Thanks HN39,
Nearly all of that makes sense. Still unhappy on one point that I raised earlier:
Do I infer correctly that at a thrust/weight ratio of, for example, 0.2, a H/W of more than 30m/s (60kts) does not further improve my chances of missing the top of the mountain?
My reference to the looming mountain range was rhetorical, of course. But you are talking about tangents, and I cannot draw a tangent to any of those T/W curves from any point on the x-axis to the right of about 30m/s. Do you see what I mean? So how do we find the best climb speeds for the various T/W ratios when H/W > 30m/s?
