2. PRODUCT OVERVIEW
This section provides a general overview of the various parts of the EFIS-D6 as well as a theory of operation. The
information in this section serves as a reference only and helps familiarize you with the inner workings of the unit. It
should not be used for diagnostic or reparative work.
EFIS-D6 Hardware
The EFIS-D6 uses solid-state sensors to provide accurate and reliable information about your flying environment in an
easy-to-use interface.
POWER
The EFIS-D6 requires between 10 and 30 volts DC for operation. It is acceptable to have the EFIS-D6 turned on during
engine start.
The EFIS-D6 can be ordered with an optional internal battery which allows the instrument to continue to operate in the
event of an external power failure. This lithium-ion battery is rechargeable and is managed by the EFIS-D6. Under
normal conditions, the internal battery should have a voltage between 13 and 16.8 volts. When the battery’s voltage
drops below 13 volts, the EFIS-D6 displays a low battery warning. When new, a fully charged internal battery is rated
for a minimum of 2 hours of normal operation with the EFIS-D6. If the EFIS-D6 has switched to its internal emergency
battery due to a power loss in your aircraft, it is advised that you land as soon as possible.
SENSORS AND INPUTS
EFIS-D6 Pilot’s User Guide 2-1
Attitude information is obtained from 3 solid-state gyrometers, 3 solid-state accelerometers, and the airspeed pressure
sensor. Heading information is obtained from 3 solid-state magnetometers housed in the EDC-D10A. Airspeed, altitude
and angle of attack are obtained from three separate pressure transducers.
