[FS9 Offsets]

On FS9, offset 0AF0 tells you. Simconnect doesn't supply this data.

Oh, I missed that one :)

Thank you!

Another three things:

1. I see the offsets 060C and 060E for gear type are not used by FS9.

Is there any way to get the gear type? I didn't find anything in aircraft.cfg also.

2. I also noticed the result of offset 0784 (carb heat available) is true for the planes like King Air 350, B737, 747 and others.

3. Does FS9 use seatbelts sign at all?

[problem with getting the right RPM value for some aircrafts!]

I also remember putting the request in to the FS team for the Ratio to be provided, via SimConnect.

But actually SimConnect gives direct access to prop RPM value.

Anyway, back to FS2004...

I updated FSUIPC to ver. 3.871

I found the formula I provided before:

0898 * 08C8 / 65536 / gear_reduction_ratio

is true for some planes only. It's ok for King Air 350, C172, Beechcraft B58 but it's not for DC3 or Cessna Grand Caravan.

DC3 has 1.778 gear reduction ratio in aircraft.cfg file but I obtain true prop RPM from 0898 * 08C8 / 65536 / 1.0 (not 1.778)

and Cessna GC gives completly wrong results...

So I'm stuck again. I have no idea how to get this value :(

[problem with getting the right RPM value for some aircrafts!]

Sorry Pete. I will try to be more precise.

It's FSUIPC 3.85 for FS2004 downloaded one week ago.

The only place in doc I found is:

0898

Engine 1 Jet N1 as 0 – 16384 (100%), or Prop RPM (derive RPM by multiplying this value by the RPM Scaler (see 08C8) and dividing by 65536).

And I discovered for every prop plane it must be 0898 * 08C8 / 65536 / gear_reduction_ratio which could be sometimes just 1.0 as for C172.

I could read the CFG file but how should I know the exact path of such file?

[problem with getting the right RPM value for some aircrafts!]

I've just found this post searching net for solutions but still had some problems.

Now I figured it out it should be 0898 x 08C8 / 65536 / gear_reduction_ratio.

I could swear I tried only 0898 / gear_reduction_ratio and I got right value but I had to be wrong.

So formula is clear now but do I still need to read CFG file for gear_reduction_ratio? Isn't there any direct access to prop RPM value through FSUIPC?

I use latest version of it ofcourse.

[problem with getting the right RPM value for some aircrafts!]

Well I still can't get prop RPM value using both methods.

Airplane: FS9 default King Air 350

Gauge prop RPM ~1700

Method 1, as stated in doc:

0898 x 08C8 / 65536 = 36215 x 54144 / 65536 = ~29919

Method 2, 0898 / gear reduction from CFG file:

36215 / 17.6 = ~2057

Am I doing something wrong?

First, the offsets 0BE0 and 0BE4 are for actual flaps position not the handle.

But I found and used 0BDC offset to derive handle position so one problem solved :)

Now the angles. The values in CFG file are true angles not label values.

e.g. C172

flaps-position.0 = 0

flaps-position.1 = 12.7

flaps-position.2 = 25.3

flaps-position.3 = 38

and on the label in the cockpit there is 0, 10, 20, FULL. So I think I 'm not able to get label values that's why I request at least actual true angle from Simconnect but it seems for FS9 I will have to read CFG to obtain max flaps angle to do the calculations.

*************

Pete, do you know how to check if the plane has adjustable prop?

I use min and max prop beta angle in Simconnect. If they are different then it's adjustable but I found the offset only for actual beta angle (2418).

[FS9 Offsets]

Apart from using FSInterrogate to check things, why not search the document listing all the offsets? I found that one in two minutes just searching for "flap". The full documentation is the document. Don't rely on what is written in FSInterrogate FSI files and they are difficult to maintain and not done very thoroughly.

Ofcourse I use documentation as my primary source. I had to ommited that one ;)

Why do you need the true angle?

This is one of many variables displayed in my application in addition to flaps positions.

I would like to display flaps handle position as flaps angle displayed on the label next to the handle but I can't get it from FS so at least I display true flaps angle.

[FS9 Offsets]

Thanks Pete!

FSIterrogate turned out useful.

Now another problem with the offsets. In Simconnect some values are given directly and here I need to calculate some things.

I need 3 things:

1. maximum number of flaps handle positions

2. actual handle position

3. actual flaps angle

As i know I will need maximum number of flaps handle positions so I can derive actual handle position from 0BDC but i can't find the offset for it.

And it seems I will need max flaps angle to calculate actual angle.

Do I need to read aircraft.cfg some way for that?

[FS9 Offsets]

No, you didn't understand me. I don't want to map it twice ;)

I found the 3D00 offset but documentation says "3D00 - Name of the current aircraft (from the ―title parameter in the AIRCRAFT.CFG file). Valid for FS2K only."

And I connect to FS2004 not FS2000. Is it an error in doc?

[FS9 Offsets]

Very colourful! ;-)

Pete

I hope it is a compliment ;)

Btw, I can't find another offset for user aircraft title...

And I need it to know when the user change his aircraft or maybe there is another way to check it?

[FS9 Offsets]

I'm rewriting my application to work with FS2004 (version for FSX was made using Simconnect) and I can't find offsets for total fuel capacity and actual fuel quantity.

Do I need to sum all the tanks capacities and fuel quantities?

Btw, my software: :)
