OK maybe its the tone and the written word, but the last one is far more effective.
Vy does not give you as much inertia and as has been explained to me, and shown by in flight testing with Chuckles a far better real world transition to best glide and successfully achieving the impossible turn.
One point of course....KNOW YOUR AIRCRAFT.
With many types as you no doubt fly this is a vast and wide experience base, but it would be interesting to get your results of tooling around experimenting. Maybe you do not get the opportunity to do that as much as you might like.
While Vy is the best rate, the trade off for a few extra knots in terms of speed and thus kinetic energy (1/2MV2) is that you get much more energy for very little loss in ROC. It is all about losses. Someone has already mentioned best L/D.
If I can get JD to drop a line he will explain it far better in far fewer words. I have flown with Chuckles in a Bonanza where he demonstrated this perfectly. I can't argue the results, simple as that.
The initial climb is in my view only a few hundred feet, of me it is until the turn back is so easily achived it is easy. In my a/c that is 400', others could be 1000'. Know your aeroplane. After that Vy is not optimal at all, somewhere above best L/D is better across the board. The transition from where the nose wheel breaks ground (or TW) to the point above 1000' is a gradual progression. To think of it as Vy all the way is not realistic.
would you climb all the way to 5000 feet on the edge of the blue line in a twin? No.
I said before that there is some learning to be had from a google search, well I got sucked in and did it for the benefit of the silent majority.
Enjoy this.

I hope everyone enjoys and learns something from these. Use critical thinking.
I am blessed I tell ya for my privileged of friends such as these.
