Beware any assumption that having an enhanced vision system, particularly presented on a HUD, will enable pilots to ‘see’ and comprehend hazards.
NASA research with early HUDs (Dr Bray), demonstrated that most pilots did not ‘see’ a fuel truck crossing the runway. Also subsequent research on ‘HUD’ fixation, where the guidance cues can dominate the mental processes even if pilots think that they are flying visually and will ‘see’ everything.
What are the benefits of this system, improved minima over existing ILS, GPS approaches, better non-precision operations, takeoff minima etc ?
