ARINC Data for UK Royal Air Force

Overview

DAFIF® is a unique format suitable for mission planning and limited flight management system (FMS) applications.  To make DAFIF® useful in the majority of aircraft FMS’s No1 Aeronautical Information Documents Unit (No 1 AIDU) must convert it to the international Aeronautical Radio Inc. (ARINC) 424 format.  Critical to this conversion process is an accurate mapping of aeronautical data from DAFIF® to ARINC coupled with software that performs consistently without error.   No 1 AIDU provides valuable geospatial data to all aspects of HM Armed Forces and is charged with the production of all aspects of aeronautical data, including arrival, departure, approach, and enroute data.

Challenge

In addition to their domestic mission, No 1 AIDU has an international mission of support to the U.S. National Geospatial-Intelligence Agency (NGA) sponsored Quintipartite Committee.  As a Quint member, No 1 AIDU is charged with maintaining the aeronautical navigation dataset for Western Europe.    No 1 AIDU uses the DAFIF® as well as other foreign Aeronautical Information Publications (AIP) to maintain its GOTHIC database.  Although DAFIF® is a worldwide dataset, it only contains terminal procedures specifically requested by the U.S. military and therefore, does not completely address the RAF’s mission requirements.

Solution

AeroNavData solutions were used to convert DAFIF® for Flight Management System use on 6 RAF airframes.   AeroNavData coded 3000 European Terminal Procedures and delivered ARINC data directly to the Royal Air Force (RAF) No 1 AIDU.  We delivered this data in a format compatible with NGA’s Digital Aeronautical Flight Information File (DAFIF®) where it was merged with AIDU’s GOTHIC database.  Our D2A Conversion software was then used to convert the merged procedures into a format that could be loaded directly into the Flight Management Systems of six RAF airframes.

Results

AeroNavData’s years of DAFIF® and ARINC domain expertise enabled us to support AIDU’s mission and assist them in the fulfillment of their ‘Quint’ obligations by expanding the size and scope of its GOTHIC aeronautical database.
