Now Now thomas, long time no see, how are you doing.
one can definately recover incipient VRS.
One can definately put a machine into VRS and;
one can not hold it in because the upward rushing air will simply blow the recirculating air away. savvy??
all'a'same'as the limiting coefficient of static friction.
when one puts it into VRS, the relationship betwixt airframe and rotor disc can be safely maintained under full control to the highest integrity. fear not with an experienced person.
