# Zipline Autonomy (Acoustic Detect-and-Avoid), brain

Zipline's onboard autonomy stack and acoustic detect-and-avoid (DAA) system: a wing-mounted microphone array giving roughly 360-degree awareness up to about 2 km, plus ADS-B, enabling beyond-visual-line-of-sight flight without ground visual observers. Basis of Zipline's FAA BVLOS authorizations.
