Aural Warning Products

The Ultra Aural Warning Generator (AWG) manages and provides audible warning messages to the pilot’s headset. The AWG acts as a secondary notification to the visual warnings generated in the cockpit system, greatly improving the pilot’s ability to absorb and act upon priority information.

The AWG interfaces with flight systems and the aircraft’s tactical processor via dual ARINC 429 and MIL-STD-1553 data bus. Commands are translated by the AWG into audio messages played into the cockpit audio system. Messages alert pilots to critical conditions, external threats and necessary evasive action. The AWG manages aural alert priorities, repetition and cancellation.

  • High integrity design to DO-178b at DAL C
