is this a C2 model ???

[wbusiness]

No it is a model A. S/N 3

Your comment is a bit misleading. a turboprop's engine core is exactly the same as a jet engine. with a turboprop it uses the "thrust", that would normally be used to propel a jet forward, to power the turbine at the rear of the engine which is connected by a shaft to the prop via a gearbox. therefore the turbine takes the speed (energy) of the "exhaust" to power the prop thus slowing down the "exhaust" gasses leaving the engine. turboprop/jet/fan all have the same "core" therefore sound similar

With the strobing effect from the camera, it's pretty cool how you can see the pitch of the prop change as the rpms come up.

Turboprops and rain just work. Dunno what it is

Next time use a real camera instead of a cell phone to reduce the wind noise.

@xoio

It has nothing to do with safety, its just because pilots feathers the prop during shutdown to make the prop spool down faster.

You are still screwed if your brakes fail, no matter if you feather or unfeather the prop during shutdown.

Why the long face ????

[Zoloft61]

@billt460 that's what I wanted to ask aswell

[Zoloft61]

@uluuluululu that's not entirely accurate

[xoio]

To remove the risk of forward thrust. The moment the feather is reduced... the prop(s) will start to 'bite' & want to pull the plane forward...

Safety in case the parking brakes fail etc...

[billt460]

Why do turboprop engines always start with the prop fully feathered?

[ChrizRockster]

I come from an engineering background into aviation, so I base my comments on pure engineering fact. If your walking around the apron and say a turboshaft is a jet engine, a CAE will tell you otherwise.

If this person wishes to find out about turbines and so forth, they will do so independently from YouTube.

At least we are both focussed on providing information in our comments, lets be happy for that! 8o)

Happy Landings!
