Hi Cough,
You said very well protected ? is that secret information ? don't understand why ?
Well I just wanted to calculate the V speeds as they show in this video from the Baltic Air Academy.
I'm attaching the video here:

I'm not a real pilot, but when I fly simulators I like to be as close as possible to real pilots. It's the same if the chart hasn't 100% accurate data, but I just wanted to follow the procedure.
What really confuse me is what authority release those charts? Airbus? Navtech? FAA?
Cheers
