Problems with Legacy or Modern Fuel Systems

I'm not going to criticize, but simply observe...


The Legacy system does not display more than 5 tanks in the simulation window, while there is the possibility of using up to 11 tanks in the flight_model.cfg...! Why is that?


The Modern system allows you to display the amount of fuel available in the tanks with the variables FUELSYSTEM TANK QUANTITY:index or FUELSYSTEM TANK WEIGHT:index or FUELSYSTEM TANK LEVEL:index. These variables are settable...!
In my example, I use 7 Tanks defined Tank.1, Tank.2... Tank.7. I can see the amount of fuel in (A:FUELSYSTEM TANK QUANTITY:1), (A:FUELSYSTEM TANK QUANTITY:2)..... (A:FUELSYSTEM TANK QUANTITY:7).

But when I want to modify the content of the tanks by (>A:FUELSYSTEM TANK QUANTITY:1), (>A:FUELSYSTEM TANK QUANTITY:2)..... (>A:FUELSYSTEM TANK QUANTITY:7),...

  • tank.1 is modified by the command (>A:FUELSYSTEM TANK QUANTITY:6),
  • tank.2 is modified by the command (>A:FUELSYSTEM TANK QUANTITY:7),
  • tank.3 is modified by the command (>A:FUELSYSTEM TANK QUANTITY:8)... (!!!!!!! while I use only 7 tanks...),
  • and I can't modify at all the fuel quantity for tanks 4 to 7...! So what is going on...?


Thank you for taking the time to address these issues!


Best regards,

Hello @ChrisSMS

When you say "simulation window" you mean the fuel panel?
If so, I think it was just an issue with UI not being refreshed correctly on a Save&Resync.
I no longer have the problem on the SU10 flighting build, can you check it's working as expected for you too?

Regarding the indexing system. That's something we're looking to change with SU10.
The new fuel system uses the legacy indexing system, using the position of the tank to determine the index.
We will fix this in a later flighting build and when using the latest fuel system version, you will now use the index defined in the cfg.

Regards,
Sylvain

Hi Sylvain,
Yes, I did mean the fuel system window...! I will check what happens if I increase the number of tanks in SU10: I had opted for a solution of grouping the tanks so that they are visible in the said window... I'll let you know as soon as I can do the tests.
And thanks for taking into account my request for the new fuel system...!

Greetings, and good flights!
Chris

The change on SU10 is not available with the flighting yet. It probably will with the next build (we will update the flighting build before the final SU10 release)

OK Sylvain...! But I just did a test for the number of tanks displayed with the old fuel system: it still doesn't work! If all the tanks are used, they are all displayed. But in my case, I use CENTER 1 + LEFT MAIN + RIGHT MAIN + RIGHT AUX + LEFT AUX + ETERNAL 1 + EXTERNAL 2... and my EXTERNAL 2 is not displayed!

That's right, I tested by enabling all tanks but the UI is incomplete when having some tanks only. Simvars are matching what's defined in the CFG though so I expect it's only a UI issue. I will file a bug about this.
Thank you for reporting it. :)

Regards,
Sylvain
