The only things that can be overridden this way, TTBOMK, are apt.dat,
nav.dat and fix.dat contents, using NavData/{apt,nav,fix} subfolders
located inside components of $FG_SCENERY. The announcement for the nav
and fix feature is at [1] (that was Szymon Acedański's work).

Remember that there are also *.ils.xml files in TerraSync. AFAIR, they
can override part of the data obtained from nav.dat files. This was
discussed at [2] concerning VTSP (Phuket).

You'll find a few technical details in that thread, but concerning
alignLocaliserWithRunway(), be aware that it was removed in FG commit
889c1bf0cb28[3] after that discussion. Pity that the SourceForge
mailing list archive appears to be unable to display any page with
number >= 2 in a thread archive...
