On the Tucano we fly a descending finals turn from the end of the d/w leg to a "300' pt" on the extended CL.
On the finals turn: pwr=ROD, pitch=IAS (for a constant IAS).
On the final app: pwr=IAS, pitch=Flight path (for a constant flight path).The aim on fin app is for a steady spd decay from 110kts to Vth (90-95kts).
This concurs with the above msg in that when you have an aiming point pwr=spd and pitch=flight path.
