6-2 EFIS-D10A Installation Guide
forum.dynonavionics.com – Dynon’s Online Customer Forum is a resource for Dynon Avionics
customers to discuss installation and operational issues relating to Dynon Avionics products. The
Forum is especially useful for pilots with uncommon aircraft or unusual installation issues. For
customers that cannot call Dynon Technical Support during our normal business hours, the
Forum is a convenient way to interact with Dynon Avionics Technical Support. The Forum
allows online sharing of wiring diagrams, photos, and other types of electronic files.
Dynon will continue to develop kits and installation instructions for more aircraft based on
demand. It is also expected that aircraft manufacturers will develop their own mounting kits for
Dynon servos or offer the Dynon AP as a factory option. If Dynon does not currently offer a
mounting kit for your particular aircraft, and you would be inclined to assist in developing a kit
and documentation, please send an introductory email message about your interest to:

DSAB Firmware Compatibility
All Dynon instruments connected via DSAB must be running the same firmware version
(currently version 5.4). This applies to the servos and AP74 as well. Because the servos
and AP74 are updated via the DSAB Bus Master EFIS (the EFIS that you wish to control
the AP, and from which you run the CONFIGURE DSAB command), wait until
complete mechanical and electrical installation before performing the software upgrade
steps. See Firmware Upgrades Required For AP Functionality on page 6-13 for more
information.
Compass Calibration Critical For Certain AP Modes
The Dynon Avionics AP requires an accurate magnetic heading to operate efficiently
and comfortably in HDG mode and the radio-based VOR/NAV mode. Therefore it is
critical that the aircraft’s compass be installed correctly, calibrated, and operating well in
all attitudes. If you currently have an EFIS-D10A, and are only using the internal
magnetic compass, Dynon strongly recommends the installation and use of the EDC-
D10A remote-mounted digital magnetic compass, and properly calibrating it per the
instructions found in Chapter 4: Instrument Installation.
If the Dynon Avionics AP will be used exclusively in GPS NAV or TRK modes, then absolute
accuracy of compass data is somewhat less critical as part of AP operation. But if NAV/GPS
data is lost due to an equipment failure, bad data, loss of signal, etc. the AP will “fail over” to
HDG mode, which uses the magnetic compass data as its source.
