Wing Watch
There you go. I was thinking this was another software based collision avoidance system that could false alarm and leave the flight crew in the dark. But the camera view solves that problem. Anything that gives the crew the raw data as an option and lets them be the final judge is better then a system leaving them dependent on ground based systems.
All too often, you depend on ground crew to watch your wings as you maneuver. But there's the Boeing employee who was run over by a towed plane that he was supposed to be watching demonstrating how ineffective this can be.
