• You are perfectly correct Jan.

    (Since the 1978 San Diego crash where a 727 ran down a Cessna because the 727 crew had their seats too low and couldn't see the straight ahead view (with a murky horizon) it has been mandatory to properly use the seat height view reference indicators. There should be only one HUD viewing angle).

    I had my virtual seat too far back with my view excessively zoomed to compensate which narrowed my HUD display width.

    Seat back.

    Seat forward.
