Citing the limitations of “the see-and-avoid concept of traffic separation,” the U.S. National Transportation Safety Board (NTSB) has issued a safety alert, a series of animations, and a pair of safety recommendations, all aimed at preventing midair collisions.1
“The see-and-avoid concept has long been the foundation of midair collision prevention,” the NTSB said in its safety alert, issued in November. “However, the inherent limitations of this concept, including human limitations, environmental conditions, aircraft blind spots and operational distractions, leave even the most diligent pilot vulnerable to the threat of a midair collision with an unseen aircraft.”
