This is a great topic. In my primary training, we were required to demonstrate VRS and recovery prior to soloing, and also on our check ride. However, at the RHC course, I realized how inadequate this training was, and figure that during training there was probably a bit of confusion about the vibrations around ETL and incipient VRS. At RHC, the recovery that I'd been doing was completely inadequate.
In the spirit of trying to improve training, I've been publishing lesson plans in a form that allows experienced instructors to provide input for new instructors and students. Check the
VRS lesson plan out here, and please add your experience.
