Honeywell engineers are now developing a software upgrade for the AgustaWestland AW139 medium twin that optimizes the helicopter’s Primus Epic avionics system for the rigors of search-and-rescue operations.

The Phase 5 update for the AW139 cockpit recently underwent flight testing at Honeywell in Phoenix. It adds automated search patterns, automatic radar altitude hover, a “fly-up” safety limiter and other autopilot functions intended to ease workload and enhance safety for AW139 crews performing SAR missions in demanding environments.
