New Laser Obstacle Avoidance and Monitoring System

LOAM-V2 is the Leonardo new generation Obstacle Warning System, it belongs to the product family of active obstacle warning systems, as the previous generation Laser Obstacle Avoidance and Monitoring (LOAM).

Its design took advantage of the know-how and experience gained with the operational feedback of the LOAM operating on NH90, EH-101, and CH-47 helicopters.

Particularly compact in size at only 13 kg, the LOAM-V2 provides a lighter and reduced form factor (50% less volume, 30% less weight) to allow for the installation on smaller helicopters while featuring a number of brand new capabilities.

During flights at low altitudes, obstacles even of small dimensions, such as wires, are a real threat to the safety of flight, so LOAM-V2 supports operations under good and degraded visual environmental (GVE and DVE) conditions along the flight path by providing obstacle warning to enhance the situational awareness. LOAM-V2 can be seamlessly integrated with active and passive sensors such as radar, video cameras, fixed or steerable, visual or infra-red, as well as with systems based on obstacle static databases such as HTAWS and GPWS and digital maps DTED, DSM, DVOF.
