Flight test of a vision device

This paper describes flight test of a research external viewing device (REVD). The REVD was designed and down as a substitute for forward vision through a wind screen, constructed of optical lenses and mirrors, and evaluated during approaches and landings. A NASA F-104 aircraft hosted the experiment to enable 25/spl deg/ glide slope approaches. Additionally, conventional 3/spl deg/ glide slope approaches were down to evaluate the REVD for a hypothetical high-speed civil transport. The REVD was satisfactory for all approaches.<<ETX>>
