Have not flown F.27 since 1973, but seem to remember the following:
Inital climbout speed 130KIAS, average 1000 ft/min (depending on temperature), cruise climb 140KIAS, average 700 ft/min to FL160, suggested EGT 730 C. (much better turbine life).
Would suggest for descent from FL075, 25NM, 140 KIAS, on final for ILS approach 120KIAS, over the fence at 100-110.
Also suggest that one NOT close the throttles
during descent as the backlash on reduction gears is not at all desired with the Dart engine. Generall VERY reliable powerplant.
Hope you find this helpful!
