Wrong, when your instruments are destroyed, you are no longer able to recover warnings such as incoming missiles.

I didn't talk about missile warnings, but the instrument systems like the indicators and gauges. Having only missile warnings disabled when you've taken a direct hit to your helicopter's instruments is very unrealistic.

Not entirely, but there's only so much BIS can do in terms of damage models for such a simplified version. However, gauges... That's another story, maybe. I'll up vote to help the cause because I would like to see advancements in certain areas.

I suppose it depends on the damage that is done to the systems. Thanks for your support.
