format. Please refer to the EFIS-D10A Installation Guide for instructions on how to connect these devices to your Dynon
network. Also ensure your GPS device is configured to output magnetic headings since all calculations and displays are
done in reference to the local magnetic heading.
Accessing the HSI/DG Page
The HSI is displayed as a full-screen page on your EFIS-D10A. If the HSI is defined as part of a screen setup in your
rotation, display the HSI page using either of the screen rotation hotkeys (buttons 1 and 6) until the appropriate page is
displayed. If the HSI screen is not in your rotation, you can access the HSI by holding down the right button and
navigating to the HSI screen. See page 3-2 for more information on screen configuration.
All HSI screens in a DSAB network share their configuration and are identical to one another at all times.
Changing the source of information on one HSI page affects all units, as does changing scaling, bugs, or bearing
pointers. It is not possible to show a NAV radio on one screen and a GPS on another screen.
HSI Display Basics
There are three possible sources of information on the HSI page: GPS, NAV, and internal EFIS data. It is important to
know what equipment is sourcing your data, so most displayed data is color coded so that it is easy to identify the source
of the data. Data that is sourced from a GPS unit is color coded in magenta, and includes course direction, course
deviation, vertical guidance, ground track, ground speed, altitude, distance to waypoint, and other data. Data that comes
from a navigation radio (VOR / LOC) is green in color and includes the course, course deviation, glideslope, nav mode,
to/from, OBS setting, tuned frequency, station identifier, and more. The final data source is information that comes from
the EFIS itself and is color coded in white. The EFIS-sourced data includes magnetic heading, true airspeed, winds, and
various other data points. Below are some of the basics
