I observe that when I load the CS727 a KSEA to KSEA flight is automatically loaded in FSX's planner.
How can I disable this ?

Also since I use the manually added and use the double CIVA INS units I assume that disabling the CS INS (from panel.cfg) will not cause any problem, right ?

I don't think you can disable it since it is the default flight, just load the one you want to override the default one. It is that simple, no big deal.

Hi

To disable this Flight plan.Do that
1 Browse cs727base.PLN in Flight Simulator X files folder
Rename the Flight plan cs727base.PLN to cs727base.INACTIVE or BACKUP for example (you converse the file in case that I need to come back)
2 Do a copy of 727-100 Cold-n-Dark (KSEA).FTL
Rename the copy 727-100 Cold-n-Dark (KSEA) copy.FTL to 727-100 Cold-n-Dark (KSEA).BACKUP
3 Open FSX and load the 727-100 Cold-n-dark (KSEA) flight, an error message appear, accept.
4 Check you don`t have flight plan loaded on GPS
Save and Overwrite the flight 727-100 Cold-n-Dark (KSEA)

The default cs727base.PLN is required for the INS to initialise when it first loads into FSX/FSX-SE/P3D. There is no need to remove it, or disable it, because once you create/load another flight plan, the default flight is replaced in the INS by it. ;)

Yes but if you use CIVA INS then its useless.
Also I use ASN for weather which autoloads (ok there is option to disable it) the FSX flight plan.

Okay. I get where you are coming from. You're using the SimuFly.com CIVA INS, not the Captain Sim included CIVA INS. ;)
