aircraft to gain access to the wire bundles.
Q: Can this system be integrated with
a legacy (analog) system or must
the system be replaced?
A: The AMU has an ICS Tie Line port
that allows the system to be expanded
and/or connected to other units. Using the
DevCS, the ICS Tie Line can be set for
digital or analog operation. In analog
mode, the ICS Tie Line can be connected
to legacy products.
The capacity for numerous radio and
audio inputs, the flexibility built into the
design, and the expandability of the sys-
tem ensure that DACS will provide suffi-
cient service for the life of the helicopter.
Crystal clear digital audio with no static
or bleed-through tops the list of why this
system will be in high demand.
Although a relatively new product about
to be released on the market, DACS has
reached an industry accepted state of ma-
turity. With installations now completed
and certified by both OEM’s and comple-
tion centers, the system has been flying for
over two years and is proven in nearly 100
installations across a number of airframe
types. In all instances, DACS has been
given a unanimous thumbs-up for the sys-
tem’s simplified installation, enhanced
performance and configurability for spe-
cial mission and tactical operations.
