(DAICD).
The DAICD is a combination of the
NAVAID Digital Data File, the Digital Chart
Supplement, and the Digital Obstacle File on one
Compact Disk. These three digital products are no
longer sold separately. The files are updated every
56 days and are available by subscription only.
(a) The NAVAID Digital Data File.
This
file contains a current listing of NAVAIDs that are
compatible with the National Airspace System. This
file contains all NAVAIDs including ILS and its
components, in the U.S., Puerto Rico, and the Virgin
Islands plus bordering facilities in Canada, Mexico,
and the Atlantic and Pacific areas.
(b) The Digital Obstacle File.
This file
describes 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.
2. The Coded Instrument Flight Procedures
(CIFP) (ARINC 424 [Ver 13 & 15]).
The CIFP 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
