Elbit Systems has performed a series of
successful demonstration flights using the BrightNite system, a
solution that enables utility helicopters to successfully perform
Degraded Visual Environment (DVE) missions in more than 90% of the
The goal of the flights was to demonstrate
the systemsí performance in DVE conditions, in moonless, pitch
dark nights, in which flights are rarely executed.
Dozens of pilots from a variety of Air
Forces around the globe participated in the demo flights. Installed onboard an Airbus Twin-Star
helicopter for the demo, the BrightNite system provided the pilots
with night-piloting capabilities similar and even exceeding to
those of attack helicopters.
The BrightNite solution comprises of
non-gimbaled uncooled FLIR and highly sensitive Complementary
Metal-Oxide Semiconductor (CMOS) sensors that present an
ultra-wide field of regard intuitive image to a display system
which projects to the HDTS, Elbit Systemís most common ANVIS/HUD
HMD with Line Of Sight capabilities).
The display is overlaid by a
synthetic layer that follows the contours of the landscape and a
third layer of 3D mission conformal symbology, which displays
hazards, mission conformal symbology and tactical data.
Multiple crew-members can simultaneously
scan the entire field of regard, using a single sensor and the
synthetic world, enabling them to fly any night.
Low-flying aircraft are
especially vulnerable to threats such as difficult terrain, enemy
fire and the intersection of utility wires in the flight path.
Sorties must often be carried out in a Degraded Visual Environment
(DVE), adding to the already heavy workload and leaving flight
crews to rely on NVGs to accomplish their mission. Factors
limiting the pilotsí FOV include: complete darkness, poor weather
conditions, brownouts, whiteouts and sandstorms.
to the U.S. Army Aviation there is a problem with spatial
disorientation while operating in degraded visual environments. Historically, approximately 20% of all Class A and B
mishaps have been attributed directly to spatial disorientation or
loss of situational awareness in DVE, but the issue remains far
Elbit Systemsí BrightNite overcomes these
visibility limitations and greatly improves situational awareness,
mission effectiveness and above all - flight safety in DVE. The
system processes real-time panorama video, enhanced by a 3D
conformal mission symbology concept and transmits high-resolution
video to the Helmet-Mounted Display (HMD).
unified location-based information culled from a wide FOV to
display crystal clear images, in zero visibility and zero latency,
enabling helicopters to successfully execute missions in more than
90% of the nights.
