Any wind is always to your advantage and the stronger the better. Makes it easier to identify as there are more cues. And in my experience I have never seen the wind blow into the ground. Steep approach to a site like that is textbook myth that unfortunately is still talked about. Pinnacle approach is much easier done climbing up to the site from below. If you run out of performance it will be patently obvious. The aircraft will turn around on its own to face back where you came from! The type of approach in the video without knowing your performance and verifying is just “suck it and see”. As with most things in aviation “ hope” is still not a good strategy! Seems that flight school must have been just a convenient lunch venue?
