MPN11,
Never having flown either of them, I think I would prefer the "Step Down", as neither the operator nor I would have anything to think about other than keeping me on the line, and as the ranges (concentric circles on the tube) would be accurate, I could safely make the two descents as I was told at (say) 400/500 ft/min, confident that I was completely safe, and would have a few moments each time to settle down before the next stage.
Much less mentally stressful than having to chase a kind of "glide path" all the way down on top of everything else ! Would welcome input here from (dis)satisfied customers who've used the system.
Did we do them on the Link ?
Danny.
