PERSONAL CO detector kit for pilots. Carbon Monoxide (CO) is an extremely dangerous gas which can kill or incapacitate pilots when present even in only small quantities. It is colorless, odorless and has no taste. Deadly Carbon Monoxide (CO) is produced wherever fossil fuel is burned without sufficient oxygen present: AVGAS, jet fuel, diesel, natural gas, and propane. Piston-powered aircraft are only sometimes fitted with a CO detector, more often than not showing no replace-by date. They are useless and dangerous as most commercially available CO detectors lose their warning function after about 90 days. DESIGN 4 PIOTS has developed a personal PILOTCONTROLLER KIT® for the safety conscious pilot. This kit can be easily fixed to all DESIGN 4 PILOT brand and many other kneeboards featuring a stopwatch eyelet hole. Moveable arms as on a watch can be set to a precise replace-by date. The KIT consists of: 1 CONTROLLER holder, 1 Kneeboard socket for stopwatch eyelet holes on kneeboards, 4 individually packaged PILOT CONTROLLERS® detector refills.
