Wow! Can't see those ones being anything else but RNAV!

It would be quite "interesting" to watch this unroll on a CAVOK day, let alone with any weather. Some years ago I remember watching a D-reg Seneca take off from LSZS (SMV, Samedan in Switzerland, 5600'ASL) in light snow, OVC<100'. He'd strapped a GPS-90 (remember those?) to the control column and programmed in a series of user waypoints that took him down the Inn valley between the peaks. The official departure reads something like "maintain VMC to 14,000'"...
