FAR 91.113 establishes a two-part right-of-way framework - an aircraft-type hierarchy and four converging traffic rules - every pilot must know cold before checkride and before entering shared airspace.
PatternACAS X replaces TCAS's decades-old fixed lookup tables with real-time dynamic programming, cutting nuisance alerts and extending collision avoidance to unmanned aircraft.
VectorThe 2002 Überlingen collision killed 71 people when one crew followed ATC over their TCAS resolution advisory - the case that redefined automation authority in commercial aviation training.
VectorFAR 91.113 covers six distinct right-of-way situations - and most pilots only know one. Here's the complete hierarchy and how to apply it.
PatternACAS X replaces TCAS II's fixed 1980s decision rules with probabilistic optimization, cutting nuisance alerts 30–40% while maintaining collision avoidance performance.
VectorOn July 1, 2002, 71 people died over Uberlingen when a crew chose ATC over a TCAS Resolution Advisory - here's why that rule is absolute.
VectorACAS X replaces TCAS II's fixed logic tables with probabilistic optimization, reducing nuisance alerts and enabling collision avoidance for unmanned aircraft in shared airspace.
VectorThe 2002 Uberlingen midair killed 71 people after one crew obeyed ATC over their TCAS RA - here's why the engineering demands full compliance.
VectorThe 2002 Überlingen collision killed 71 people after a crew chose ATC over a TCAS Resolution Advisory - and permanently changed how aviation trains pilots to trust the machine.
VectorThe 2002 Überlingen midair killed 71 people when a crew followed an ATC instruction instead of their TCAS Resolution Advisory - and changed how the industry trains pilots forever.
VectorOn July 1, 2002, 71 people died over Lake Constance when TCAS issued a perfect coordinated advisory that one crew overrode - a lesson every pilot must understand.
VectorACAS X replaces TCAS's fixed decision rules with a precomputed optimization algorithm, reducing nuisance alerts and scaling to drones, eVTOLs, and increasingly complex airspace.
VectorACAS X replaces TCAS's fixed logic tables with probabilistic algorithms, cutting nuisance advisories by 40–50% while handling drones and eVTOLs alongside manned traffic.
VectorHow TCAS works, why a resolution advisory overrides ATC, and what the 2002 Überlingen disaster teaches every pilot about trusting the box.
VectorFAR 91.113 right-of-way rules explained: who yields when two aircraft converge, meet head-on, or overtake - and why yielding beats being right.
PatternA pilot's plain-English guide to FAR 91.113 right-of-way rules: who yields in converging, head-on, overtaking, and landing situations.
PatternRadio 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.
VectorLearn who yields under FAR 91.113 right-of-way rules - converging, head-on, overtaking, aircraft categories, and landing priority.
PatternHow TCAS resolution advisories work, why the Überlingen midair changed the rules, and why pilots now trust the box over ATC.
VectorUnderstand FAR 91.113 right-of-way rules so you know instantly who gives way when two aircraft converge, meet head-on, or overtake.
