411 - "The subject aircraft was equipped with a HUD (as I recall), and if properly used, should greatly aid in the visibility department.
Comments from those that have used a HUD in the 737 might be interesting, in this regard."
The HUD has it's limitations. To think that it's the greatest thing since sliced bread was invented is silly.
Field of view issues. Lighting intensity issues, jumpiness of Flight Path Vector in turbulence, etc, etc.
