Man is the internet cool or what, Here I am conversing with a guy in France. I remeber back in my young days as a boy growing up on a farm, that the idea of communicating with someone in France was either by ham radio or by being in the service and getting stationed in Europe.
OK, so some of the simple things in life thrill me. Remember , I said a boy growing up on the farm. Did I mention poor boy on the farm. Ok, to your subject. Magnetic shielding is a thin metal that I believe has a high amount of nickel in it. It is somewhere between aluminum foil and really thin sheet aluminum. You wrap the insturment in your panel that is causing the magnetic interference. The shielding must be at least 1.75 inches away from your compass. The method of finding the interferring source is to hold your vertical card compass in your hand ( level) turn on your master switch and radios. Then while holding your compass, pass it near all of the itmes in your panel and watch and see which one causes the compass to ms behave. Then wrap the offending insturment with the shielding material and wire tie it. Obviously this would be on the back side of the insturment. This seemed to work fine for me. You can buy the Magnetic Compass Shield ( MU Metal) can be purchased directly from Precision Insturments or from Aircraft Spruce. The part number is 11-00973 Hope this helps Jeff York Lexington, KY KR-2 Flying N839BG Home page http://web.qx.net/jeffyork40/ My KR-2 http://web.qx.net/jeffyork40/Airplane/ to see my KR-2 Email jeffyor...@qx.net ----- Original Message ----- From: "Serge VIDAL" <serge.vi...@sagem.com> To: "KRnet" <kr...@mylist.net> Sent: Thursday, April 27, 2006 4:22 AM Subject: Réf. : Re: KR> Vertical Card Compass Thanks for the info.

They are out of Chicago IL. There unit is FAA certified and I beloieve it is standard equipment in Pipers and several other aircraft. As far as working with the company that makes them. I have had a great experience with them. I wanted to mount mine back in the panel. The problem was that ther was magnetic interference with it in the panel. I made several phone calls to them and I believe I worked with a guy named John. They spent the time to help out me and my several year old compass and how to resolve my issue. The fix was installing magnetic compass shielding and they even recommended who I could get it from. I could not give a higher recommendation for a company and their product. Jeff York Lexington, KY.

I ordered one from AS a long time ago. It was the cheap one. It took forever to be delivered because it was back ordered for a long time. When it arrived, it did not work. I think they are usually very good if you spend the money. I did not want to spend that much money and am using the old air path. > > From: Serge VIDAL <serge.vi...@sagem.com> > Date: 2006/04/26 Wed AM 09:02:42 CDT > To: KRnet <kr...@mylist.net> > Subject: KR> Vertical Card Compass > > Has anybody got experience (good or bad) with Vertical Card Compasses? > > (Fore those who are not familiar with them, these are new type of > compasses that are proposes as a replacement for traditional oil-filled > compasses.
