Data Link Dissemination (DLD)
About the Project:
The Flight Information Services Data link (FISDL) is a partner ship
between the government and private industry to get affordable, near
real-time weather data to the cockpit of general aviators. In an
agreement signed by private vendors and the FAA it was agreed that
basic weather products would be broadcast for free. The FAA and
industry have defined the following seven weather products as basic
METAR, TAF, SIGMET, Convective SIGMET, AIRMET, PIREP, and Alert
Weather Watches. In an effort to make these products usable in the
cockpit the FAA has sponsored FSL and NCAR to work jointly on
creating decoders for the above weather products. This effort is
called the Data Link Dissemination (DLD) project.
April 2003 Release
The pseudo code, decoder, data dictionary, data flows,
and test suite were delivered to the FISDL vendors in early April 2003.
FSL and NCAR helped the FISDL vendors get a METAR decoder
running in their environment and
Development work will continue pending funding.
