GPS spoofing is actively corrupting ADS-B surveillance data in live certificated airspace, creating false position pictures that controllers and pilots may have no immediate way to detect.
TIS-B fills ADS-B traffic display gaps using FAA radar data, but latency, coverage holes, and non-transponder aircraft create blind spots every pilot must understand.
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.
