Carbon Monoxide in Piston Engine Aircraft

The CAA has been actively engaged on the topic of carbon monoxide (CO) in general aviation (GA) over the last three years and has undertaken multiple initiatives to raise GA pilot awareness of CO as well as the various prevention and detection measures that can be taken to mitigate the risk. A key focus has been on commercial off the shelf CO detectors with alerting capability, which can provide low-cost, effective CO detection in piston engine aircraft.

The CAA has developed this consultation to understand stakeholder views on several key topics, including:
the main barriers pilots face in obtaining an active CO detector, the role that maintenance plays in combatting CO, the importance of protecting passengers from CO, and whether active CO detectors ought to be mandatory for some operations.
