160525-N-PO203-302 BEALETON, Virginia (May. 25, 2016) A Bell 206 helicopter equipped with the Office of Naval Research-funded Autonomous Aerial Cargo/Utility System (AACUS) sensor suite avoids obstacles while coming if for a landing during integrated flight testing at the Flying Circus Aerodrome located in Bealeton, Va. The AACUS program is developing an innovative capability that when installed in existing rotary-wing aircraft enables autonomous obstacle avoidance, approaches, landings and takeoffs to and from unprepared landing sites.
