Not wishing to upset anyone... but has anyone ever seen a real prop move like that? I understand it's a nice visual feature, but I'm not convinced it's realistic.

If you move the pitch lever in real life it does that.

I've seen it on testing and demos..In normal operations it wouldn't be cycled as the prop would be started in the same position as it was stopped.

If a prop has a range of pitch and the lever is moved through it.. the blades will twist like that.

It's certainly NOT been done as a visual niceity that does not exist..and a lot of research was done to find out the correct angles


I'd never waste time on fictional animations

Seen it done a couple of times on different aircraft down at Shorts in Belfast as some sort of check. That was back in the 80's

When you hang an engine on the wing and install the prop, you're supposed to run the prop through its entire range of pitch (including reverse if so equipped) to ensure it is properly indexed on the prop shaft. Same for when you change props (happens much less often - you usually change the engine first and couple the prop change with an engine change).

Also, most good operators will run the props through completely with the engine off after an extended period of storage (30 days or more) if the engine hasn't been run on a consistent basis. This does 2 things - 1 it ensures that you have oil in the prop dome, and it ensures that your prop hasn't siezed up. It's much better to ensure the prop doesn't run away before you even start the engine.
