I thought this was so cool that I had to post it. Pitlab has been doing some very nice work with their new AAT, OSD, AutoPilot firmware.
Here is an instrument landing in fog -- Pitlab has an ILS feature. I thought it was so cool that it may interest people. Not expecting the same functionality in Ardupilot (which I use). I am just posting it because I think it is a great feature. It would be great to have a more integrated OSD in Ardupilot.
