I guess it depends on type, Saab 2000 will happily slow down with v/s up to 2500. Neutral torque flight idle descent ie 10-15 power units,which is about 3000 feet a minute 5.0 descent at 370kt Tas and will hit all the standard speeds ie 250 below fl100 230 in zone 210 on downwind 180 on base without touching power levers all the way down (950 rpm in crz pwr mode, no prop levers on Saab) maintaining 5.0 degrees with v/s as groundspeed slows. That's without even discing the props by closing the power levers let alone using the never normally used high rpm ice shedding mode which is 1100 rpm. So even with high rates of descent the Saab will slow. So keep our speed up please thank you and let us be number one please.. We can maintain 250 to final (if light short final) and still be stable through standard configuration at 1000 with a continuous descent. 3.0 CDA speed control is a no problem in this fine aircraft.
