Cruising speed for 1900D

<< < (2/3) > >>

EHM-2155 Mariano:
Cool, allright... that would do more sense then...

Thanks a lot for the help everyone!

EHM-1500 Jim:
Mariano, autofeather is more of a built in safety feature from what i can gather......it basically puts the blades of the prop parallel to the line of flight in some emergency situations i think. It has nothing to do with autothrottle.

EHM-1651 Christian:
The autofeather system, is monetring the engine torque output, and will if the torque of the engine drops below a level where it contributes to giving power to the aircraft, feather the propeller on the relevant engine. Placing the propeller blades in the postion where they create the lowest drag. So it's not a systems that control the engines in any way, just monitor the torque level on the engines. In case of a engine failure above V1 on a prop aicraft this sytem is redusing the time the failured engines propeller create extra drag, and therefore is a great safety enhachment.

EHM-1953 Daniel:
aha, so that's what the autofeather is doing, so it should be turned on all the time when airborn?

EHM-1651 Christian:
You won't need it on when taxing on the ground but I suppose it's turned on during the after engine start checklist, you must add some torque to test it to my knowledge. You can test how it works by shutting down one engine in midflight;)
