If you just want to see the passengers already in the aircraft, then you can spawn at a parking spot with no ramp/jetway, or simply start the flight directly on the runway, or even in the air. By default, if everything is configured correctly, all the passengers will already be sitting in your aircraft.
Repro steps:
Load DA62 at KEDW on the runway
Check the cabin
Expected: I expect all the passengers will already be sitting in my aircraft.
Actual: Copilot is the only human visible.
Follow the doc link above. it explains how to set up a nav graph. There is a lot of stuff around seatbelts but that is optional.
I don’t have it working, and I can’t get it to work. This bug probably sounds like an end-user complaint, but the problem is that none of the strategies to show pax are working:
career tool
cabin service tool
show-by-default (this topic)
I think there is also a way to ask ATC for boarding, I’ll try that later. But redoing each of these steps only to find it doesn’t work is tedious–having the pax show by default would be one thing that makes this easier and the docs say it should be so.
