It's a widely accepted practice in many parts of the industry here in OZ. However ... give plenty of thought to the surface you're on. We had a H500 chase a pilot off a (steel) ship's deck, before jumping on top of him & thrashing itself to death. The pilot was very lucky to walk away from that one. Also several mustering machines have burnt to the ground while the driver had his hand on his "other cyclic" releiving himself. "... well boss, it was like this"...
