Aithre Shield CO Detector

I never paid much attention to CO detectors until I listened to these two episodes from Max Trescott’s Aviation News Talk podcast -

Thanks everyone who posted PIREPs on the Aithre detector, based on your feedback I’m ordering one.

I am installing Aithre 3 detectors in several aircraft and a few available for a good price.
Email me if you're interested.

I just installed one of these in my plane yesterday. Per the instructions, it was just a matter of adding 3 new pins into one of the GEA 24 connectors and then doing a few simple configuration steps on the G3X.

However, when I first tested it, the unit didn't power up. When I checked my connections, I found the Ground from the Aithre going to "Lo" on the GEA 24 was not really a good ground. At Walt's suggestion, I spliced in a direct airframe ground wire in addition to the wire going to the GEA 24 Lo. Adding the direct ground solved the problem and the Aithre came to life on the second try.

I'm looking testing it in flight.

I've installed one in my RV7 and connected it to the Skyview. Installation and configuring went pretty well. It is so small, I just zip tied it in place. I am usually seeing 1 ppm in flight. I saw 3 ppm during a taxi run up once. I have the wing push rod boots installed and foam insulated the rear bulkhead stiffener openings for cold drafts reasons. I think that helps from drawing in any CO vapors. In flight I see no difference with the heater on or off. I had tested it in place with smoke and the readings increase, then decrease when I remove the smoke. That tells me it is working. I'm real happy with the Aithre Shield and feel more comfortable about flying and our health.

Anybody have any contact info for Aithre? Nothing on their website. I'm looking to find out whether the data from the apps are downloadable.

Thanks,
Greg

Thanks, Walt. I finally did find a phone number and called them, ordered both an oximeter and CO detector.

For the record, they are just about to release an app version that allows downloading the data to an excel file.

Cheers,

Sad story that happened in Australia with the loss of a DHC Beaver,

Please consider installing a modern CO detector linked to the alarms on your EFIS !


It?s been over a year since I installed the CO detector and I have enjoyed the challenge of finding all the different places the CO can enter the cabin.

My aircraft has A/C and with the external vents closed i was still getting elevated CO levels in some flight conditions ( mainly extended climb at full power ).
( Max reading of only 20ppm)

My firewall and penetrations are well sealed so my thoughts were the corrugated baggage bulk head was the obvious entry point. I sealed up the bulk head and I am still finding elevated CO during climb.

I am still looking but if it was not for my Aithre Monitor linked to my EFIS, I would never even of known !

I have been doing the same thing - looking for CO ingress leaks. Only occurs when rich of peak (makes sense) but occurs in level flight as well as descending. Firewall recently checked and any questionable spots resealed, no joy. Taped the cowl edges and NACA vents, no joy. Next step is looking at wing roots. Levels are not high (less than 20 ppm) but enough to warrant figuring this out.

I have sealed the wingroots also with no joy. I suspect it is coming from the tail portion by the low pressure in the fuse but it is hard to seal that portion off.
