LNM doesn’t see that as a seabase. Or rather no actual water starts:
LUDD seems to be the only one that does have a water start. W55 and 0W0 don’t:
LUDD also appears in italics, which makes me believe its custom in some way.
All the non-italicised seabases don’t, which makes me think this is an issue with Blackshark AI, and its creation of these airports as it has no way of identifying a ramp start. If you have an image of a land based airport you can see where the parking spots are, typically, and the AI can pick these out. It can’t see those on water as they don’t really exist, so it makes sense to me that they would have to be hand tweaked by someone.
Just firing up the sim to see where LUDD comes from.
Here is Port Orchard (4WA9):
And in LNM:
And in the sim:
No hand tweaking, just AI, and it was able to see 4 spots plus the top one which has been designated fuel.
By comparison, here is Lake Union Dock (LUDD):
The AI has literally no clue where to place a ramp start.
So this was tweaked to add ramp start 0A, highlighted:
I agree with you that his wording was…inaccurate. It can be done, but the airport data has to be tweaked to support it.
