Situation vs. Command Guidance Symbology for Hybrid Landing Systems Applications

The Hybrid Landing System concept referred to in this paper, utilizes a holographic Head Up Display (HUD) as a precision monitor for a Fail Passive Autoland System. An industry group of researchers has evaluated two different concepts of HUD symbology that might be used to monitor an autoland system approach andlanding. Set 1 utilized command guidance (flight director) symbology. Set 4 was designed for the purpose of providing situation information instead of command guidance.
