Chris, just to clarity, the FDE (Flight Dynamics Envelope) includes the aircraft.cfg and the .air file.

If the ADV installation includes it's own .air file, rather than aliasing the csx732.air file from the main CS_B737-200 folder, then the ADV aircraft.cfg probably says something other than

[fltsim.1]
title= . . .
sim=csx732
model=
panel=
sound=
texture=
. . .
. . .

If that's the case then it's only applying the modified aircraft.cfg values for drag and thrust without applying the modified csx732.air values, which will result in being very underpowered.

I don't have the ADV expansion, just the original 200, so I can't do any editing with the ADV.
How does the ADV perform without any mod?

If there is an .air file specific to the ADV then more than likely it contains different values for control surfaces, flight dynamics and possibly thrust. There's a possibility the results might not be very good combining the original 200 .air with the ADV .cfg.

Thanks for update 1.4

Is "ThrustSpecificFuelConsumption" commented out on purpose in the readme or it's a typo?

Paul,
Yes the V-One gauge needs the Opt EPR offset changed.

Did a test flight and came up with -0.123 which will get the EPR real close.

1. Edit the oppropriate v-one.xml file (right mouse click on filename, then choose 'Edit'. Do not choose 'Open').
2. In section 'Initial Vars' towards the bottom of the file, change the following:
     FROM: 0.0 (>L:OptEprOffset,number )
     TO: -0.123 (>L:OptEprOffset,number )
3. Save your changes
_________________________________

I edit V-one.xml file, but I cannot find "Initial Vars" section.
I am sure it is there, I need help

Thanks
Sanal

Perhaps it's best to pick a unique expression like [color=#0000ff][i]OptEprOffset,number[/i][/color] then open the file in notepad and use Ctrl-F to find it within the code. This should lead you the way.  :)

Not sure why your inquiry is in this thread but...yes CoolP is correct.
Which aircraft are you trying to change? -200 or -200ADV?
It is imperative that you know which you're trying to change.
Below is the 'Element Name' I was referring to:

[i][b]      <Element Name="Initial Vars">
     <Element><Select><Value>
     (L:Init_Vals,bool) 0 ==
           if{
                 (A:FUEL TOTAL QUANTITY WEIGHT, pound) (&gt;L:Fuel_Total_Initial, pound)
                 1 (&gt;L:Init_Vals,bool)
                 3.0 (&gt;L:CgOffset,number)
                 0.0 (&gt;L:OptEprOffset,number )
                 0 (&gt;L:OptAltOffset,number)
           }

           (A:FUEL TOTAL QUANTITY WEIGHT, pound) (&gt;L:Fuel_Total_Current, pound)
           (L:Fuel_Total_Initial, pound) (L:Fuel_Total_Current, pound) - (&gt;L:Fuel_Total_Consume, pound)

           </Value></Select></Element>
     </Element>[/b][/i]

You should always exercise caution when making changes of this kind...always make a back-up copy.

Did more test flights and the only thing I found unsatisfactory was a bit too much gear drag. Lowered this by 8% to get proper thrust / pitch on approach.

Changes to .air file only. Aircraft.cfg values remain the same as previous update.
