Procedure Coding and Conversion

Aeronautical Guidelines and Standards

Through our certified process and in strict accordance with RTCA DO- 272B and DO-200A guidelines and standards, we code and maintain an Aeronautical Navigation Database, that includes Standard Instrument Approach Procedures (SIAPs), Departure Procedures (DPs) and Standard Terminal Arrival Routes (STARs) in the most current version of Aeronautical Radio Inc. (ARINC 424) data format.

In addition, we have the capability to produce procedures in DAFIF®-like format or to translate DAFIF® data to ARINC 424.

We work with US DoD, FAA, and foreign Aeronautical Information Publications (AIP) in accordance with published 28-day and 56-day Aeronautical Information Regulation and Control (AIRAC) cycles and we encode and maintain our navigation database of RNAV (GPS and RNP), ILS, LOC, VOR, TACAN, NDB, and DP and STAR procedures to ARINC 424 Supplement standards.

Our procedure coding builds our robust aero navigation database in support of simulation, planning, and flight customers.

In our databases coding work, our Aero Analysts process and code Day Forward Procedures, Transitional Procedures, and Gold Standard Procedures from pre-published 8260 series forms and or appropriate government source, and assist in the transition and migration of current ARINC 424 coding to future standards supplements.   We’re actively involved with Industry working group technical discussions and of aeronautical data issues, trends and data format evolution.  We are proactive in the pursuit of emerging innovation data-sharing solutions, such as the ability to encode, validate and transmit in AIXM 5.1 format.

Our work with Terminal Procedures, the National Flight Data Digest (NFDD), CIFP, FAA Form 7100, all versions of FAA Form 8260, the National Airspace Resource (NASR) database, the Digital Terminal Procedure Publication (D-TPP), and COMPSYS21 enables us to code SIAPs, DPs, and STARs as published on the official source documentation.   We have an agile global reach capability that ensures that we code procedures as published in foreign Aeronautical Information Publications (AIP).   We update and maintain U.S. Civil DPs, STARs in NASR and assist the FAA in providing Quality Control (QC) for Civil/Military Instrument Approach Procedures (IAP’s).

AeroNavData’s DAFIF® to ARINC (D2A) conversion services are available to authorized users of the U.S. Government’s Digital Aeronautical Flight Information File (DAFIF®).  Our proprietary software converts the DAFIF® tab-delimited file format to the internationally recognized ARINC 424 format for use in Flight Management Systems (FMS).  Additional features of our Conversion capabilities include:
