Radio Hangar explores TCAS to ACAS X, the Climb-Climb-Now Voice in the Cockpit, and the Optimized Logic That's Teaching Collision Avoidance to Turn Left Instead of Just Up.
VectorHow TCAS resolution advisories work, why the Überlingen midair changed the rules, and why pilots now trust the box over ATC.
VectorRadio Hangar explores TCAS, the Resolution Advisory, and the Automated Voice That Overrules Air Traffic Control When Two Airplanes Are Thirty Seconds From Hitting.
VectorACAS X is the FAA's next-generation collision avoidance system, replacing TCAS's hand-written rulebook with an optimized cost table.
VectorHow TCAS II lets two airliners coordinate a collision-avoiding climb and descent in seconds, why you always follow the RA, and what comes next.
VectorThe 2002 Überlingen collision killed 71 people when one crew followed ATC instead of their TCAS RA - a failure of training, not technology.
VectorACAS X replaces TCAS II's 1990s-era lookup table with a real-time dynamic programming algorithm designed for drones, eVTOLs, and modern mixed airspace.
