Dynon Avionics EFIS-D10A Pilots Users Guide - Manual (Page 12)

Product Overview
EFIS-D10A Pilot’s User Guide 2-3
DISPLAY
The display is a 4-inch, 320 by 240 pixel, 450-nit LCD screen.
BUTTONS AND KNOBS
User interaction takes place via the six buttons along the bottom of the front panel of the unit.
When an AP74 Autopilot Interface Module is configured to control the EFIS-D10A, its VALUE knob changes
values when in various EFIS menus. When no menus are displayed the AP74 can adjust the barometer, altitude
bug, and heading bug. The AP74’s buttons control the Autopilot operation mode (Heading Hold, Track Hold,
GPS horizontal navigation, altitude hold), and allow you to engage and disengage the Autopilot.
When an HS34 is configured to control the EFIS-D10A, its VALUE knob changes values when in various EFIS
menus. When no menus are displayed the HS34 can adjust the barometer or altitude bug. The HS34’s
HEADING and COURSE knobs affect their respective parameters on the HSI page. The HS34’s GPS and NAV
buttons cycle through the available GPS and NAV sources connected to it.
ADAHRS Operation
The primary flight instruments on your EFIS display are generated using a group of calibrated sensors. All of them are
solid state – that is, there are no moving parts. These sensors include accelerometers, which measure forces in all three
directions; rotational rate sensors, which sense rotation about all three axes; pressure transducers for measuring air data;
and magnetometers on all three axes for measuring magnetic heading. These sensors form the core of Dynon’s Air Data
Attitude and Heading Reference System (ADAHRS).
The table below describes which inputs and sensors are used within the EFIS to generate the different displayed
instruments. It is not meant to enable in-flight troubleshooting, but is provided to convey how much of an integrated
system your EFIS is.
