Hi again,
there is a general issue in the MSFS with this airport. ROAH is outdated in MSFS comparing the real-world.
When you look into the MSFS, you only see two runways 18L/36R:
Comparing the real-world, ROAH has four runways 18L/36R and 18R/36L:
The MSFS disables existing terminal procedures which can´t be assigned to a specific runway - not only for the specific runway, the MSFS disables all terminal procedures then. And that has nothing todo with any update or any aircrafts - it´s the core logic in the sim.
No SIDs available:
The same for the STARs but here, there are a few available - all STARs which are valid for ALL runways. Specific STARs to a specific runway are also disabled thru the MSFS
That´s exactly the reason why you only see LAVON, SCUBA and LAFTY because all other STARs are runway specific to 18LR/36LR and these STARs will be suppressed by the MSFS.
… now, when you use a possible available 3rd party scenery for ROAH which includes all runways, you will immediately see all SIDs and STARs in the WorldMap + also in all aircrafts (ie. WT787).
Here I have installed a freeware scenery from flightsim.to - all runways are available:
SIDs:
STARs:
… and also in B787 FMC:
You see, I have only added the 3rd party scenery, which includes all runways as in the real-world - without any additional installation of data and all terminal procedures are available immediately.
Again, this is a MSFS limitation and there are a lot of outdated airports which missing runways or wrong runway-idents comparing the real-world. In such cases, terminal procedures will be disabled by the sim but you still have it in the data, when you install as an example a 3rd party scenery.
Hope that helps,
Richard
