MOXY: Carbon Monoxide Warnings, Straight Through Your Headset

Carbon monoxide has no colour, no smell and no taste. MOXY is a small in-line detector that sits between your headset and the aircraft intercom — and the moment it senses CO, it tells you, out loud, before you’d ever notice something was wrong.
Why every cockpit needs one
Carbon monoxide is one of the few hazards a pilot can’t pre-flight check for.
- It’s colourless, odourless and tasteless — by the time you’d notice anything, your judgement and reaction time may already be affected.
- It usually reaches the cabin through a cracked exhaust shroud or heater duct, most often when cabin heat is in heavy use over winter.
- Early symptoms — headache, drowsiness, slowed thinking — feel a lot like ordinary tiredness, which is exactly what makes it so easy to miss.
- A detector only helps if you actually notice it’s warning you. Moxy is built to be heard, not watched.
How Moxy works
Connect
MOXY sits in-line between your headset and the aircraft’s intercom socket — no separate panel-mount or wiring.
Monitor
It keeps watch on the air around you for the whole flight. No screen to check, no light to remember to glance at.
Alert
If CO is detected, MOXY speaks up immediately through your headset — clearly, over the engine and radio noise.
