ARINC 424 Navigation Database Coding

Introduction

Reference to and use of the “Navigation System Database Standard - ARINC 424”, Path and Termination (P/T) concept has become the “industry norm” for flight path description in Instrument Procedure definition. 

As a result, it is imperative that the procedure designers understand these coding rules in order to provide a “design intent” that reflects those requirements. Also, the course main goal is to familiarize and teach the audience with the FMS logic when “translating” ARINC 424 codes into terminal procedure (SID, STAR and Approaches) flight paths.  

This training provides access to a wide variety of Instrument Flight Procedure coding samples. It optimizes the understanding of PBN (RNAV and RNP) trajectories and allows to predict the expected trajectory of the aircraft. 

The course provides an extended acquaintance with ARINC 424 standard specifications and coding rules.

Objectives

At the end of the course the students will be able to:

• Correctly understand the basic ARINC coding methodologies and history
• Correctly recognize and use the different path and terminators for departure procedures
• Correctly recognize and use the different path and terminators for arrival procedures
• Correctly recognize and use the different path and terminators for approach procedures
• Solve simple exercises about the use and application of path and terminators
• Understand the different impact of path and terminators on an RNAV procedure 

Who Sould Attend

• Primarily
• the course is addressed to procedure designers and airspace planning experts. However
• since PBN concept is a cross-domain model
• the course material is also referring to “end users” like ATCOs and airline pilots
• CAA inspectors involved into IFPD regulatory approval as well as for AIS & Charting experts involved in the State AIP production.

Course Content

• ARINC Standard 424 Introduction
• Meaning of Proposed Coding
• Introduction to NAV System
• Transition Logic for Approach Procedures
• Coding Procedures
• Explanation of FMS, Charting and Simulation of an RNAV Arrival Procedure

Prerequisite

Basic Requirements:

• Have at least 3 years’ experience in an aviation domain such as: Piloting, IFPD, AIS/AIM, Charting, ATC.
• Basic knowledge of Instrument Flight Procedure Design
• Basic knowledge of RNAV navigation is a plus

Additional Requirements:

• Before the beginning of the training, we suggest reviewing the following subjects in order to be ready and receive an efficient training:
• Arithmetic, algebra, geometry and trigonometry
• Basic programming: meaning of while/if/return commands, meaning of algorithm and basic knowledge of at least one programming language

Note:

• The basic requirements are intended to create an efficient class, without having huge differences within the students. This will allow to all of them to properly achieve an acceptable level of preparation.
• Students without basic requirements can anyway apply for the training at their own responsibility.
• Additional requirements are intended to access the training with already a good starting preparation.
