The Cessna 210 crash thread was locked so I'll make a new thread to ask this. I noticed that one of the frames of video shows the vertical speed indicator and that made me wonder, what would the typical vertical speed at power off best glide be in a 210? I know it would vary by weight and density altitude, etc. But what would the ballpark be? From the video it looked like his vertical speed was approaching -1000 ft/min.
