I have recently been asked what the minimum Airspeed in RVSM airspace is? For all my manuals and plenty of requests to friends in the industry no one seems to know.
I ask anyone for an answer.

Try and think of the slowest a/c you think would be able to get to 290 and above.
Citation 500, Dornier 328, etc.
You often see ground speeds around 260-300kts at big levels
I'm sure some maths geek could tell us that there is a direct relation between lift and speed required in thin air

FAA document AppendixG to Part-91. doc rvsm minimum airspeed (www.faa.gov/ats/ato/150_docs/AppendixG_to_Part-91.doc+rvsm+minimum+airspeed&hl=en&gl=uk&ct=clnk&cd=1)
The airspeed flight envelope extends:
(i) From the airspeed of the slats/flaps-up maximum endurance (holding) airspeed, or the maneuvering airspeed, whichever is lower;
(ii) To the maximum operating airspeed (Vmo/Mmo), or airspeed limited by cruise thrust buffet, or other flight limitations, whichever is lower.
