Carbon Monoxide Detector?
Another informal survey.
How many of you have, and use a battery powered Carbon Monoxide Detector when you fly? Why, or why not? -- Jim in NC |

I've flown many aircraft that have one of those stick-on type brown dots but I've never flown anything with a battery powered detector. I've also flown an old Apache with a Janitrol heater that would give you a headache every time you used it. I flew all that winter with a blanket on my lap. What can I say? Part 135 maintenance.... -- Mortimer Schnerd, RN VE |

Carbon Monoxide Detector?

when you fly? Yes. See it he http://makeashorterlink.com/?P4845270C It's small, and VERY sensitive. (It will sound an alarm in an extended climb, when the nose is high and the exhaust stream hits the fresh-air intake mounted way up at the top of the tail.) It's not cheap, but we fly all winter -- and I never trusted those dumb "Dead Stop" things to do anything... -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

Carbon Monoxide Detector?
I use several $ 2 variety "button" CO detectors. I started using them after
seeing a bunch of emergency vehicles surrounding a PA28 on the ground at Long Island MacArthur APT back in 1985. A couple from New England became unconscious during their taxi out. Leak was traced to a faulty heater shroud. They made it. Fortunately, they passed out before they took off. "Morgans" wrote in message ... Another informal survey.

The "why" should be obvious, particularly if you fly a single-engine airplane with cabin heat provided by the muffler shroud. The cardboard dots and most of the "Home Depot Specials" are almost worthless. You need an electronic monitor that will display low levels of CO, starting at 10ppm or lower, and alarm at those lower levels. The CO monitor that Jay Honeck linked to is a very good one. Aeromedix used to sell an imported Senco detector that alerted at low CO levels, but I believe that Senco went out of business or was acquired by someone else (this is the detector that I'm using). The key is to avoid the purchase of a detector that is UL listed or approved to US residential standards, because those detectors will alarm only at fairly high CO concentrations. JKG |

Carbon Monoxide Detector?
I looked up the AC article from Oct 2000. Here is verbatim what they
said. "The Underwriters Lab standard, which was recently revised upward, requires CO alarms to signal well ahead of the onset of symptoms for the "average" person. (That in itself may be a moving target, since response to CO varies by individual.) Specifically, UL requires an 85-decibel alarm signal to sound within 189 minutes if 70 parts per million CO is detected. If the level is 150 PPM, the alarm limit is 50 minutes and it's 15 minutes at 400 PPM. The old requirement was 90 minutes for 100 PPM and 35 minutes for 200 PPM. " About the dead stop spot detector; "Having seen these in dozens of aircraft, nary a one darkened, we assumed they were nothing more than a feel-good gimmick, albeit a cheap one. That's hardly the case, however. When exposed to CO in our test device, the Dead Stop turned noticeably darker after about five minutes of exposure at around 125 PPM, a low to mid-level of CO. At 500 and above, the patch darkens fast enough to watch, turning pitch black." Like a poster said, the electronic ones can be useful for finding leaks, and if you feel that the spots are not sensitive enough for you. But I think the spots have good value and are hardly worthless. Every airplane should have at least as much onboard. Jonathan Goodish wrote: In article , "Morgans" wrote: Another informal survey.

Carbon Monoxide Detector?
I use the same one as Jay - AeroMedix. Love the sensitivity.
Why battery over the "dots"? Allegedly the dots wear out over time (OK - so do batteries), but more because I value my life. Plus, being an engineer, it's fun to play around with it. In the winter with all the vents closed up, it's amazing to see how much CO comes in from the tailcone area. Just cracking a vent or cabin air or heat just a bit to produce positive pressure almost instantly removes the issue. "Morgans" wrote in message ... Another informal survey.

AVIATION CONSUMER did a report on the CO dot detectors back in the 80's or 90's. |
