The "other" does not

James Ruocco, F-35 chief engineer, told Inside the Navy during a May 26 interview at his office in Arlington, VA, his team performed an assessment two weeks ago at Naval Air Station Patuxent, MD, of the Gen III helmet's green-glow problem. Green-glow typically occurs when it is dark at night and makes it difficult for the pilots to see certain objects. 

As part of the assessment, the program set up a room at Pax to emulate the nighttime environment, Ruocco said. Testers compared the visibility of the current helmet and a helmet outfitted with organic LED technology and compared their visibility. "The difference being the advanced matrix LCD lets light leak in around the symbology. That's how you get the green-glow," Ruocco said. "The other one does not."
