I'm thinking CTUN.DAlt is "desired" altitude. Is that correct? If so, I would think this, for an Auto mission, would be the altitude of my waypoints in my plan. Mine are 30m, but DAlt varies for every flight line, and in all cases is >30m. I didn't plot, but Alt and BAlt match rather nicely to DAlt--not the 30m I planned. Can someone explain the error in my thinking?
