To all,
Below is a procedure I've developed for successful use of the fine
CIVA system with the Captain Sim B727.  

Link to the textfile for download >>

  CS B727 Captain (for FSX) with Delco Carousel INS installed,  Startup Procedure >

Purpose >
Eliminate the CDU constant (yellow) battery light and subsequent CIVA system
shutdown,  to enable normal CIVA INS operation in the Captain Sim B727

Developed using the following environment  >
Win7-64, FSX Acceleration, FSUIPC (latest version), Captain Sim B727-100, CIVA
Ver 1.51 Dual Redundant setup, (readily available CS721
panel.cfg file{slightly modified} with additional texture files).

 Those of you who have learned the Delco Carousel Inertial Navigation System (CIVA )
will likely find this writing somewhat "long-winded".  Those of you who haven't had much
exposure to the Delco Carousel CIVA will likely have some questions.  

The checklist >
1.  Delete ..Flight Simulator X\CIVA\*.isd file( just to be safe) prior to every flight >> a good
    and harmless safety measure.  NOTE: To be effective, this step must be accomplished
    before loading the B727 in the sim.
2.  Start FSX
3.  Load Default Flight (I use Cessna 172)
    NOTE: To be safe, use Keys and Keyboard combinations only (not the mouse) to
    accomplish the following :
     a. Shutdown engine (Ctrl + Shf + F1 > or your custom key assignments )
         NOTE: If you leave the red Mixture Knob in the (pulled) out position,  then when
         the B727 is loaded, the Engine Start Levers on the Throttle Pedestal will be in
         the correct (closed / lowered) position.
     b. Switch off battery and alternator (Shf + M)   IMPORTANT: Leave the Cessna's
         avionics switch ON.
     c. Other Cessna switches OFF except Magneto switch (optional) and Avionics
         switch (Important)
4.  Select / load a CS B727 that has CIVA properly installed
5.  Move the B727 to world location of choice
6.  Set parking brake
7.  Set payload, fuel, time, date, etc.
8.  Turn on INS self power by setting all MSU mode switches to "STBY"  (Leave the
     APU and aircraft battery switch OFF)
9.  Perform normal CIVA preflight checks and alignment >>  set present position,
    waypoint entrys, distance checks, etc (ADEU works too, for those who use *.AWC
    files to enter waypoints)
10. While INS is aligning > preset the cockpit gauges and switches (that can be preset
     with aircraft power OFF) as necessary for the flight, and make / ensure the following
     settings on Engineer's Panel:
     a. Electrical system battery switch = OFF
     b. Essential Power switch = Gen 2
     c. Set / Ensure all 9 main generator toggle switches centered and their associated
         indicator lights off
11.When green ready lights appear on the MSUs (APIs = 5 or less on CDU), set their
    mode switches to"NAV".   WARNING: Do not forget this step >> if this step is not
    accomplished before the aircraft pushes back / taxis then the INS alignment will
    invalidated,  and the aircraft will need to be stopped (parking brake set) and the
    alignment restarted ~:)
12.Toggle the B727 electrical system battery switch (upper engineer's panel)  2 (TWO)
    times (Shf + M)
13.Start the APU > IMPORTANT: DO NOT toggle the APU Generator switch. Use the
    APU AIR ONLY (for Engine start).
    Info: The battery will power all radios and other necessary aircraft systems during
    engine start (unrealistic > but it gets better ~)  
14.Start engines (my order of start is 2, 3, 1)
15.Now, "it gets better" >> VERY IMPORTANT: Do not touch (or breath on) the 9 main
    generator toggle switches on the Engineer's Panel (and hope that all 9 indicator
    lights remain extinguished).  Aircraft systems are now powered by the #2 Engine
    Generator (or FM ~:)
16.Shut down the APU
17.After Pushback,  when brakes are released and taxi power is applied, if you don't
   see the dreaded CDU yellow battery caution light, then all should be well.

The autopilot worked well for me in Heading mode, however on the first flight (with "ALT
HOLD" not engaged) the aircraft elevator trim wheel (on throttle quadrant) wanted to
remain in center (neutral) position and the nice Pitch feature of the yoke was locked (inop),
which made the climb to cruising altitude more interesting than desired.  If you experience
this, then I recommend temporarily toggle off the INS and disengage the auto pilot (just for
the altitude changes).  When at desired altitude switch the AP and INS back on.
As an alternative to the above, you can try using the Turn and Pitch Controller knob on the
Auto Pilot panel for pitch adjustments.  This has worked well for me lately.
AP "ALT HOLD" mode works fine, and INS connects to the AP with no issues when
AP "HEADING SEL" mode is engaged.
Also would like to mention that on my last two flights INS Dual DME Updating fiunctioned
perfectly.  I have read several comments stating that this feature was not working,  so this
was a very pleasant surprise.

I successfully tested this procedure five times before I considered sharing it.
Disclaimer: I can't guarantee that this will work as well for everyone as it did here. As most
of you may know, the very fine "CS B727 Captain" software and very fine Simufly CIVA INS
were never actually design to work together,  and therefore I found it necessary to "adjust"
some of the CS B727 operating procedures (a few of them obvious as noted above) to coax
them to get along together.  If it seems that I missed a detail or two (or three) well it's certainly
possible.  It's early,  so please consider this a "work in progress".  I'm always open to tips
and suggestions for improvement and of course questions.  I'll update this "essay" as the
adventure continues, if warranted.
Best to all,
Ken Boardman
