What to do if carbon monoxide is present?

Most small, single engine aircraft are fitted with non audible carbon monoxide detectors that turn black if it is present.



Carbon monoxide can incapacitate in mere seconds (and kill in minutes) depending on the ppm.



If you are cruising at 12,000 feet, that is not enough time to land.



So what should you do if you see a carbon monoxide warning (and begin to feel the effects of it)?

    Those dot-style detectors aren't anywhere near as good as an electronic one, you may want to consider having a compact one in your flight bag. If you do use the dot-style ones make sure it's in date as part of your pre-flight check.

    Just about the only situations where the dot-style detectors could be reasonably expected to serve any useful purpose (whether on aircraft, or anywhere else) would be when there is a slowly-forming leak which doesn't yet pose a danger. Electronic carbon monoxide detectors with alarms and multi-year batteries have gotten so cheap I can't really see much reason not to have one.

The first thing you're going to want to do is get fresh air into the cabin, by ensuring the vents/windows are open. This will dilute the amount of CO in the cabin and relieve symptoms reasonably quickly - allowing you time to land as soon as practical.



There is also some good information online which contains further advice:





  • Turn the cabin heat fully off.

  • Select maximum rate of fresh air ventilation to the cabin.

  • Open windows if the environment, flight profile and operating manual permit.

  • Consider using supplemental oxygen if available and if doing so would not introduce another safety or fire hazard.

  • Land as soon as possible/practicable.

  • Inform Air Traffic Control of your concerns and intentions.

  • Select a leaner fuel mixture if possible.

  • After landing seek medical attention as soon as possible.

  • Before continuing the flight, have the aircraft inspected by a certified mechanic




If you're wondering about the first point, the reason is that the cabin heat is the primary way CO enters the cabin of light aircraft.




Typically most piston powered aircraft obtain their cabin heating by directing fresh (ram) air over the engine muffler (silencer). If there are any cracks, holes or poorly fitting components in the exhaust system, then CO-rich exhaust gases can enter the cabin. Engine exhaust may also enter the cabin through inadequately sealed firewalls and wheel wells etc.

    If you get symptoms don't trust that they will go away quickly. With fresh air ventilation CO has a 4-6 hour half life in the blood. It binds very strongly with hemoglobin, so it takes a long time to get rid of it

    Also note, that CO2 is heavier than the air and CO is lighter. CO2 tends to concentrate down and CO tends to concentrate at the top. Strong CO-hemoglobin bond - stronger than O-hem and much stronger than CO2-hem, is the killing feature here - it prevents oxygen to be absorbed in the blood. Get rid of the air around the head ASAP.

    @Crowley I don't believe that the stratification of CO and air is significant with the natural air currents you get in an airplane. In fact, it's not significant with the currents in your house, which is why there's no preferred height for CO detectors.

A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

Image
0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{...
