You:<gulp> "Well, the helicopter descends and lands under full control."
Plaintiff's Attorney: Full control! That's interesting. Please tell the court, in your own words, just how steep and fast that "descent" is.
You: <gulp again> "Well, ah, I would say that it, ahhhhh, comes down like a, ahhhhhhhh, bank safe."
Plaintiff's Attorney: Bank safe?! Are you saying the "descent" would be nearly vertical?
You: "Well...ahhh...maybe not vertical. Maybe sixty...you know...degrees down. Not vertical. Depends on some things..."
60kts, 1500fpm - 60 degrees hey, I realise it feels like a plummet but that's the brain for you, its really a 1 in 3. As has been said before, ask a student how fast he'll think he descended vertically and he'll come up with something like 60-100 mph.
So glad its only robbies that have one engine, and single points of failure, so the rest of the smartasses don't have to worry about such things. I accept its low inertia head - was this a problem in this case - don't think so, but don't let facts get in the way
