Why are there no overhead or rear facing windows?
Any light that is allowed to enter the cockpit will cause reflections and actually reduce visibility.
Detail: Most underwater environments are dimly lit because light filters down from the surface. This surface light must be kept out of the cockpit or it will cause reflections. It would be somewhat like driving a car at night with the interior light on. Anything bright in the cockpit would be reflected by the front windows, causing a ghost image to appear in the pilot's field of view.Does any one have info on certification for ambient dry subs. Also I
I ask this as most ambient designs seem to have steel or fibre glass hulls
and still have tiny view ports. and since to me the attraction of ambient
deisgns is the scope for larger less costly complex view ports and far
greater visibilty I was just wondering why no-one seems to have done this( I
could well be wrong)
