that allow pilots to find the most efficient route for
improved fuel efficiency and passenger safety.
Enhanced Awareness
The RDR-4000 weather radar uses volumetric
3-D scanning and pulse compression technologies
to provide a more complete view of the weather
across a 320 nm detection range ahead of the
aircraft. The
system’s vertical
display capability
combines both
weather and terrain
data to provide a
more intuitive
horizontal and vertical view of upcoming weather
dynamics, reducing and eliminating any
unnecessary route deviations. For more tactical
weather views, pilots can select individual slices
of the airspace, including specific range, azimuth
or altitude displays, to make more informed
routing and strategic maneuvering decisions.
Simplified Operation
Designed to be fully automatic, the RDR-4000
does not require any manual adjustments to the
system or antenna for operation. To reduce pilot
workload, general weather detection is based
upon the flight path data with constant updates
of the latest hazard assessments provided on the
display screen. The system also improves cockpit
efficiency by extracting ground clutter via an
internal terrain database and automatically
correcting for the earth’s curvature on returns to
ensure the clearest, most accurate view of the
weather ahead.
Turbulence Detection
As the first and only radar system certified to the
FAA’s Enhanced Turbulence Detection Minimum
Operational Performance Standard (MOPS), pilots
will be better informed of air turbulence and have
the ability to make safer, more informed route
decisions due to weather. This advanced
protection also helps minimize passenger
concerns and the potential for turbulence related
costs due to injuries and aircraft inspections.

Cost-Effective Design
Using only 3 MCUs, our highly compact radar
system provides more than a 50% weight
reduction, allowing enough space for dual system
installation in less space than a current 8 MCU
system. This weight and space reduction can
provide as much as $10,000 per year per aircraft
fuel savings and allows for the additional avionics
space to be allocated for other equipment needs.
The RDR-4000 also does not require waveguides,
which reduces maintenance costs by eliminating
waveguide runs and switches.
This advanced design feature also improves
overall radar performance and system sensitivity
by reducing RF signal loss to and from
the antenna.
With improved diagnostics, the system requires
less repair time and labor, which can result in over
a 30% reduction in maintenance costs, with lower
spares provisioning required. Additionally, our
advanced radar processor and antenna drive
components increases RDR-4000 system
reliability, which can directly decrease operating
expenses by at least 30%.
