 Posted: Sun Oct 22, 2006 8:50 pm Post subject: EFIS D-10 Question |
 |
|
I know this should go to Dynon but I have a question on mounting the remote
compass module. The instructions say to mount this module as close to the
orientation of the D-10 unit as possible. Given that on an RV-6 the
instrument panel is tilted almost 10 degrees forward, wouldn't it make more
sense and be more accurate to mount it on the longeron line (which happens
to be the horizontal line of flight in cruise)? Why does Dynon say to mount
the compass at the same angle of tilt? Have you RV-6 drivers who've used
the remote Dynon compass mounted it with the tilt? Thanks.

The remote compass module works by measuring the components of the
magnetic field in three dimensions. Then, they use the aircraft
attitude to calculate the direction of magnetic north. The
calculation that the EFIS does assumes that the remote compass module
is at the same attitude as the EFIS. If it is not, the heading
accuracy will be reduced.

Greetings, Dean...
I've mounted them on two Rv6a's. One in the tail, but not fun to crawl back there to secure wires. On the other, I built a shelf just behind the baggage compartment which was pretty easy. Just used an angle finder to match the panel angle. At the time I wondered if this method would be accurate enough, but the D-100 performs flawlessly, so guess it was. BTW, Dynon wants the same orientation in all 3 axis... Again, easy to do with above method.
