2. PRODUCT OVERVIEW
This section provides a general overview of the various parts of the FlightDEK-D180 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.
FlightDEK-D180 Hardware
The FlightDEK-D180‘s versatile design accommodates a wide range of engines and sensors. You may configure the
system to meet your monitoring requirements covering both air- and water-cooled engines with up to six cylinders. Its
warning capabilities provide early notification of problems that might otherwise go unnoticed. The FlightDEK-D180
uses solid-state sensors to provide accurate and reliable information about your flying environment in an easy-to-use
interface.
POWER
The FlightDEK-D180 requires between 10 and 30 volts DC for operation and has inputs for an external backup power
supply and a keep-alive voltage. It is acceptable to have the FlightDEK-D180 turned on during engine start.
The FlightDEK-D180 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 FlightDEK-
D180. If the always-on Keep Alive circuit is connected, the FlightDEK-D180 continues to charge its internal battery
even if the instrument is turned off. This ensures that your internal emergency battery is always fully charged. 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 FlightDEK-D180 displays a low battery warning. When new, a fully charged internal battery is
rated for a minimum of 1.5 hours of normal operation with the FlightDEK-D180. If the FlightDEK-D180 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.
