Nuckolls, III) ________________________________ Message 1 _____________________________________ Time: 06:50:17 AM PST US Subject: AeroElectric-List: Re: Magnetized Dynon D100 Display From: "cskelt" Thank you Joe Gores as a 10 year old D180 and D100 of similar vintage presumably share a screen type, so this isn't a unique phenomenon. What Joe's data point can't tell us is whether his magnetism was always present or occurred recently, like mine, after years of non-magnetic functioning. In reply to Doug Windhorn's post, I removed the compass and D100 from the panel, opened up the D100, and folded out the display to persuade myself that the magnetism was in the display, not the electronics in the carcass, and to establish that it's permanent magnetism, not RF interference from live avionics. I used the panel mount compass and a hiking compass. The (admittedly rather cryptic) photos in the original post were intended to illustrate this. The threaded steel rod that locks the EFIS into the mounting tray does not appear to be magnetized. If these devices do indeed spontaneously magnetize, the need is for a demagnetizer, not a replacement screen, as the latter would be a relatively expensive and potentially only temporary fix.

I pulled the D-180 part way out of the instrument panel without disconnecting any cables. Then I moved the compass around. The magnetic interference seemed to be stronger under the instrument panel. Eventually I determined that the control stick is magnetized and attracts the south end of the compass needle. As I moved the compass around the control stick, the needle always pointed at the stick. Sorry about posting an incorrect data point yesterday. It is worth a try for Chris to try demagnetizing the steel locking rod with a soldering gun. https://www.youtube.com/watch?v=g2sFp5Blg_g -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501991#501991 ________________________________ Message 4 _____________________________________ Time: 02:33:48 PM PST US From: Jeff Luckey Subject: Re: AeroElectric-List: M43435/II/B Lacing tape What about these? https://www.amazon.com/dp/B00B4GCJV2/ref=sspa_dk_detail_5?psc=1&pd_rd_i= B00B4GCJV2p13NParams&smidAY1HFZHO49U&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUE yWThRSlY3WU9YR1BRJmVuY3J5cHRlZElkPUEwMDkyMjA3Uk9CQkY3UlFINjVMJmVuY3J5cHRlZEFk SWQ9QTA5Njg4NDMxUDdMUVEyNDdSOUxVJndpZGdldE5hbWU9c3BfZGV0YWlsMiZhY3Rpb249Y2xp Y2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU Ty-rap (tm) says they were invented to be used in airliners.

Out of curiosity, I have a D10A out of the panel - I was going to place it near my glareshield mount magnetic compass today to see if it produced similar results, but got sidetracked by other gremlins, so will have to wait until Thursday to do that check. Will let you know what I find.

Tye-wraps on the rovers would be at least tefzel if not nomex. Used work with a guy who was a big-time tech with an air transport maintenance firm. I'll see if I can track him down and ask about tye-wraps. According to the data sheet: http://www.aeroelectric.com/Mfgr_Data/Misc/Thomas&Betts/TY24MX_M3367.pdf intended for indoor applications. Rated to only 165F. These are made from 6.6 Nylon . . . not nearly the capability of Dacron. Virtually everything you can buy from the catalogs in tye-wraps will be nylon. Problematic under the cowl but okay every place else. >Is there something inherently better about lacing than Ty-raps? Tye-wraps ARE more convenient . . . but largely a personal preference. Bob . . . Un impeachable logic: George Carlin asked, "If black boxes survive crashes, why don't they make the whole airplane out of that stuff?" ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
