I’m not a real pilot and not an expert for the C408. But I think the EFB Checklist is not complete.
Espaecially the enginge start seem to miss several items.
To start the engine it’s nessesary to activate the Fuel Boost.(?)
Has anybody the original POH for this aircraft?
Over in the other thread there’s been some discussion that the systems modeling is wildly incomplete, and the checklist is also wrong/incomplete for the simulation, and nothing matches the real-world plane.
