Vertical Rates of Descent
I have tried a quick search through the forums but without success so here goes.
What vertical rates of descent are used in jet transports from TOD to approach?
Some years ago I was fortunate enough to visit the cockpit of a 717 for a brief time which included the top of descent. I recall the FO setting a vertical rate of 3,500' in the autopilot controller and then watching the glass VSI going to that rate (with the autothrottles retarding). Now that rate would be positively dangerous at lower altitudes so I presume a lesser rate is dialed in at some stage.
I know the TOD point is roughly 3 x altitude (in thousands) plus a fudge factor to get the beasty slowed but it is the rate that has me baffled. Any information greatly appreciated.
