all obstacles of interest to aviation users in the
U.S., with limited coverage of the Pacific, Caribbean,
Canada, and Mexico. The obstacles are assigned
unique numerical identifiers, accuracy codes, and
listed in order of ascending latitude within each state
or area.
4.5.1.3The Digital Aeronautical Chart Supplement
(DACS).The DACS is specifically designed
to provide digital airspace data not otherwise readily
available. The supplement includes a Change Notice
for IAPFIX.dat at the mid−point between revisions.
The Change Notice is available only by free
download from the NACO website.
The DACS individual data files are:
ENHIGH.DAT:High altitude airways (conterminous
U.S.)
ENLOW.DAT: Low altitude airways (conterminous
U.S.)
IAPFIX.DAT: Selected instrument approach procedure
NAVAID and fix data.
MTRFIX.DAT:Military training routes data.
ALHIGH.DAT: Alaska high altitude airways data.
ALLOW.DAT: Alaska low altitude airways data.
PR.DAT: Puerto Rico airways data.
HAWAII.DAT: Hawaii airways data.
BAHAMA.DAT: Bahamas routes data.
OCEANIC.DAT: Oceanic routes data.
STARS.DAT: Standard terminal arrivals data.
DP.DAT: Instrument departure procedures data.
LOPREF.DAT: Preferred low altitude IFR routes
data.
HIPREF.DAT: Preferred high altitude IFR routes
data.
ARF.DAT: Air route radar facilities data.
ASR.DAT: Airport surveillance radar facilities data.
4.5.2The National Flight Database (NFD)
(ARINC 424 [Ver 13 & 15]).The NFD is a basic
digital dataset, modeled to an international standard,
which can be used as a basis to support GPS
navigation. Initial data elements included are: Airport
and Helicopter Records, VHF and NDB Navigation
aids, en route waypoints and airways. Additional data
elements will be added in subsequent releases to
include: departure procedures, standard terminal
arrivals, and GPS/RNAV instrument approach
procedures. The database is updated every 28 days.
The data is available by subscription only and is
distributed on CD−ROM or by ftp download.
4.5.3Sectional Raster Aeronautical Charts
(SRAC).These digital VFR charts are geo−referenced
scanned images of FAA sectional charts.
Additional digital data may easily be overlaid on the
raster image using commonly available Geographic
Information System software. Data such as weather,
temporary flight restrictions, obstacles, or other
geospatial data can be combined with SRAC data to
support a variety of needs. Most SRACs are provided
in two halves, a north side and a south side. The file
resolution is 200 dots per inch and the data is 8−bit
color. The data is provided as a GeoTIFF and
distributed on DVD−R media. The root mean square
error of the transformation will not exceed two pixels.
SRACs DVDs are updated every 28 days and are
available by subscription only.
