I spent some time in the G1000 Caravan sim at FlightSafety today, using only the Garmin synthetic vision depiction of the runway to make dead stick approaches and landings to a 100 foot ceiling, by placing the flight path marker over the approach end of the runway, just as we use a spot on the windshield to make a precision autorotation. This technology is amazing and makes the Collins Pro Line 21 avionics I flew, the three previous days in the sim, seem antique by comparison. Whether on the Garmin G500H or G1000, synthetic vision will offer incredible capability to those flying at night, and/or in low or mountainous conditions.
