| Subject: | Magnetized Dynon D100 Display |
Here's a really weird one that occurred recently. Flying on a North-Easterly heading
the PAI-700 panel mount compass informed me I was heading West. This is
a new problem and the photo taken some years ago shows the relative positions
of the instruments with reasonable agreement between the panel mount compass and
the Dynon EFIS.
Taxiing around a circle without the Dynon EFIS D100 in the panel gives good compass
readings. With the EFIS in place the compass reading remains between South
and West. I took the compass and EFIS to the compass manufacturer, Precision
Aviation, where they confirmed that the compass is OK and the EFIS magnetization
too strong for a mu-metal shield to help.
The next photo below shows a compass correctly pointing North and the second shows
it after rotating to point to the EFIS display, folded out from the box of
electronics and sensors. The magnetization appears to be concentrated halfway
up the left side of the display.
Dynon Technical Support deny there is anything wrong and my eventual request to
buy a replacement display went unanswered. This led to a google search for a
demagnetizer that found many plausible devices for up to a few hundred dollars
that's no doubt less than a new display. Can anyone advise if it's feasible to
demagnetize a display screen and offer any tips, or ideas as to how the display
became magnetized?
I understand that a standalone magnetic compass isn't required if you have an remote
electronic magnetometer but I appreciate the redundancy and the units did
after all coexist harmoniously for some years.
Thanks in advance!!

And yes, that pitot heat power is over half of my e-bus load. I don't see
myself continuing to fly in IMC with a primary system failure and would head to
VMC ASAP.
Since your B/U alternator has the capacity, did you implement the e-bus architecture
or put everything on a main bus?

This is indeed very odd. The D-100 case is made of alum, I think.
Anything inside could possibly be a power-supply coil, but that should
not be a permanent magnet. Long shot -- try to remove the battery pack.
How old is the D-100? Still under warranty?
I would be tempted to carefully use a simple demagnetizer. Radio Shack
used to sell them for something like $20. Tapehead demagnetizer.

Chris, this is a real puzzler! I'm sorry that
Dynon hasn't shown more interest in resolving
the issue.
I've dropped a note to John Torode at
Dynon (the head cheese). Let's see if he
is willing to be of assistance.

> Everything is a compromise. Copper tape can be used to create an antenna, the
more of the antenna that is vertical the better the performance. A BNC connector
can be soldered on to the foot, not sure how the ground plane would work,
perhaps it needs to be a dipole? I haven't been very close to anyone who has used
a tape antenna, but my impression was always that they required more maintenance,
and often have worse performance, than installed antennas. How important
is a reliable radio against saving weight?
Peter,
Thank you for your advice. Indeed the main point is having a reliable
radio, so the antenna (Bob Archer) will be in the glass fiber fin, as
originally intended.
I'll may be able to locate some quality smaller diameter coaxial with
acceptable performance as compared to our good old RG58.
Thanks for your help,

Thanks to all for the quick replies. It's not the battery -- I removed it and
checked. Nor is it the aluminum carcass that I also removed before partially
disconnecting the display and folding it down so the face rests on the bench.
The photo shows the compass pointing at the display with the back side up.
I'm as certain as I can be that the magnetism is "something" at the edge of the
screen. The Dynon unit is over ten years old and had 300 hours of faultless
performance behind it before this happened.
I've had excellent service up until now from Dynon--several issues with the EMS
were dealt with promptly and effectively. And the 360 degree taxi test with
and without the EFIS in place was suggested by one of the Dynon guys on the stand
at Sun-n-Fun.

Chris,
Just a thought here - have you tried to place the D100 near other compass
indicators to verify that the D100 is indeed magnetized? (The compass on
your iPhone (if that is what you have) is apparently not affected by a
nearby magnet!). Did you move it around and rotate it to see if the
apparent magnetism is localized at some point in the D100? Is it possible
that you had a steel screw or nut to secure the unit in place? What would
happen if you removed both units from the panel and positioned them in
various arrangements in magnetically benign area?
Just thinking out loud!

430
Certainly. Used, the market prices I've monitored over the past few
years are within a few hundred dollars of non-WAAS 430s. I've got an
SL40 in the panel now; I've considered purchasing used a VAL 2000 (uses
the SL30 protocol), and a cheap non-WAAS gps to go with it.
I really can't make any purchase make financial sense, but I need to at
least be able to deceive myself on the value.
