A. GENERAL
^^^^^^^
This scenery is the South Australia (SA) component of the Oz FS5
Scenery Portfolio by The OzPack, an Australian based team of
volunteers who are dedicated to producing high quality FS5 scenery,
covering the entire Australian island-continent, under the freeware
principle. This is being accomplished using a series of pre-planned,
and ongoing state-by-state revisions wherein, with each state's next
revision, more detail is progressively introduced.
The SA scenery has been designed to mesh well with adjoining states'
scenery which comprise the Oz FS5 Scenery Portfolio. There are no
duplications along state borders to "gum up the works".
This revision contains all airports in SA for which
instrument "Departure and Approach Procedures" (DAPS) are published,
plus others which are listed in the Civil Aviation Authority's
"Enroute Flight Supplement - Australia" (ERSA).
The scenery also contains all navaids which FS5 is capable of using,
as well as ATIS and Flight Information Service (FIS) COMs.
All information and physical placements are current as of the 23 Jun
94 edition of ERSA.
Data in the NAV_SA.TXT file may be used to
find your way around. Proper aeronautical charts can be purchased at
or ordered through your local pilot shops. In Australia, these
include the Civil Aviation Authority's VTC series (Visual Terminal
Charts), the ERC Low series (Enroute Charts), the TAC series (Terminal
Area Charts), and the WAC series (World Aeronautical Charts). If your
pilot shop cannot advise which charts to use for SA, or any other part
of Australia, I'll be happy to. Send a message to my address
below.
The large South Australian dry salt lakes have been represented in
this release only as light-grey coloured polygons of very gross detail.
Even though this release has been more concerned with the ocean coastline,
these salt lakes have been so added because of their great size and visual
significance. Fully detailed renditions will be provided in the next release.
Australia is a big country! Distances are deceptive. Make sure you
plan re-fuelling stops. Airports in SA with fuel services are noted
in NAV_SA.TXT.
We endeavour to produce a high quality product which improves
with every edition. You can help us with this task by advising
us of any errors which may be present. We will correct any genuine errors
to the extent that the software allows us.
If you would like us to include a particular feature to enhance your
local area or a particular flight route, such as a private landing strip,
local river etc, we will endeavour to do so in our next edition.
To help us do this you need to provide us with as much of the
following as possible:-
descriptions, diagrams, measurements, Latitude and Longitude, photographs.
The more information you can provide the more likely we will get it
right the first time. The only promise we can make on this matter is
that we will do what we can.

B. SCENERY PROBLEMS
^^^^^^^^^^^^^^^^
FLOATING RUNWAYS
Arguably one of the most frustrating problems in MS FS5 scenery
is the matter of floating runways. FS considers that the surface of
the whole Earth, apart from isolated objects, is at the same hight as the
spot you're vertically over at any point in time. As one moves from
place to place and consequently from one ground-altitude to
another ground-altitude the surface of the whole Earth actually
moves up and down to match the current ground height.
When flying at substantial hight AGL this ground movement can't
be noticed. But when at Ground Level (GL)
or near GL one actually sees the ground moving. All objects, such as
towers, polygon lakes, roads etc. move up and down with the moving ground
so when the ground moves down these objects aren't left in the air.
The one exception to object/ground movement sync are runways. When the
ground moves down below the height of a runway, the runway is left
hanging in the air, a most unnatural sight I'm sure all will agree.
When overflying runways at substantial height AGL the problem can't be seen.
Also when a particular runway is far away from any other runway
the problem can be worked around by making all the surrounding ground
extending out substantial distances from that runway the same height
as that runway. This has the effect that the ground
will carry out its height adjustment movements while planes are still at
a considerable distance away from, and hight above, the target runway.
Note that the same ground movements still happen but can't be perceived.
This work around can't be used
for runways which are both at close proximity to one another and are
at different heights. In these cases when looking from a lower runway to
a nearby higher one the higher one can be seen floating in the air.
We can only hope that MS will solve this bug in due course.
MOUNTAINS
The current version of FS5a scenery doesn't have the ability to render
mountain ranges, sloping ground, high ground, peaks etc in a way that conveys
a good visual sense of changing ground elevations. There are a couple of
options available to us but none are really ideal. We hope to have an
acceptable method for a later release. In the interim be sure to check
your charts to allow sufficient ground clearance in all areas. Otherwise
nearby high ground may make itself known only when you crash into it.
ILS
There is a little known bug in FS5 and FS5a where the ILS glideslopes
in the Southern Hemisphere do not function. However the ILS localisers
work properly and are still worthwhile using.
HORIZON
We have with this release of South Australia partially implemented
a method which substantially improves the horizon problem described in detail
below. We intend to further develop the technique with future releases.
Meanwhile read the problem description below but expect to see it manifest
in the South Australian scenery to a markedly reduced degree.
This version of the scenery contains extensive repair to the otherwise
poorly rendered stock FS5 Australian coastline. Users of this scenery
need to be aware of some FS5 problems which make coastline rendition
less than totally satisfactory. The defect manifests differently
depending whether you have textured ground set on or off.
With Textured Ground ON -
In order to illustrate the coastline problem, establish yourself in
stock FS5 scenery, flying coastal Los Angeles to San Diego, at 5000
feet or above. You should see land on your left, and the Pacific
Ocean on your right. But during your flight, you will see land on the
horizon in front of you, jutting out into the sea. This false land
possibly is the result of the FS5 designers trying to overcome
limitations in the range of land/sea visibility by filling in the
horizon beyond about 35 nm with a poorly rendered green haze - a good
idea, as visibility beyond 35 nm is generally not reliable especially
in the more polluted areas of the world - but sadly this idea is less
than satisfactory in execution.
The result in the map view is less than satisfactory as well. Using
the long range scales, you will see the "haze" as textured green land
on the map's outer border.
Also, with textured ground turned on, and if you're flying, at 5000
feet or above, over land which is predominantly desert (brown terrain
with green patches), you will see a mirage of green terrain on the
horizon. Again, in the map view, using the long range scales, you
will see the "haze" as textured green land on the map's outer border.
Unfortunately, this poorly rendered stock FS5 horizon carries over
into non-stock FS5 scenery as well, including OzPack's scenery for
Australia.
So please be advised. It is not possible to navigate by reference to
bays, capes, and other coastal landmarks in view 1, 2, or in map view
beyond a ground range of about 35 nm.
With Textured Ground OFF -
Unfortunately, there are other unsatisfactory phenomena with textured
ground turned off. Instead of the putrid green haze on the horizon,
there is "the black void". Beyond about 35 nm, land mass is rendered
as simply a black space in the two views and the map.

C. CREDITS
^^^^^^^
Many thanks to the other OzPack members - John Blackie,
Bryan Fripp, Ron McKeirnan, Tom Monnone and Adam Szofran,
- for providing advice, cooperation, encouragement, co-ordination
and technical support.
A portion of the scenery was compiled using BGLGEN.EXE developed by
Enno Borgsteede. BGLGEN was developed with help from Maurizio Gavioli
and associates. Many thanks to Enno, Maurizio and associates.
