Own the Environment™

Degraded Visual Environment (DVE) refers to the loss of critical visual cues during flight whether due to weather, terrain or obscurants such as rain, snow, fog, dust, sand or smoke.

SNC’s DVE Solutions use multi-sensor fusion and Sierra Fusion™ advanced 3D world model to restore and enhance pilot situational awareness, improve flight safety and keep missions fully operational in conditions that would otherwise halt operations.

MISSION APPLICATIONS

DVE systems have the potential to revolutionize modern aviation for pilots, much like night vision equipment transformed military operations during WWII.

Helicopter EVAC

Medical Evacuation (MEDEVAC)

Enhances pilot safety and mission effectiveness during critical evacuations, enabling ingress/egress from conflict zones to evacuate and/or treat injured soldiers in hazardous conditions that previously grounded flights.

Sierra Fusion™ Advantage

Sierra Fusion, the 3D world data model powering SNC’s DVE suite, creates a digitally reconstructed, geo-registered operational picture that merges deep penetrating sensor inputs with mission tailored symbology. This capability delivers decisive clarity, faster pilot comprehension and enhanced survivability in complex flight environments.

By continuously updating the aircraft’s environmental reconstruction in real time, Sierra Fusion ensures pilots maintain reliable situational awareness even as conditions rapidly change.

Why is matters

Improved Safety

Real-time hazard detection
Alerts for terrain, wires, towers and aircraft
Enables precise maneuvering even in zero visibility

Increased Situational Awareness

Clear environmental visualization across all flight phases
Day/night performance in rural, urban and contested environments

Operational Readiness

Reduces diversions, cancellations and weather-caused grounding
Supports continuous operation in both military and commercial contexts
