW.  No need to worry about passenger weight etc.  

But the post is very informative but as Tabs said its just weight in the plane and it all equals the same.

Yes, that's an on obvious option and I do that currently with the fuel-load (total only) in the FMC. But if you would like to enter the number of passengers per section 8/8 and 119/128 for example, it is the 'Adult' weight of 175 lbs that makes that happen as calculated in both TopCat and PFPX.

Will the weight calculations in pounds convert to kilograms if KGS is selected as the unit of weight? Or does it need a complete set converted into kilograms

Honestly I don't know.  I personally always use lbs (typical American, I know. )  LOL...  I also set all my livery.ini files for each 737NGX variant to lbs as well.  You might repeat the above effort and launch each of the 737 mixed and single class variants, for each model (-600, 700, 800, and 900).  and note the kgs for each, noting the important weights (DOW, max fuel, MTOW, max ZFW, etc).

 

Then create a set of TopCat config files using kgs and the set PFPX aircraft to the same weights.  Basically repeat what I did above using kgs.

 

You might also record the proper TopCat config files with kgs here in this thread, for others to use as well.

Hi Al, ive tried pasting your values into one of the existing topcat configs with a view to saving them with thename you have given them.

But the text just goes into one lrge block instead of line by line. When I save as your filename and start Topcat its not listed in the configs that I can select.

What have I done wrong?

Hi Al - where did you get a TOPCAT .acft profile for the NGX 900?

 

Thanks for the great tutorial!

As for the TopCat profile to the two preceding questions, when creating a TopCat Aircraft, you first have to select The Aircraft Setup 'Type' to Boeing 737-700 for either B736 or the B737 Configs, or the B737-800, then you'll see either the PMDG 738 or B739 configs we created above.  TopCat only came with two aircraft type PMDG B737 or PMDG B738 aircraft profiles, one of which has to be select before chosing the configs type.

 

As for the configs file code boxes above  not paisting correctly, I'll have to repost those now as I can't edit the original post - it was a result of the dumb code-boxes and selecting "line 1" which put line-number in front of each of the rows.

 

TopCatAircraftTypeampConfig_zpse79a71a6.

 

Also, PLEASE NOTE - I forgot to mention one important field/box above while creating each of the PMDG aircraft profiles in the PFPX Aircraft Database.  Christian explains the box specifically, that uses the TopCat aircraft performance profile - you can read his description of the feature in the PFPX support forum here:

 

http://forum.aerosoft.com/index.php?/topic/72225-topcat-integration/#entry516623

 

You can actually see in my PFPX Aicraft Editor window above in my OP, in the Takeoff and Landing Performance section, I have the TopCat Performance Module set to the PMDG B737-700 CFM56-7B22 module, selected using the associated 'Edit' button.  Chose the B737 for both the B736 and B737 aircraft, and chose the B738 module for your B738 and B739 aircraft.  Not much else we can chose until realistic TopCat aircraft performance profiles are created specifically for the PMDG 736 and 739 variant aircraft.

OK, instead of manually reproducing the code-boxes above, let's see how much trouble I can get in with the mods.  I've attached the PMDG TopCat profiles (text files) to this post.  If all goes well and you can download the text files, and save them to your ..\TopCat\Configuration directory.  Then, continue creating the TopCat and PFPX aircraft as described in my OP above.

Sorry, I have to ask this question...

In the USA, per Federal Air Regulations, the standard weights for adults is 190lbs for Apr 1-Oct 31 and 195lbs for Nov 1-Mar 31.  Children weights are 85lbs and 87lbs respectively.  Can we use these weights as long as we adjust the max payload and divide by 190 (or 195)? ...or is there something here I'm missing?

 

 

I just put in manual zero fuel weight into topcat.  Its so much easier and then input into the FMC of the NG the ZFW.  No need to worry about passenger weight etc.  

But the post is very informative but as Tabs said its just weight in the plane and it all equals the same.

I'm also inclined to agree with this...however, we do need the profiles in TopCat for the variants, so this is great information nonetheless. 

Many thanks!

David,

I'm in no position to provide conjecture to your seemingly knowledgeable weight regulations.  But, what I have provided, 175 lbs per person, is what truly works with the way the PMDG 737NGX aircraft models were coded.  If you want the number of seats filled and the weight to match across all three programs, you have to set it accordingly.

Sounds like 175lbs is the number....

 

Thanks!

Al, I cannot thank you enough for sharing your work.  As a longtime TOPCAT and NGX user, I was always wishing for a proper NGX specific profile, and now we have it!  We were previously limited to the PMDG profile for the FS2004 addon. 

 

Not a knock against you, but I just wish there was a way for the payload screen in the NGX FMC to match 100% what we see in the payload manager in TOPCAT, in terms of the passenger and cargo distribution.  The zero fuel weight is correct of course, but there will be a big difference in CGs, and I would think, trim settings between the two.  I know Tabs had said weight is the important figure, but what about cg?  See screenshots below:

I have, and will continue to disregard the CG setting recommendation in TOPCAT.  We have always been instructed not to trust TOPCAT in this regard, just use the FMC as it is really the best app for this purpose.  But I just wish the FMC would match the passenger/cargo numbers of TOPCAT, perhaps it's my OCD and also a FSX limitation, or custom coding by PMDG that TOPCAT or any external load program is not equipped to handle.

 

Any thoughts?
