I'm interested in short, or trick, take-offs - such as from platforms, tall trees, etc.
I think that I should have
- a wind speed and direction measure
- an understanding of my wing surface area
This will let me add to my intuition from regular launches (from sites with known-good launch conditions), and estimate how much velocity I need to add via a run / push.
The methodology to count the wind measure seem a bit more grey, right now.
I can have a sense of the wind where I am, but it may quickly change beyond my launch site. Since I'm considering how to launch from a stationary position, it would be good to feed my senses / calculations more data like this.
