I'm stuck dead center of the zone (Redhill). I have one student at the right stage in his training whom I will allow solo on his own if he wants to do it. My other students are either not ready or not consistent enough. I don't think I will be comfortable allowing anyone to do a solo landaway though - just too many things to get right and they don't need the additional pressure.
Mind you, I haven't yet tried to fly in the zone myself so I don't really know what it will be like. My first flights are scheduled for Sunday. Hopefully Redhill will be more of a hill and less of a lake by then.
