I have a good one for you! Because I am in the middle of a flight, I opened my default C172 saved flight to see if the Alternator is on (I really don't think it is) and what I found at the bottom of the file surprised me. Here is some what I found:

[CaptainSim]
WiperPos=0
iSndPl=0
SetFuelTanks=1
FuelSelTank1=10
FuelSelTank2=10
FuelSelTank3=11
FuelSelTank4=10
L01_001_SW2=0
L01_002_SW2=0
L01_003_GL3=2
L01_005_SW2=0
L02_001_BUT=0
L02_002_BUT=0
L02_003_BUT=0
L02_004_BUT=0
L02_005_BUT=0
L02_006_BUT=0
L02_007_BUT=0
L02_008_BUT=0
L02_009_GL3=0
L02_010_LT=0

It goes on for quite a few pages! I have no idea how that got in there. :-? I know never put it in there myself. But that could make a difference.

So what I will do is backup the file, remove the [CaptainSim] information, save it and try a flight using the 727 with the fixed up C172.FLT and let you know how that goes.

EDIT [timestamp=1298131343]: I loaded my default C172 Flight and the Alternator is definitely OFF. I had made the changes to it, as mentioned above, and took the 727 up for a flight. I never lost the Avionics power nor radio communications. The only thing different, was the Pilot and F/O windows opened when I first loaded the 727.
