from the Kurt Yoda's tuto I can read both the fuel boost-pumps switches are ON from "Before engine starting" c/l until "Shutdown and securing" c/l

 

can anyone confirm this is correct ?

Hi Jean-Louis,

I am no real world King Air pilot but as seen on different C90B Checklists and some answers about this , this should be they way it is done in real-life. I was wondering myself :Thinking: regarding this. But yes, on before enginestart and off after N1 < 10% on shutdown ...

"... this should be they way it is done in real-life........" Thanks very much Andrea

 

page 15 of Yoda's tuto : " You shouldn't leave the pitot heat, fuel vent heat, or windshield heat on while on the ground, since you may burn out the heating elements "

 

the problem is that pitot heat, fuel vent heat, or windshield heat are never switched to ON at any time ??? Just something missing in the "Before Take-Off" c/l you should be aware of

Just something missing in the "Before Take-Off" c/l you should be aware of

 

Not missed - just stated generically in the Before Take Off list: "Ice Protection - AS REQUIRED. Here's where I'll pretty much always flip these three switches.

 

As for the boost pumps, they stay on until shutdown.

Yes, keep the boost pumps on from before engine start to after shutdown when the Ng drops below 10%. You are permitted to fly only 10 hrs without the boost pump during the whole engine TBO. Once you've reached the 10 hrs limit, you will have to overhaul the engine high pressure pump.

 

Also, in real life I've experienced a hung start when I forgot to put the boost pump on. The Ng did not accelerate past 35%, the point where the secondary fuel nozzles normally kick in and you see a rapid acceleration of Ng. The FS turboprop model start-up happens far too quickly and in a real life C90, the with starter only the engine spools up and stabilizes between 16-20% Ng, depending on battery condition. In FS you can barely reach the required 12%.

Not to mention that the default Carenado soundset starts looping the starter sound shortly after 10%. :(
