SPAD.neXt enables you to take your experience to the next level, making the devices behave "As-Real-As-It-Gets".
Using the virtual Power functionallity you can turn the devices on/off based on pre-conditions.
You can e.g. turn a device off if the master battery is turned off. And off really means off. Nothing will be displayed , no button/switch will work. Just like in a real plane.
Devices that support this feature will have a slider button next to them, where you can turn the virtual power on or off manually as well.
Of course, you can turn this feature off in the device settings, if you don't need it.
