Navigation Data
Base (NDB) Working Group
Last Updated:
September 12, 2008
Chairman: Doug White - Northwest Airlines
Goal: The goal of the NDB Working Group is to
assist aircraft operators, manufacturers, regulatory authorities,
and data base suppliers to maximize the operational and economic
benefits of FMS navigation by the exchange of technical information
that improves overall system performance.
Project: Maintain the Navigation System Data Base
Scope: The airborne navigation system reference
data is intended for merging with airborne navigation computer
operational software to produce a navigation data base for use
by such navigation computers onboard aircraft. The scope of
this project is to identify, evaluate, and document the recommended
standards for the preparation of airborne navigation system
reference data for use in the air transport industry. This scope
includes the continued updating of ARINC Specification 424 as
needed to support new navigation procedures
Benefit: There is universal support among
airlines, manufacturers, and regulatory authorities for the
continued updating of ARINC 424. One of the key benefits of
this project is the continued interoperability between new and
older ATS procedures and FMS cockpit implementations. Significant
additional benefits are expected from the reduced separation
standards and the increased availability of user-preferred routing
that will result from NDB Working Group participation in the
development of RNP RNAV procedures.
