The Light-Line Head-Up Display (HUD) Evaluation is part of an exploratory program being conducted by the Air Force Flight Dynamics Laboratory, Flight Control Division (AFFDL/FGR), Wright-Patterson AFB OH, to investigate HUD systems/concepts to aid the pilot in maintaining a specified vertical path during visual landings. The HUD was evaluated at Randolph AFB by the USAF Instrument Flight Center, Research and Development Division (USAFIFC/RD), to determine the pilots' acceptance and operational utility of the Light-Line HUD from a pilot factors point of view. The Light-Line HUD shows flight path angle, angle-of-attack derived speed error, and lateral touchdown zone information in an easily interpretable form. The HUD (designed as a visual landing aid) provides the pilot a three-dimensional cue (light-line wand). The wand appears to be suspended in space emanating from the pilot's chest, and terminating on the desired aim point. The light-line display system which is focused at infinity, depicts a combination velocity vector (four strobing-line segments) and flightpath vector (transverse bar). Thus, the pilot is provided augmentive information without having to focus on the display. The wand has the capability to move laterally across the focal plane as well as longitudinally. This provides a realistic representation of the flightpath vector in three-dimensional space.
