Hi Guppy,

First of all thanks a million for such an informative post. All that you've written made perfect sense to me and I could understand it, hopefully in a correct way. However I'm still a bit blurred by the direct relation to the mentioned V speeds.

To be it into use, for example lets assume my Vx is 100 knots (just want to reconfirm this is TAS and not CAS/EAS/IAS?) right after departure. As I climb towards the sky my excess power drops because of all the reasons you've stated above. Can't I then, reduce from 100 knots to compensate and give a better climb gradient as compared to what I would have should I continue the climb at 100 knots? Wouldn't that make Vx decrease?

Which part of this whole concept am I not getting it right?
