Visual performance through a sample windshield segment of the B-1 aircraft

The stereopsis performance of 16 subjects was measured on an automated Howard-Dolman apparatus and compared with their performance through a sample segment of a proposed B-1 aircraft windshield. Recognition visual acuity was determined for 15 subjects using a low-contrast Landolt C target viewed with and without the segment. When the task was performed through the windshield segment, a statistically significant loss in stereopsis resulted, but no significant loss in visual acuity.
