A.  GENERAL
    ^^^^^^^
This scenery is the Tasmainia (TAS) 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 TAS 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 TAS 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).  Included are airports 
on the off-shore Bass Straight islands.  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 and amendment 43 to DAPS EAST, effective 18 Aug 94.

Data in the NAV_TAS.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 TAS, or any other part 
of Australia, I'll be happy to.  Send a message to my address
below.

Tasmainia contains a lot of high areas, ( 4000 + feet ). The current 
versions of FS5a scenery doesn't have the ability to render 
mountain ranges, sloping ground, peaks etc in a way that conveys 
a good sense of changing ground elevations. I hope to produce better soon.  
Meanwhile I have coloured the higher areas with a browner coloured surface
so that in the interim you will at least have some way of recognising
an approaching high area. Be sure to check your charts to allow sufficient 
ground clearance in all areas.
  
Australia is a big country!  Distances are deceptive.  Make sure you 
plan re-fuelling stops.  Airports in TAS with simulated fuel are noted 
in NAV_TAS.TXT. 

B.  SCENERY PROBLEMS
    ^^^^^^^^^^^^^^^^
ILS
There is a little known bug in FS5 and FS5a ILS *glideslopes*.  This 
bug is found only in southern hemisphere ILSs and affects ILSs in all 
course directions. There are two ILSs in TAS.  Both gligeslopes 
do not function in the current versions of FS5a.  However the 
ILS *localizers* seem to work properly.

HORIZON
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.

    ^^^^^^^
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.
