I've until now refrained from getting drawn into the argument about ROD of 200 ft/min at less than 30 kts being "VRS" territory, but seeing as it keeps on being mentioned.....
The Flight Manual for my aircraft states, in the "Normal Procedures" section:
STEEP APPROACHES AND VERTICAL DESCENT MANOEUVRES
Low speed steep approaches (up to 20 kts) and vertical descent manoeuvres should be performed with a maximum descent rate of 900ft/min.
That is copied verbatim. I expect the manufacturer also allows a bit for safety, as per the term "should", and so gives a conservative figure.
Nick, thanks for your patience on this subject
