Robinson Raven II Onboard Weighing System


Onboard Systems' innovative pin load cell technology has been incorporated into a new Onboard Weighing System for the Robinson Raven II aircraft. The kit is designed to work with the next generation of cargo hooks kits for the Raven II, which were STC approved in 2008.

Onboard Weighing Systems provide pilots with the exact weight of the load on the cargo hook via a display monitor mounted in the cockpit, allowing them to maximize load efficiency while reducing airframe stress. Pin load cells are designed to mount on one side of the hook by replacing the main attach bolt, rather than attaching as a separate link above the hook. This allows for improved ground clearance, easier cable routing and lower weight.
