IREX courses change

As a result of the recent changes to the Civil Aviation Safety Regulations 1998 Part 61, there are going to be some changes to the content, and therefore the exams for the IREX as of September 2014.

As yet, the actual changes to the IREX exam have not been made too clear, however the new IREX syllabus does have some interesting new additions to consider. The old syllabus was in Civil Aviation Order 40.2.1. The new syllabus is in Volume 3 of the Part 61 Manual of Standards.

Anyone who is to sit the IREX exam in the future needs to be familiar with the new changes and how they will affect their study preparation. At the date of this article, Aviation Theory Virtual Classroom (ATVC)  is in the process of updating its course material and exams to reflect the new changes.

Very little has been said regarding the changes, but the significant changes, as identified by ATVC include the following:

  • Instrument rating endorsements have had some changes in their naming. These now fall into 2 main categories: 
    • 2D Approaches replace what used to be called 'non-precision approaches (including the old NDB, VOR, Localiser, DME/GNSS arrivals, and GNSS approaches.
    • 3D Approaches replace what used to be called 'precision approaches' (including the ILS and the new GLS approaches)
  • Approaches are now also identified by one of the following descriptors:
    • 'azimuth guidance procedures' using bearing information (effectively like the old NDB approach or by an RMI)
    • 'course  deviation indicator procedures' which make use of a CDI (such as used by the VOR, GPS, localser and glidepath)
  • IFR recency requirements have changed compared to what was listed in CAO 40.2.1 section 11
    • The new requirements are listed in CASR 1998 Part 61.M
    • This will change a section of the syllabus that was fairly heavily examined in the past
  • The syllabus now has 3 new sections that were previously not in the syllabus. It will be interesting to see how some of these sections are examined, as some aspects of the syllabus seem to be designed to 'future proof' the syllabus. By this, it is meant that some technologies are not yet available fully in Australia. New areas to be examined include:
    • Performance Based Navigation (PBN)
    • Required Navigation Performance (RNP) specifications that include new types of GNSS based approaches including those with vertical guidance
    • Reduced Vertical Separation Minima (RVSM) that apply to aircraft flying between FL290 and FL410
    • Human Factors for instrument flying
