Many aircraft are equipped with warning systems to point out nearby aircraft and mountains; nevertheless, operators worry that there may still be crashes because these systems are operated beyond their limitations or undone by human intervention. As a result, researchers have this year tested an improved system that combines traffic and terrain avoidance and compensates for field of view limitations. These features are expected to provide aircrews with earlier warnings and more options for avoiding or extricating themselves from perilous situations.
