Notes to Airmen and -women:

Welcome to Scenery Disk 12-- as it should have been!

The essential sectors have had upwards of 20 flying hours on
them for debugging. They have been flown on a 286 and 386
with enhanced EGA monitors; no mouse, no joystick. They
have been flown via the Cessna and Piper with satisfactory
results, the Lear Jet with good results, and the Boeing with
limited success.

Even if you don't read TXT files, before using any of these
sector files you ABSOLUTELY MUST change your A&SD config in
two ways: 1) Increase your byte request to 20,000 while
keeping your request for dynamic objects low-- maybe 10; 
and, 2) Have A&SD automatic load active. NOTE: This is on 
Menu #1/J not Menu #5. 

See AUTHORS.TXT for what to do about Menu #5. We HIGHLY 
RECOMMEND that you read or print out AUTHORS.TXT for our
development history, strategy, techniques, and discovered bugs
in FS4 itself or in Scenery Disks 7 and 11.

The only essential files in this ZIP are titled NESCTRnn.SC1
and two (2) NESCTRnn.DY1 files. These must be in the FS4
subdirectory-- as would any scenery disk. Though if disk
space is at a premium, print out the ASCII sectors file and
then choose the areas you'd like to fly. There are several
dummy sectors which we also recommend including since these
will reduce hard disk access as boundaries are crossed. But
these are optional. There is a text file, DMSCTRS.TXT, which
explains the function of a dummy sector and invites creation
of similar .SC1 for your area. That, too, is optional.

These sector files cover every NAVAID in the 13 DECEMBER 1990
AIRPORT/FACILITY DIRECTORY, all the airstrips in CT, MA, ME,
NH, most of NY and NJ, and eastern PA, and VT-- including
for sentimental reasons several private stips. The NAVAIDS
include: VOR, NDB, and ILS as listed. References to other
appropriate charts will line you up for approaches. In fact
we built the sectors from many different kinds of charts from
NOAA or Sporty's. We think you will be pleasantly surprised at
how accurate we have been.

We have added mountains, rivers, roads, and lakes where flyers
would have to take these into consideration. In some cases
we have rebuilt default shorelines, paved over default cities 
and airports either because Sub-Logic was not as accurate in
Default as we were with A&SD or simply because our runways,
lights, color, and placement are better and more accurate.
(Excuse our pride!)

There are some other files that may prove useful depending on
your preferences. There is a simple ASCII text file with the
strips which were built into each sector. There is an ASCII
file of mode coordinates and heading for every strip in each
sector. The first of these is SC1SCTRS.TXT and the other is
MODES.TXT. Either or both can be accessed with LIST.COM or
placed in your word processor and formatted to your liking.
Finally for the truly ambitious: we have included a DBF file
of all the data we used. Though we created and maintained it
with REFLEX2, it has the accepted and standard DBF format. So
it should read into such applications as: PC-FILE, SRINFO,
VPINFO, even PC-TOOLS, and, of course, DB II-III-IV itself.

We do consider material that is original to be ours and should
not be altered without permission. But we offer it as freeware
to our friends on Linx. Questions and comments would truly be
welcome.
