VRS recovery training  

In the old days we called it something different. A few years logging will teach you all need to now about recovery methods.  My guess is the accidents are happening when the recovery doesn't work.  I watched the  recovery method and it made sense on paper, in practice lots of variables to consider because its a helicopter. The old guys that taught us old guys always taught avoid the deadly 3.

1. engine developing power to the rotor

2. above normal Rate of descent.

3. Slow forward airspeed with a tailwind.

Eliminate anyone of the 3 and what you call VRS goes away.  I also think ground effect has saved a few pilots but not as many airframes.
