Hi Paul:
I am inclined to think Dick is likely to explain your options for finding the MSFS sub-folder for your airport of interest pending your reply.
We do need a workaround (since months ago) for ADE to find/load non-Deluxe / non-Premium airports (aka "generic airports") in MSFS.
Whereas ADE Alpha-21 HF-5 has updated its internal database of airport ICAO's, AFAIK, it is not yet able to find / load "generic airports".
MSFS'
MS-Store version (mine is the Deluxe / Premium version)
current path for ADE to use in finding / loading
FHAW:
[MSFS-2020_Packages install path]\Official\OneStore\fs-base-genericairports\scenery\0504\
APX44340.bgl.
(Hmmm ...might this path to MSFS "generic" airports now be a 'moving target' to slow down freeware airport modders / developers ?)
FYI: This path is determined by via an existing FSX or P3D installation:
Google search this query string: "wiki Ascension Island airport ICAO"
Click this link in the query results:
https://en.wikipedia.org/wiki/RAF_Ascension_Island
At the top right of that wiki page, click on:
On the the top right of the resulting GeoHack page for that wiki, copy: the 'decimal' Geographic Coordinates into Windows' clipboard
In the table below on that same GeoHack page,
click on: Google Maps > Satellite, then zoom out to see that ICAO's 'world area'
Browse to:
https://www.prepar3d.com/SDKv5/sdk/world/terrain/terrain_overview.html#Base File Information
After determining the FS 'world' Area ID number (
# 0504 for
FHAW), load FSX or P3D SDK
TMFviewer, then
browse to:
[FSX or P3D install path]\Scenery\0504\
Load:
dem0504.bgl into TMFViewer,
then:
TMFViewer Menu > Jump > Lat-Long... > paste / edit
FHAW decimal coordinates into Latitude and Longitude fields > click {OK] button
Zoom in until
File # 4434 appears (
and no longer changes if you move the mouse cursor); this confirms the FS Area file # of
FHAW
NOTE: MSFS does not seem to have a CVX vector Airport Boundary Polygon for
FHAW, so you may need to make your own flatten.
To see the FSX / P3D airport flatten, load this file into FSX / P3D SDK TMFViewer as well:
[FSX or P3D install path]\Scenery\0504\
CVX44340.bgl
In
ADE Alpha 21, HF-5 after filling in the initial required MSFS data,
browse to load
FHAW from:
[MSFS-2020_Packages install path]\Official\OneStore\fs-base-genericairports\scenery\0504\
APX44340.bgl.
I hope this helps with this- and other future- projects ...until Jon (finally) issues a HotFix or new Alpha of ADE 2020 for MSFS.
PS: Perhaps Dick knows a MSFS "system" file we could instead load into FS2Kx / P3D SDK TMFViewer to do this via MSFS' folder chains ?
