Gulfstream have had approvals allowing pilots using their enhanced flight vision system under FAA regs to descend to 100 ft above Touchdown Zone Elevation, below DA / MDA regardless whether it was CAT 1 or 2.
Having seen the system in action, it transmits a infrared image from the nose mounted camera and projects it on to the captains HUD..
Only took airlines about 15 years to catch up... Yeah yeah yeah, beancounters, lawyers, liability. You still can't deny that its still pretty cool...
I do wonder though which Boeings/Airbus aircraft have infrared installed? Would be handy at night picking your way through those dry tops in the Pacific at night....
