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.

Upon further investigation, I don't think my D-180 display is magnetized after
all. 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.

Ty-rap (tm) says they were invented to be used in airliners. And at a nickel
each, they=99re pretty reasonable.
Their literature cites applications on Mars rovers & Space Shuttle.
Is there something inherently better about lacing than Ty-raps?

Chris,
Thanks for the feedback on your experiment. 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.

Sincerely doubt that! 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?"
