I am working though some calculations and need the sink rate as a
function of speed with the spoilers fully extended. Does anyone know
of such data for a glider? How do spoilers extended affect sink rate
as a function of speed?

I have one data point for the ASW 19B. Gear down, full airbrake, IAS
90kts, sink 3,300fpm. Flight data 4/20/91 EW barograph.
