Thanks for producing another of your superb graphics,
HN39. Prior to that, trying to get my head around your written description was only partially successful, and cost me several minutes sleep at bedtime!
The mists are now slowly lifting,
although you haven't drawn us a sample tangential line. 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? But what if headwind equals TAS
(see Cpn Bloggs et al)?
Don't worry, you'll get us there in the end.
