Feathered Propeller Animation

MD82

Hello,

I was wondering if, when time permits, the feathered prop animation can be updated. It's hard to find reference videos online because the recording frame rate interferes with what you actually see. But when a propeller is feathered, like in the Starship's example at around 340 RPM, the blades will look coarse, and you can just about see them spinning. In the Starship now, even with the prop fully feathered and indicating 340 RPM, you will see a flat, fast spinning disc. Mostly the same as if you were out of feather.

I have not yet had to feather the prop in flight.The dukes implement this very well animation-wise iirc. So if that what describe is the case, it is hopefully fixed soon

Do you have any tips on when to adjust feather during flight phases? What setting do you want for extracting maximum speed during cruise? What do you want for max efficiency during cruise?

I have a feeling there might be a chart somewhere for this.

The actual feather setting is only for start and shut down. As for prop pitch. The manual has your answer. I suspect there may be more settings, but the base is. Full forward (1700 RPM) for takeoff, then bring it back to 1600 for the remainder of the flight. Remember to keep ITT's below 840.

Do you keep your ITT lower by reducing the throttle as you change the pitch?

Set pitch to maintain 1600 during climb and leave it there. Everything after that is done by throttle movements, including reduction to keep ITT in line with the max.

@Marionettework As @jmarkows says. There are power setting tables in the manual. For climb you set 1600 and forget it. Use only the power levers to maintain table torque until ITT becomes limiting.
