Help setting aircraft payload and fuel needed

[sxa1376]

Dear Pete,

I am trying to create a small utility to read my aircraft weight and fuel stations and then to write new weight and fuel.

The aircraft i am using is a standard airbus a320 of the "project airbus" team and the stations i want to manipulate are these:

 

[WEIGHT_AND_BALANCE]
//Cebu Pacific A320-214  RP-C3241 config
     
 

//Pax Zonings
station_load.0= "7605.9, 21.24, 0.000, 0.000,  CAB OA (60)" 
station_load.1= "7149.6,  -3.33, 0.000, 0.000,  CAB OB (60)"  
station_load.2= "6541.1, -26.34, 0.000, 0.000, CAB OC (59)"
-ok

//Cargo & Baggage
station_load.3= "2921.1,  22.10, 0.000, 0.000, CPT 1"   //Compartment 1 (7500lbs)
station_load.4= "3086.5, -11.99, 0.000, 0.000,  CPT 3"   //Compartment 3 (5349lbs)
station_load.5= "1190.5, -22.67, 0.000, 0.000, CPT 4"   //Compartment 4 (4652lbs)
station_load.6= "171.96, -33.11, 0.000, 0.000,  CPT 5"   //Compartment 5 (3300lbs)

and

[fuel]
Center1=   4.15,   0.0, -4.00, 2179.6, 8.0
LeftMain=  3.31, -19.6,  1.40, 1829.6, 5.0   //3.45
LeftAux=  -4.80, -36.4,  2.20,  232.5, 5.0
RightMain= 3.31,  19.6,  1.40, 1829.6, 5.0   //3.45
RightAux= -4.80,  36.4,  2.20,  232.5, 5.0

 

I am using C# and i need some help in order of which offsets i must use for this to work and if possible a quick sample just for one station of weight and one station of fuel.

Many thanks in advance.

George.

Sorry, I've no idea about C#, and really cannot do the programming for you. I can answer specific questions about FSUIPC and its offsets, but first you need to find them in the Offsets Status document (in your FSUIPC Documents subfolder) and read what it says about them.

Are you using Paul Henty's .NET DLL for your application? Because you should. It makes things easier for such languages. And he has his own support in a subforum above.

Dear sxa1376

We agree with Pete. We programm in VB6. However it is the same in C++.
We assume you have FSUIPC4 Offsets Status.pdf open to your hands.

Fuel
You need to change the Percentage-Level of the tanks, start with offset
&H0B74,   4 bits,    Fuel: centre tank level, % * 128 * 65536.
100% = 8'388'607 (= 128 * 65536), equals at 50% to 4'194'303 to be written into the 4 bits

Payload
It depends of your aircraft.cfg file.
Start to research on offsett &H1400. Each Station has 48 Bites.
Write the weight in lbs into &H1400 + 0 = &H1400, a double of 8 bits.
Next station:
 &H1400 + 48 bits equals to &H1400 + &H30 = &H1430.
Write the weight in lbs into &H1430 + 0 = &H1430, a double of 8 bits.
And so on until you have all stations set.

By the way you can put as much you want and make your Cessna 172  1'000'000 pounds heavy.

Dear Pete and Peter,

Thank you very much for yoyr answers, i will try the offset 1400 and i hope i make it work.

 

Best Regards

Dear Peterk54,

I tried with offset 1400 and worked fine until offset 1520. Which means that I can load only five payload stations. after that (offsets 1550 & 1580) are inoperable. Not only that but offset 1520 loads the final (seventh) station instead of the fifth.

Do you have any suggestions for what am I doing wrong?

Thank you very much in advance

Best Regards 

George

1400 to 1520 inclusive covers 7 stations: 1400, 1430, 1460, 1490, 14C0, 14F0, and 1520. How do you count only 5?

BTW FSUIPC simply handles these with SimConnect using payload station numbers, 1 - n, where n si the number of paystations supported by the currently loaded aircraft, as supplied in offset 13FC. FSUIPC does not process this data at all. What you get/set is just what FS and SimConnect provide and allow.

To sx1376

Pete is correct, you should receive 7 tanks from offset 1400 to 1520. I write exactly to these offsets: Upper Deck, Section A to E. Payload in 1550 and 1580.

A) Wrong offsets increase
1400 to 1430 ar steps of 30 (in hex) , 48 (in dec). You mixed up ?

B) Wrong definitions
Check read 4 bytes at offset 13FC. Do you get equal or more of your total PAX sections and payload ? Check your aircraft.cfg. Only one line of "max_number_of_stations=n" ?
Sample:
max_number_of_stations=9
station_name.0
...
station_name.8
station_load.0
...
station_load.8

C) No more ideas, wait your feedback !

Best regards
Peter

Thank you very much!!!  In fact I got confused indeed with the hexadecimal values. 

Works like a charm!  Thanks again!!!

Dear sxa1376

Great ! Such things happened to me as well !
Let me know if you have other questions.

Best regards
