the last thing I would be doing is going around when we got to decision height. Synthetic vision or not I would keep my head down until I was 50ft QFE then look up
When I did my IR test, the examiner made me fly to 50' before looking up. I called decision height, going around (as he hadn't told me to take the hood off) and he told me to continue. He also said "you fly it right to the deck or you will fail...keep those needles centered god damn it" (in jest I presume). At 50' he let me go visual...so yea it is possible and I agree it would be better to land on the airfield *somewhere* than to run out of fuel somewhere else.
We tried something similar with Synthetic vision, but didn't have the balls to land it, but I think it is very possible, especially as you get a momentum marker which shows your flight path. Keep that on the end of the runway and you WILL make the runway. It is dead accurate.
