  1. I think you're going to need a bigger alternator.
  2. Well, those are really two separate issues. It seems likely that there could be over diagnosis of ADHD. I'm not really qualified to assess that. Assuming there is over diagnosis, is it caused by sugar? The research says it isn't.
  3. Is this what you're looking for?
  4. Does the CB pop when you first move the gear switch or once the gear is fully retracted?
  5. Fair enough. As scientists we rarely deal with absolutes. ADHD is a neurological issue and blood glucose spikes are primarily physiological but there's no denying the role of glucose metabolism on brain function. This isn't really my area of expertise either. My background is more general medicinal chemistry and small-molecule enzyme inhibitors. But, based on what I have seen ADHD appears to be primarily a neurotransmitter issue; specifically low dopamine and norepinephrine levels. Blood sugar spikes tend to increase dopamine levels. That combined with higher serotonin levels should result in a calming effect.
  6. ADHD is a complicated medical condition. My original point was that sugar is not a causal factor for that condition. Somehow this got sidetracked with short-term blood sugar level issues. If you are looking for a reason to not give kids lots of sugar it's obesity. Childhood and adult obesity is the number one health issue in this country and that is directly related to caloric intake.
  7. Did you read the link? "the studies to date found that sugar does not affect the behavior or cognitive performance of children. The strong belief of parents may be due to expectancy and common association."
  8. It certainly seems like it could but the studies just don't support it. Here's a decent meta analysis: http://www.ncbi.nlm.nih.gov/m/pubmed/7474248/ Might be related to increased serotonin release that occurs when blood sugar spikes. Either way, short term blood sugar fluctuations wouldn't be related to persistent hyperactivity in kids with ADHD.
  9. Have you checked with Dawley? They did a complete rebuild on my tailpipe for about $250. http://www.dawleyaviation.com
  10. Please provide a link or citation about this. I've never seen a legitimate scientific study that supports any of that. The link between sugar and hyperactivity has been debunked. http://www.m.webmd.com/a-to-z-guides/features/busting-sugar-hyperactivity-myth
  11. That's the runway in the background with all the emergency vehicles.
  12. It wasn't direct exposure to the fuel but rather the accumulated lead in the environment. There have been estimates that the average IQ of children in the U.S. has increased by 6-7 points as a result of banning leaded gasoline.
  13. Shimmy problems seem to typically be nose gear issues but in this case the problem occurs when braking so it seems like a brake problem on one of the mains could potentially be the source of the issue. Is it possible you have a warped brake disc on one side?
  14. Maybe the problem isn't directly related to the yoke position but rather the resulting position of the tail or one of the pushrods in the belly.
  15. If you have serious concerns about lead exposure you could take the industrial approach and create a chemical safety plan. Since you generally aren’t worried about addressing spills and other accidents the plan would probably have 3 parts: 1) risk assessment, 2) controls, 3) monitoring. The risk assessment is essentially what you are trying to do now. However, most of what you have gotten here is internet speculation so take it for what it’s worth. If you are concerned enough then your risk assessment conclusion may be that exposure is enough of a danger that you want to mitigate the risk. For hazardous chemical exposure, “controls” are used to mitigate the risk. Controls generally come in three forms: Administrative Controls, Engineering Controls, and Personal Protective Equipment (PPE). Administrative controls are policies and SOPs that try to minimize who might have exposure. In the case of Avgas one might establish an SOP that passengers (e.g children and spouses) will not be within 50 feet of the aircraft during refueling. Engineering controls in this might be related to containing the fuel within the fuel system. As was just mentioned you should ensure that fuel isn’t leaking into the cabin. PPE is used for people who must have contact with hazardous material. It is things like gloves and respirators which shouldn’t be necessary for a kid riding in a plane but for those who are concerned about exposure while fueling you should decide what level of PPE is appropriate. Monitoring in a case like this would probably be blood tests for lead. It would be best practice to have baseline tests so you can assess the exposure from the new activity. Some might feel a lot of blood tests might be invasive for a young child. A baseline for yourself might be useful and informative. If your test revealed no lead then you might be reasonably confident that a child would be safe in the GA environment. Disclaimer: Once again, I am a chemist not an MD or OHS specialist. I have worked with hazardous chemicals and safety plans but I am not an expert on industrial hygiene in general or lead exposure in particular. Everything here should be treated as a general opinion and not as a recommendation for your specific situation.
  16. I believe that for most children the harmful lead exposure from leaded auto gas came from the resulting large quantities of lead in the environment rather than acute exposure to the gasoline.
  17. The toxicology of lead exposure in general aviation is complicated by the fact that lead is present in multiple forms including tetraetyl lead in the gas as well as lead oxide and lead bromide in the exhaust. Exposure to the tetraetyl lead should likely be a non-issue as long as you keep her away from direct contact with the fuel. Exposure to lead oxide and lead bromide would probably be dependent on whether your exhaust system leaks. With a well functioning exhaust I would expect the lead salts to be dispersed pretty rapidly.

  18. At this point you don't even need a standalone WAAS GPS. NavWorx has a unit for about $2,500 that includes the position source and plugs into the back of your existing transponder (http://www.navworx.com/navworx_store/Certified_Aircraft_TSO_STC_ADS_B_Transceivers/ADS600_B.html ). With a box at that price point and $500 to cover labor I've already saved several AMUs by waiting.
  19. Have you tried the handheld radio with its regular flexible antenna inside and in close proximity to the plane? That might tell you if there's a localized EMF associated with the airframe.
  20. It's an incentive plan, not a reward plan. The goal is to encourage people to act who otherwise might not. Paying people who already acted wouldn't accomplish anything. If this program is successful it seems likely that they might extend it. What will they want in return? I'm pretty sure they will want you to have ADS-B installed.
  21. They seem awfully small for front-facing seats. I recall mine being in rear-facing seats until they were a year old. If their neck muscles aren't strong enough they could get seriously injured in an off-field landing.
  22. I can't seem to get a useful URL for the specific listing. If you go to http://www.barnstormers.com and search for "M20F" you should find it. Here is the text of the ad: GREAT CONDITION • $12,000 • FOR SALE • Mooney wing, 32 gallon tanks, no corrosion, taken off 68 M20F, delivery available, kept inside • Contact David Mathiesen - AIR-MODS AND REPAIR,INC., Owner - located Jackson, NJ USA • Telephone: 609 259 2400 • Fax: 609 259 1200 • Posted May 24, 2016
  23. 1500 RPM difference? You might want to get those adjusted.
  24. That same NJ MSC has an M20F wing for sale on Barnstormers...
  25. Vno is significantly higher for a J. You can hold a lot more speed in the descent without hitting the yellow arc.
