Default Scenery Fixes for Two Massive Holes and Four Other
This scenery patch corrects six problems in the Microsoft
Flight Simulator 2004 default scenery. Specifically, in
FS2004, Millwood Lake which is situated in Arkansas has
an enormous error in which half the surface of the lake
is 15,000 ft below sea level. The next error is similar
to the first error and is situated at Stockton Lake in west-central
Missouri at a depth of 11,500 ft below sea level. The next
glitch is near Memphis, Tennessee where an airport flatten
is causing a hill (or cliff if using high resolution mesh
terrain) where there is no airport. The next problem is
in Alaska at Girdwood airport (AQY) where the adjacent river
is placed too high making cliffs right next to the airport.
Another glitch at Davis airport (KMKO) in Muskogee, Oklahoma
exists where the runways are situated over large sinkholes
and the runways themselves are floating. The final glitch
is in Guiana, South America where a 100,000+ ft chasm and
a 60,000 ft spire exist along a river. These files correct
these errors and reproduce the lakes at their proper elevations,
remove the big hill near Memphis, fix the floating runways
at Davis airport, lower the elevation of the river at Girdwood
airport, and remove the 100,000+/60,000 ft chasm/spire.

Detailed overview of what this patch fixes and how
There are a total of seven files affected by this scenery
fix. They are FL923190.bgl HP922190.bgl HP922180.bgl HP923180.bgl
FL922190.bgl HP908100.bgl HP931290.bgl. most of which are
located in the <FS2004 path>/Scenery/Namc/Scenery folder.
HP908100.bgl resides in the <FS2004 path>/Scenery/Namw/Scenery
folder and HP931290.bgl resides in the <FS2004 path>/Scenery/Same/Scenery
folder. The setup program renames the original files so
that they are ********.original. (That is to say that they
have the same file name but with an "original" file extension).
The setup then copies some of the corrected files from the
setup folder to the <FS2004 path>/Scenery/Namc/Scenery folder.
The other corrected files go to the <FS2004 path>/Scenery/Namw/Scenery
folder and the <FS2004 path>/Scenery/Same/Scenery folder
respectively. The setup program comes with a un-installation
utility that essentially does the reverse of the setup program.
It deletes the modified BGL files then renames all the original
files back to BGLs.
The only change in the HP922190.bgl file is of Millwood
Lake whereas the lakes elevation in the file was incorrectly
set to about 4000 meters below sea level. The elevation
has been corrected to about 83 meters about sea level.
Correcting the Stockton Lake scenery error required changing
the elevation of the lake in two scenery files -- HP923180.bgl
and HP922180.bgl. The rest of the data in these two files
are original default scenery.
The Davis airport error actually has two flattens. Normally,
only one flatten is required to define the elevation of
an airport. Davis airport is rather unique in the default
scenery since it’s the only one that I know of that actually
requires two flattens. I found this out when I removed one
of the flattens from the FL922190.bgl file and noticed all
kinds of problems at the airport. I then put it back in
but at the same height as the other flatten and thus, the
error of the floating runways vanished.
Girdwood airport in Alaska is similar in nature to the giant
holes errors at Stockton Lake and Millwood Lake and simply
required changing the elevation of the river in the HP908100.bgl
file from 166 meters to 45 meters above sea level.
The only change in the FL923190.bgl file is of a small region
near MS65 where an apparent airport flatten cell was used
but there was no airport at the location. The elevation
of the flatten was causing a rather large hill that was
visible from downtown Memphis, Tennessee. As there are no
hills of any real size near Memphis, Tennessee, this was
obviously a scenery error which had to be fixed by simply
removing the airport flatten cell from the scenery file.
The final fix in Guiana, South America was due to elevation
points in the river data that were too close to each other
and causing large effects because of it. I simply removed
some unnecessary elevation points in the HP931290.bgl file
that were too closely bunched together.
Everything else contained within the above mentioned files
is default scenery from Microsoft. No changes are made to
any other file or program via this setup utility.
Simply run the included setup.exe program. Installation
is completely automatic!
