Garmin introduces GCO 14 carbon monoxide detector

Garmin has launched its first carbon monoxide (CO) detector for aircraft.

The GCO 14 detector has a remote-mount sensor that can integrate with select Garmin avionics to monitor CO levels and alert aircraft occupants of potentially harmful CO levels.

The device will work semalessly, says Garmin, with GTN Xi navigators, GI 275 flight instruments and TXi flight displays. Pilots can view the current CO level via a dedicated page or user data fields.

• Active carbon monoxide detectors mandatory in piston engine aircraft

In the event where potentially harmful CO levels are detected, the GCO 14 can provide both aural and visual alerts. Visual alerts flash a ‘CO Level’ or ‘CO’ message on the display. An aural alert, ‘Carbon Monoxide’ can also be triggered when the avionics are connected to an audio panel.

The small, lightweight GCO 14 module fits behind the aircraft’s panel. It can be attached to compatible avionics and includes the required wiring harness for installation.

The GCO 14 meets FAA TSO-C48A for use in certified aircraft and has a sensor life up to 10 years. When needed, the GCO 14 can be easily disconnected and replaced via a 4-pin connector.

• Four carbon monoxide digital monitors tested

The GCO 14 is expected to be available in Q2 2025 through Garmin dealers for a list price of $549.
