I couldn't find the answer to this in Bob's Rotary Wing 101, so I figured I'd just ask: what criteria has to be met to declare "Landing assured?" I hear it a lot from the medevac helos at the hospital as well as the business-helo and police birds coming in from elsewhere, and I've never known when they can say it and what it means as far as ATC services (the tower always seems to want to know)?
