To solve ILS power off problem, one option is to downgrade to the version before the bug was introduced.
You can do that using the following instructions:
Start
Type CMD
Open Command Prompt.
Type: CD C:\Program Files\Eagle Dynamics\DCS World\Bin\
Type: DCS_updater.exe update 1.2.10.32582
Once ED fixes the bug then the next time you run the updater it will update to the latest version
