Startup procedures

[piosto]

I have a question regarding engine starting procedures. If I'm reading the checklists correctly, for a battery-powered start, the prop levers should be full forward. However, for an external power start, the procedure calls for the props to be in feather. The first scenario makes sense to me - it reduces the load on the starter - but what's the rationale for feathering the props when using external power?

The reason given was reduced noise and prop wash blasting the ground crew.

Thanks, makes sense.

Propeller position has negligible impact on starter load on free-turbine engines because there is no physical connection between the prop (RGB) and the engine (starter). That's why Garrets can't start feathered.
