Garmin GCO 14
Garmin has unveiled the GCO 14, its first carbon monoxide detector for aircraft. This remote-mount sensor integrates with select Garmin avionics, providing continuous CO monitoring and alerts for potential hazards. The system enhances situational awareness by offering real-time tracking of CO levels, along with visual and aural alerts when levels reach potentially dangerous thresholds.
The GCO 14 works with GTN Xi navigators, GI 275 flight instruments, and TXi flight displays. Pilots can monitor CO levels via dedicated pages or user data fields. In the event of hazardous CO levels, visual alerts display a “CO Level” or “CO” message on the screen, while an aural alert announces “Carbon Monoxide” when connected to an audio panel. Additionally, pilots can set custom advisory thresholds for CO alerts.

Carbon monoxide, an invisible and potentially harmful gas, often enters the cockpit through leaks in the exhaust or cabin heating systems. The GCO 14 continuously detects CO and provides timely alerts to protect pilots and passengers. By tracking CO trends over time, the system allows pilots to monitor exposure. When used with a GDL 60 datalink, flight logs, including CO data, can be automatically uploaded to a flyGarmin account for analysis.
The compact GCO 14 module is easy to install behind the aircraft’s panel and connects to compatible avionics using an included wiring harness. Certified under FAA TSO-C48A for use in certified aircraft, the sensor offers a lifespan of up to 10 years and can be replaced through a 4-pin connector.
Expected to be available in Q2 2025, the GCO 14 will be offered through Garmin-authorized dealers at a list price of 549.
