Yep, fair point. From his original post, I assumed the incident was in an airfield or low ground environment. The only bit that really needs to go in the definition is the mention of ground effect.

And back to the original point. There is absolutely no problem if a helicopter is brought to a hover, whether a free air hover (air-referenced) or a geostationary hover (ground- referenced) provided;

A. Your downwash isn't causing an issue

B. You have the performance AEO and capability to safely stay airborne or safely land following eng failure (eg you are not sat in an avoid curve if it exists at that weight)

C. You are not exceeding any published limit.

I suspect you have been given an draft of some report to review as the subject before it's published. Definitely worth pushing back on it. If you're not getting traction, then elevate it through the organisations chain of command.
