DA40NG - CO detector needed?

Hi all,

do we need a CO detector in a DA40NG? I can’t find any information if an air heat exchanger is installed or if heating works with a liquid based heat exchanger like in a car?

Thanks
Tobi

It's a car style water to air heater so there is less risk of CO in the cabin. But it's still an internal combustion engine generating CO. I always used one. The Lightspeed Delta Zulu has one built in, or you can buy a small one like this:

As russ said...

I have a Delta Zulu in my plane. I've checked CO from time to time. With heat off in my DA40-180 it's always at zero. But I recently had occasion to check with the heat on and it showed 2-3 ppm. This is well below the normal danger level. But it's not zero, either.

BTW, the Maintenance Manuals for Diamond models contains all sorts of information that offers lots of insights into how the planes are constructed and operate. This stuff is useful to know even if you never intend to take to wrenching yourself.

My XLS has the integrated CO detector, but during winter I also fly with a backup - works excellent.

I'm not sure either, but it has something to do with DAN's "embedded media plugin" trying to provide a clickable preview instead of a raw URL for amazon.com links. I'll investiage a bit. Meanwhile, I've tried to make your original post clickable (without the preview image).

Edit: it seems that Amazon unfortunately no longer supports the "Text+Image" embedded link feature that the plugin was using, so I've disabled it, allowing Amazon links to appear as simple URLs again.

Thank you for the recommendations, guys!
Will buy a small detector when I‘m in the US, in Europe there are only quite big detectors available

Can this device handle >28V on many of our accessory/lighter plug outlets? Is a 40NG regulated to 12V?
