Remote-mount sensor allows pilots to monitor CO levels and receive alerts
Garmin announced the GCO™ 14 carbon monoxide (CO) detector, 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 GCO 14 adds a new layer of situational awareness in the cockpit and provides peace of mind to pilots and their passengers, knowing the invisible threat of CO is being monitored.
The GCO 14 seamlessly integrates CO level monitoring and alerting into GTN™ Xi navigators, GI 275 flight instruments and TXi™ flight displays1. Pilots can view the current CO level via a dedicated page or user data fields. 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 and an aural alert, “Carbon Monoxide,” can also be triggered when the avionics are connected to an audio panel2. To supplement preset alert thresholds, custom advisories can activate a CO message at pilot-selectable limits.
The small, lightweight GCO 14 module fits easily 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.
The GCO 14 is expected to be available in Q2 2025 through Garmin authorized dealers for a list price of $549. For additional information about GCO 14, visit Garmin.com/GCO14.
