The FAA has just published a new edition of the Helicopter Flying Handbook, which gives pride of place to Vuichard for recovery from incipient Vortex Ring (page 11-10). Given the popularity of Vuichard shown on this forum, I thought people might find that interesting.
The reaction on the FB helicopter pilot group has been 100% positive of the form "hey, awesome Claude". Personally I have no opinion, but then I only fly R44s in which the concept of having an excessive of power is something to dream about.
