Great question! It's better to leave the condition lever in flight idle until you've gotten the airplane sufficiently slowed. The higher NG at flight idle helps the propeller blades more quickly transition into beta, plus in the rare case that you do need reverse thrust the engine is already spooled and can deliver it immediately.
I am wondering how the PT6 engine produces reverse thrust at all, how the system works. Is the air exhaust (downstream the turbine) pointing towards the noise of the aircraft, which results in deceleration of the aircraft?
@@GeneStuart Thanks for the reply. Out of curiosity: Do you know how much the range of pitch of the prop is? Over how much degrees is prop pitch variable? And do you actually control the pitch itself, or is it done by software/mechanical link through the reverser-lever?
@@bernddasbrot2453 The prop feathers at about 80 degrees. The minimum pitch in flight is 6 degrees. And, the max reverse pitch is about -18 degrees. The pilot does not have direct control over the propeller pitch; it's controlled automatically by the propeller governor. The system works very similarly to governors on piston airplanes. Good questions!
