Think I saw something that was maybe at a fixed weight.  Not the full Flight
manual table.  When I get home I'll look for it.   But I was suprised at the
data.  At lower altitudes it was over 4000fpm and was at least 2000fpm up to
and over 30000ft.  Finally dropped off to about 400fpm at 40000ft, reaching 0
somewhere around 43000ft.

Best,

Jim
