INTRODUCTION
    
In recent months, several contributors have provided new, exciting
aircraft and stunts for Electronic Art's "Chuck Yeager's Advanced
Flight Trainer".  (a.k.a.  "Chuck Yeager's Advanced Flight Simulator")
However, with the introduction of jumbo jets like the Boeing 747, it's
pretty hard to get these planes airborne using the 4,700 ft runways
at the main airport.  It's pretty embarassing to have to rumble
around in the fields with your multimillion dollar aircraft, just to
get up enough speed to get it off the ground!  

But, the construction crews have been at work and have just completed
a major airport expansion project, creating Yeager International
Airport (YIA).  YIA provides all the necessary facilities to handle
the wide variety of high performance aircraft now flying in the skies
of Electronic Arts.  

INSTALLATION 

To install Yeager International airport in place of your current main
airport, just copy the MAP00.YIA file in this ARChive over top of your
current MAP00 file.  You may first want to save MAP00 by renaming it
to something like MAP00.SAV; this will allow you to revert back to the
original airport if you choose to do so in the future.  

If you would rather install Yeager International Airport 40 miles
north of the main airport, copy MAP00.YIA over MAP01 (remembering to
first make a backup copy of MAP01.  If you start training flight in
the hangar at the main airport and select "N 40 MI" from the Location
menu, you'll be sitting in the main hangar at Yeager International
Airport.  

FEATURES 

Here's a summary of the improvements made to create Yeager
International Aiport: 

  - Runway 9/27 (the east/west runway) was tripled in length and
    doubled in width.  Its now referred to as Runway 9R/27L and is
    the primary runway at YIA.  

  - An additional east/west Runway was added at the north end of
    Runway 0/360.  Runway 9L/27R is the same length as the primary
    runway, but is half as wide.  

  - Two additional hangars were built to the west of the main hangar.
    The area around the hangars has been paved, creating additional
    tarmac space and taxiways.

  - A north/south taxiway was built at the west end of the airport,
    connecting the two east/west runways with the hangar taxiway.  Two
    fire stations were built at either end of this taxiway.  

  - Two diagonal taxiways were built to the east of the hangar area,
    connecting the two east/west runways with the hangar taxiway.  

  - A new office and administration building was built to the east of
    the hangar area.  

  - The interstate has come through, passing just to the east of the
    airport, and winding around the mountain to the north.  

  - Two north/south jet-blast walls were built at each end of the
    east/west runways.  

  - All this construction required quite a bit of raw material.  This
    was obtained from the open areas to the northeast of the airport.
    Therefore, when you fly in that direction, things may appear a
    little barren, and some of the old familiar landmarks may be
    missing.  

PERFORMANCE 

Because YIA requires a lot of scenery condensed in one area, pilots
may find that the simulation speed is reduced when flying around the
airport, especially with slower computers.  When running on at 8Mhz AT
class machine or greater, performance should still be acceptable for
flying.  

ABOUT THE PROJECT 

Yeager International Airport was created after many hours spent using
DEBUG and other tools to analyze the map files included with AFT.  It
took a while, but I was successful in completely decoding the format
of the sixteen files that make up the AFT world.  As with the
aircraft, races, and stunts, the author's of AFT have provided an
extremely flexible and configurable system that allows modifications
without changes to the actual progam code.  Unlimited variations can
be created, using elements from a predefined library of basic object
shapes.  There are absolute limitations in the total number of
objects, and performance limitations in the number than can be placed
in close proximity.  However, the possibility of creating your own
obstacle courses, airports and race courses is truly exciting.  

YIA is my first attempt to create new scenery for AFT.  All the work
was done using an 8Mhz 80286 Hewlett-Packard Vectra PC with an EGA
display.  Additional flight testing was done on a 12Mhz 80286 HP
Vectra ES/12 PC, a 16Mhz Compaq Deskpro 386 and a 20Mhz 80386 HP
Vectra RS/20 PC.  All development and tests were done with an EGA
display, so I won't guarantee how it looks on other displays.  I used
the original Advanced Flight Simulator, but I've also tried it
successfully with the newer Advanced Flight Trainer.  (The programs
and associated data files are the same; apparently only the name and
logo screens have been changed.) 

If there is sufficent interest (and as time permits) I will document
the complete format of the map files and upload the information to
CompuServe in the near future.  I am also working on a utility that
will be easier to use than DEBUG for creating and editing map files.
