So I’m using FBW in MSFS 2024 and using in game ATC (which truth be told is really bad). I plan using navigraph and then copy to simbrief and then import to MCDU
My question really is more related to how interpret and fly those charts. Should I fly the whole STAR and APPR or just the bits that make it to the runway
The real question would be: what does the built-in ATC expect you to do? Without additional information I would program the appropriate NUKRO RNAV transition for your runway/approach, fly direct to NUKRO and then fly the full arrival.
Looking at the more generic question, these long arrivals are designed for traffic management; IRL, it’s likely ATC would, at some point, give you a shortcut via a direct to, but if you’re flying with built-in ATC then it probably won’t do that.
When flying offline or on VATSIM if there is no ATC arriving into such an airport I tend to give myself that kind of shortcut:
