The US Air Force and US Navy are cooperatively developing and demonstrating a wide field of view, night vision,
helmet mounted cueing system called Night Vision Cueing and Display. This paper addresses the USAF path to safety
of flight qualification of the device to include assessment of the display quality, aircraft compatibility, environmental
tolerance, and ejection safety. The variety of tests accomplished will be briefly discussed to include key challenges that
were met and overcome. Also addressed is developmental and operational flight testing. Pilot assessments of the system
are discussed with emphasis on the aircrew interface and challenges with a newly designed, ejection safety enhancing
visor. Finally, joint service plans for the system are addressed.
