Change fuel level

[wawax]

Hello!

I try to change fuel level in one of tanks. It's quite easy, thanks to you Pete, in FSUIPC - change some offsets and that's it. Unfortunately I have to do it in XML gauge. I created APU for VasFMC A320 panel and I'd like it to burn some fuel.

 

I managed to get actual fuel level, change it, but I can't write it. I look for K:Variable, which is appropriate to write new fuel level. I know, it is called FUEL TANK LEFT MAIN LEVEL, and it is writable (as shown on ESP website, as well as in offset description in FSUIPC for programmers). But this is A:Variable.

 

Do you know the name of K:Variable which is responsible for writing fuel level? I found only fuel selectors on list of events. Or maybe I should try to write it some other way?

Sorry, you have me confused. I do not know anything about "K" or "A" variables. FSUIPC only has access to the regular values (via SimConnect in FSX, directly in FS9 -- you don''t even say what FS you are talking about ), and L:Vars, which are local panel variables which are exposed to other parts of the system.

Sorry, I have written too briefly. I use FS2004. Flight Simulator has different types of variables used in gauges. The best known are L:Vars (public variables set in gauges) and G:Vars (those stay only inside one gauge). A: E: and P:Vars are those, you can get from FS using offsets (the list is here: http://msdn.microsoft.com/en-us/library/cc526981.aspx). In gauges, they have own names, which can be used. The last type are K:Vars, which are nothing else than controls shown in FSUIPC documentation (http://msdn.microsoft.com/en-us/library/cc526980.aspx, and in FSUIPC file: List of FS2004 controls.pdf).

 

One can read A, E and P variables, but changing them is possible only via K (events). It is easier in FSUIPC, because one may change offset directly. This way it isn't possible in XML gauge (as I know, but I hope to be wrong).

 

Now I look for control (K:Var), which will allow me to change fuel level in tanks. In list of FS2004 control I found ADD_FUEL_QUANTITY, but as written in ESP, this only adds fuel. I look for something like REMOVE_FUEL_QUANTITY.

So, "K" means "KEY EVENT", as all of the controls have full names in the form KEY_XXXXX.

 

One can read A, E and P variables, but changing them is possible only via K (events). It is easier in FSUIPC, because one may change offset directly. This way it isn't possible in XML gauge (as I know, but I hope to be wrong). Now I look for control (K:Var), which will allow me to change fuel level in tanks. In list of FS2004 control I found ADD_FUEL_QUANTITY, but as written in ESP, this only adds fuel. I look for something like REMOVE_FUEL_QUANTITY.

 

Sorry, but the list of controls I publish is the complete list from FS itself.

 

In FSX there is  "FUEL DUMP TOGGLE", number 66651. I suppose you could try that number just in case, but it seems unlikely to be in FS9 as it isn't in the tables.

Thanks. That's pity.

As I know, there are some gauges written in C, which are able to dump fuel. If that gauge could communicate via L:Var with XML gauge, I could send command to decrease fuel in certain tank. I must see whether such gauge exists. Unfortunately, I don't know C, so I'm unable to write one.

You could have an L:Var which can be seen in FSUIPC, then have a Lua plug-in which reads that L:Var and write to the fuel offsets. Of course this needs a Registered install of FSUIPC too.

Thanks. That's other solution. Creating Lua will be easier for me than writing in C.
