SWP, VRS and the Vuichard Method  

The formalization of the technique called the Vuichard method came out after I left my flight school as an CFI but our flight school owner was a former utility pilot so the concept had already been taught to all of us going back many years.  The general idea being sometimes you dont have the option of going forward, so it doesnt matter what you do, left right or even backwards you need to get the disc into clean air.  The earlier you feel it, the easier it is to get out of it.  Vuichard merely formalized it, gave it a name and has done a good job of pushing it through the industry but many people already were aware of the concept and been doing it for a long time.  

When it came out I was an IP for AS350's and I added it and taught both just to show the different options, but again prevention is the best medicine.  My former flight teaches both as well, the Vuichard just a more formalized version of what we were doing regarding alternative escapes.  

As always proper planning and flying to avoid it is best, but next to that early recognition and recovery is key.  Vuichard while it works well with IVRS (incipient vortex ring state) if you let or force the aircraft it deeper versions of it and get into god forbid full blown VRS which can be a terrifying experience then its not going to help you.  You will be making almost full deflections of the cyclic and aircraft just does not respond/mushes in other directions.  You just hope to fly out of it anyway you can before impact.
