IREX Instrument Rating
The IREX exams are available during weekdays by arrangement with Aspeq. Aspeq has examination venues throughout Australia. Sample questions are now available for IREX.
Candidates must achieve not less than 70% to be awarded a provisional pass result. Pilots seeking to convert an overseas instrument rating to the Australian equivalent must achieve a pass in this exam. Guidance to the exam
The IREX is a three and a half hour examination.
A pass in the exam code IREX is one of the requirements for the issue of an Australian instrument rating. The examination is a single paper presented in a multiple-choice question format.
|% Pass Mark:||70%|
|Time Allowed:||3.5 hours|
IREX is based on the aeronautical knowledge requirements specified in CASR Part 61 Manual of Standards (MOS) schedule 3
Instrument approach procedures for an aerodrome may be presented in the DAP chart as: e.g. 1 - ILS RWY 18 or in some cases RWY 18 ILS e.g. 2 - NDB-A and VOR-A or in some cases NDB and VOR Candidates are to ignore these insignificant differences. Preparation of examination papers requires extensive lead time, and therefore it is not possible to take into account information from unscheduled documents, such as NOTAM. However, if a candidate feels that a question has been affected by NOTAM this should be noted in the scribble pad and reported to the Invigilator on completion of the examination.
The AIP SUP is an integral component of the AIP complete and is issued in accordance with a published schedule. Therefore it may be examined.
