Autorotations with tail wind.
My two pennorth.
Inadvisable ... final flare has reduced cyclic responsiveness and quite likely to result in a higher speed 'run on' with increased risk of roll over.
However, when teaching advanced emergency handling, there is a school of thought that says 'providing there is a reserve of height ... and particularly where the surface offers minimum landing site options ... following the failure, it can be preferable to initially 'Turn downwind.'
The procedure allows the heli to cover more of the surface and provides greater selection of suitable landing sites. Always providing the heli is returned to an 'into wind' position for the actaul touch down.
I teach the method when offering mutual advanced continuation training to interested pilots.
Happy and safe flying out there.
