The TCAS Resolution Advisory and Uberlingen: The Night the Machine Was Right
The 2002 Überlingen collision killed 71 people when one crew followed ATC instead of their TCAS RA - a failure of training, not technology.

FAR 91.113 and the Right of Way Hierarchy: The Pecking Order in the Sky That Every Pilot Must Know Cold
FAR 91.113 establishes a right of way hierarchy based on aircraft maneuverability - understand the principle and the entire pecking order becomes logical, not memorized.
PatternACAS X - The Algorithm That's Going to Replace TCAS II and Why the Airspace Needs It Now
ACAS X replaces TCAS II's 1990s-era lookup table with a real-time dynamic programming algorithm designed for drones, eVTOLs, and modern mixed airspace.
VectorTCAS Resolution Advisories and the Night Over Lake Constance That Rewrote Aviation's Chain of Command
The 2002 Überlingen midair collision killed 71 people and permanently established that a TCAS Resolution Advisory legally outranks an air traffic controller.
VectorThe FLARM collision avoidance system and why glider pilots built a traffic solution that works where ADS-B does not
FLARM predicts flight paths 18-20 seconds ahead, solving the mid-air collision problem ADS-B cannot address for maneuvering aircraft.
VectorClearing turns and the two three-sixty degree scans that keep you alive before every practice maneuver
Clearing turns are your primary defense against midair collisions before practice maneuvers - here's how to do them effectively.
PatternThe block method for scanning traffic and why your eyes are lying to you
The block scanning method replaces ineffective eye sweeps with focused, systematic checks that actually detect collision-course traffic.
