I remember being somewhat confused by them on the FS9 B200. In the start up you start the right engine in Low Idle, then the right one to High Idle while starting the left engine, then both to Low Idle, then it says As Required. Well, someone who flies these things, What's Required?

Some of these turboprops seem happy just pushing the thing all the way forward and leaving it, some don't. I've never fully understood where to set them and why.

To make it simple start the right engine, leave it in low idle. Then start the right engine and leave in low idle.

Starting the right engine and putting it in high idle is if you are going to do a generator assisted start. I am going to take a very educated stab and say Carenado didn't simulate generator assisted starts so it wont matter anyway. I am guessing they didn't simulate the difference between low and high idle as it relates to the real pt6 so just use low idle and keep it simple.

On the real thing, want the condition levers back to either: improve fuel economy, or to assist cooling (say if you are holding for a clearance to enter the runway or something), then forward you want swifter throttle response.

 

You want the condition levers forward for pretty much everything else.

 

Some of that might not actually matter that much on the Carenado, depends on what is modeled under the hood, since it relates to how fast the engine is operating.

You confused me here

How so? aah right, got you, typo on my post hang on, I'll correct it. That's what you get for chatting to someone whilst typing LOL

The only real reason for having the fuel condition levers in high idle (which is just controlling turbine speed the engines will idle at - as the name suggests)... would be in a case where you have a short field and need some extra juice out of the reverse thrust. Aside from that, all normal ops usually have them set to low idle.

in addition hi idle is mainly used for a cross generator start to be able to crank the other engine

There are a few reasons to have condition levers higher tan low idle. Generator load for one. The higher the gen load (air conditoner or electrical heat in the king air 100 caused huge gen load) you need an higher N1 to sustain the load. Also at about 63% is where you obtain the coolest idle temps under normal conditions.
