- -----Introduction-----
-
- This file is intended to give you basic information on the scenery files
- contained in the archive, along with other vital information, such as
- registration costs and technical explanations of the files themselves. In
- addition to this file, there is a README.2ND file which contains information
- on the specific scenery files contained in the archive. This second file
- will give information about scenery coverage, instrument approaches, and
- other scenery-related items. In order to fully enjoy the enclosed scenery,
- you should print out the README.2ND so that you have a listing of all this
- data.
-
-
- -----Using the Scenery Files-----
-
- Obviously, in order to use these scenery files, you must have a Microsoft
- Flight Simulator Program *and* the Microsoft Aircraft and Scenery Designer
- (abbreviated A&SD) files. The archived scenery files were created by and are
- for use with the A&SD ONLY. They ARE NOT true "scenery disks", and can not be
- used as such (ie - if you try to load them from menu 5, option 2, as scenery
- disks, IT WON'T WORK). You MUST have the AS&D, available commercially from
- your local software retailer/wholesaler/fence/etc... =)
-
-
- -----Registration-----
-
- This archive is shareware If you like what you see, and wish to encourage
- more scenery development, then please register your copy by sending $5.00 to my
- permanent address:
-
- John Mechalas
- 2830 Townway Rd.
- Danville, IL
- 61832
-
- Below are a few reasons why you should register this product:
-
- 1) Upon receipt of your registration fee, you will be sent copies of
- published Instrument Approach Procedures for the various ILS approaches
- supported by the scenery files. These are very helpful if you want
- to make instrument landings, particularly in adverse weather.
- Some of you are probably pilots and already have access to these
- approach plates, so therefore this isn't much of an incentive for you.
-
- 2) It took a long time to create a lot of these files, and even though I
- didn't really ever expect to make any money off this, it sure would be
- neat.
-
- 3) You'll feel a lot better about yourself afterwards, and will go to
- sleep knowing that you have done the right thing.

-
- -----Comments and Suggestions-----
-
- If you have any constructive comments or suggestions, then you can either
- mail me at my address given above, or contact me through my net address below:
-
- mechalas@gn.ecn.purdue.edu
-
- This address will be valid until the summer of '94, upon which I will
- graduate and will never see the account again.
- EVEN IF YOU DON'T WANT TO REGISTER THIS PACKAGE, PLEASE FEEL FREE TO SEND
- ME COMMENTS, ANYWAY. I can really use your input and opinions, and it would
- also give me an idea as to how many people are really using these files.
-
-
- -----Technical Information-----
-
- My main reasons for purchasing the A&SD and creating these scenery files
- were due to the limitations of the actualy scenery disk put out by subLOGIC
- and Mallard software, and especially the default scenery that comes with the
- Flight SImulator package. Although the scenery disks themselves contain a lot
- of scenery data, particularly the newest subLOGIC collections, the wide
- coverage of the scenery disks makes it impossible to make dense, detailed
- scenery information of particular locations. In particular, ILS approaches
- at major airports are missing, simply because of scenery file limitations.
- Also, current scenery disks do not support dynamic scenery, one of the neatest
- features of the FS 4.0 program, so in order to view it you must use the
- default scenery, which is terribly sparse, and not very accurately "placed"
- on the continent.
- Through the use of the A&SD, it is possible to define tight, compact scenery
- regions that allow for highly detailed scenery. I primarily used the program
- to generate highly localized scenery files, so that I could add instrument
- approaches, approach lighting, and dynamic scenery on an airport-by-airport
- basis. Although this takes up more disk space by forcing the creation of
- several scenery files instead of one wide-spread one, more detail is possible.
-
- * Dynamic Scenery - Dynamic scenery is a real hog on disk space. Only a
- couple complicated patterns are enough to completely
- fill your available bytes, and allocating more memory
- for these files is not only ineffective, but also
- impractical if you are using other applications, such
- as Mallard Software's Sound and Graphics Upgrade**.
-
- As a result, in order to have dynamic scenery at each
- airport region you detail, it is almost necessary to
- create a seperate file for each airport. In order
- to auto-load this scenery, I also create a seperate
- static-scenery file for each airport, which allows me
- to further detail those airports as an added benefit.
-
- * Static Scenery - Since the Flight Simulator coordinate system is not
- very accurate (hence subLOGIC's change to a new ref-
- erence system in their ATP*** package), exact placement
- of runways was not always possible. Airports were,
- however, detailed as accurately as possible based on
- the information I had at hand. In most cases, build-
- ings were deliberately oversized in height because the
- scenery designer tends to not display shorter objects
- until they are very *very* close to your aircraft. By
- making the buildings taller, they can be seen from a
- greater distance.
-
- City buildings and towers and other scenic objects were
- placed more for aesthetics than accuracy, so in most
- cases buildings and the like were just semi-randomly
- placed in small clusters. Although this doesn't give
- a very accurate rendition of the cities, as mentioned
- above, it does give the cities the "look and feel".
-
- * ILS Approaches - All ILS approaches were taken from the Government
- Publications of US Terminal Procedures. In some cases,
- an ILS frequency is used for opposing ends or parallel
- runways. Since A&SD can not be used to differentiate
- between two beacons with identical frequencies, in such
- cases I changed one of the offending nav-aids to a
- higher or lower frequency. These changes are pointed
- out in the README.2ND file, where necessary.
-
- Placement of VOR beacons is not always exact due to
- the FS coordinate system's limitations and minor errors
- in the scenery disks themselves. As such, the NOAA
- approach plates don't agree perfectly with the ILS
- approaches in my scenery files, but they are very close
- and can still be used for accurate instrument landing.
- As mentioned in the "Registration" section above, those
- of you who send in the $5 registration fee will be
- given copies of the appropriate approach plates used in
- defining the instrument approaches for your particular
- scenery file (be sure to let me know which files you
- are registering, so that I can send you the correct
- ones).
-
- * ATIS Centers - Through the use of the Scenery Enhancement Editor****,
- available from Mallard Software, it was possible to
- create ATIS centers for selected airports. This is of
- particular importance in the new California scenery
- collection from subLOGIC that does not include any ATIS
- centers.
-
-
- ----- Scenery Design Limitations -----
-
- 1) One of the best features of the A&SD is the ability to "draw" detailed
- runways. Unfortunately, runways tend to bog down the simulator more than any
- other scenery object. Complicated runways with touchdown zones, threshold
- markers, dashes, numbers, and other neat detailing are a real hog on speed, and
- if you have a 386SX system or lower, you may have to reduce some of the detail
- in my runways (particularly at large airports like O'Hare) in order to keep
- a reasonable redraw-rate during landing and takeoff.
- 2) Buildings that are placed too close together sometimes fool the scenery
- drawing. Every now and then, you might see one building that is drawn in front
- of another building, when it is actually behind it. This is particularly
- evident at airport terminals, where I put several buildings together in order
- to form one large, complex shape.
- 3) A&SD objects are drawn after Scenery Disk objects, and for some reason,
- there is an strange side effect when using A&SD with the scenery disks. The
- program apparently can not or does not check object distance for scenery disks,
- because A&SD objects that are *behind* a scenery disk object are drawn *in
- front* of the scenery disk object. This means that you may see buildings
- plastered over a mountain or another building that is part of the scenery disk.
- For some reason, this doesn't happen with the default FS4 scenery. Usually I
- corrected the problem by drawing a building on top of the scenery disk
- building, but sometimes this was not possible.
-
-
- ----- Scenery Enhancements -----
-
- Through the use of Mallard Software's Scenery Enhancement Editor, it
- was possible to overcome several of the limitations of the A&SD. It is
- now possible to change the appearance of objects at night, create strings
- of lights, ATIS and COMM messages, and custom-made library objects. This
- archive of scenery files contains all of these new features.
- IT IS NOT NECESSARY TO HAVE THE SCENERY ENHANCEMENT EDITOR TO USE THESE
- FILES. The enhaced files are .SC1 files just like any other scenery file,
- and can be used with A&SD. The Enhancement Editor merely edits these files
- to allow for greater flexibility, and is not required (or used) for scenery
- display.
-
-
- ----- Concluding Remarks -----
-
- I hope you enjoy the scenery files, and please feel free to send me any
- constructive comments to the address I gave above. And don't forget to read
- the README.2ND file before flying. It contains important information on the
- files contained in this archive.
- Happy landings. :)
