A definite focus on Meteorology and Alternates is recommended. You need to be an expert on alternate requirements.
Always look things up never go off memory as CASA loves to find a little quirk to trick you e.g. VOR with reduced ranges. Sometimes the final words of a sentence give the entire sentence or paragraph a different meaning. CASA loves those little tricks, to find and catch skim readers and people who break rules by jumping to assumptions instead of checking the detail.
Familiarise yourself with the front and back sections of ERSA and Definitions in AIP Gen 2.2. Also know how to find holding times at major airports from ERSA.
Know AIRES frequencies and what they provide.
ICE ICE ICE. Given temp, altitude and condition you absolutely must know what ICE risk is present.
ROD and ROC. Given % climb or descent you should be able to calculate any question with speed given to arrive at fpm.
CASA loves to play tricks in this exam. Eg. You are flying into X airport using VOR navigation. What is the ILS requirement for runway 30? or You are flying into X airport RWY 03 using GNSS navigation. What is the RNAV requirement for runway 21?
Weather, weather, weather. The exam has a huge focus on operational requirements or issues with weather.
This is generally not a time pressure exam. You have time to double check and check details. Make notes on your paper of the pages you found info for various questions so that you can go back and double check or recheck finer details. Use all your allocated time.
The order of questions doesn’t really matter. Do them in any order.
People who fail this exam, do so because they rush and misread trick questions or they fail to know ICE, ROD or ROC, alternates and weather. Most can find what they need in the charts or rules.
Yes your charts need to be up to date. Pay attention to TAC RVR and DA. Almost every question worth more than 1 mark has more than one question, so read it very carefully.
If you get questions with fuel requirements, check and double check ERSA for extra holding fuel, due to traffic.
Fuel Policy – Fuel reserves are in accordance with CASR Part 91 Table 19.02 for aeroplanes ≤5700kg under IFR or CASR Part 135 MOS Chapter 7.
Each question will clearly state either Part91 or Part 135.
Part 91 MOS states final reserve fuel is at holding rate, however read below:
However, the CASA website on the PIFR and IREX exams pages states:
These two underlined sections from the PIFR and IREX pages, contradict each other. So we wrote to CASA seeking clarification.
CASA’s response is:
You are quite correct with your understanding that CAAP 234-1(2.1) specifies a holding rate, based on ISA conditions at 1500’. In both PIFR and IREX, you don’t actually calculate a fuel burn (i.e. no fuel flow is specified) whether in Kgs, Litres or gallons. You are simply required to determine the number of minutes of fuel required, e.g. for IREX given a flight time of 77 minutes for a CHTR flight, and a forecast (which may require some holding OR the nomination of an alternate). You would then simply add up the 77 minutes trip fuel with the required minutes of reserves (and if a diversion was required, the time for the diversion would be specified in the question).
As you are not working with fuel flows, there is no conflict between the CAAP and the exam fuel policy requirements.

In law exams or law parts of exams it is extremely unlikely that you will be given any law references.
We sometimes include them in the questions to help candidates towards the beginning of their study find things.
A huge part of law is you knowing how to find things quickly. Read and check the legislation and DO NOT rely on memory for answers.
PPE’s Ultimate Law Guide PDF, will become the ultimate study buddy, for locating the laws and ticking off when you know them.

AC 91-15v1.1 Guidelines for aircraft fuel requirements
To Categorise flight operations you have to dig through the CASR dictionary / definitions and the following pages. To my knowledge there is no one location that clearly sums them all up in the detail you are after for each.
https://www.casa.gov.au/search-centre/rules/part-91-casr-general-operating-and-flight-rules
Part 91 applies to all aviation operations except drones.
There are additional rules for pilots operating under an Air Operator’s Certificate (AOC) or other certificate, or those conducting defined activities such as aerial work, aerial application and some recreational aviation activities. These rules are in other CASR Parts and may add to or turn off some Part 91 requirements – either completely or partially.
—————————————-
.
Part 121 generally applies to air transport operations in aeroplanes with a seating capacity of more than 9 seats, or a maximum take-off weight (MTOW) of more than 8,618 kg.
Subpart 121.Z applies to air transport operations in single-engine aeroplanes with a seating capacity of more than 9 seats and a MTOW of 8,618 kg or less.
All operators and pilots also need to comply with Part 91 – General operating and flight rules, noting that Part 121 may add to or turn off some Part 91 requirements – either completely or partially.
—————————————-
Part 135 of CASR applies to air transport operations in aeroplanes with a maximum seating capacity of nine and a maximum take-off weight (MTOW) of 8,618 kg or less.
Subpart 121.Z applies if you are operating single-engine aeroplanes with a seating capacity of more than 9 seats. However, you must comply with the majority of Part 135.
Some operators may be able to operate an aeroplane with up to 13 seats if they are already conducting these operations and meet the requirements.
All operators and pilots also need to comply with Part 91 of CASR General operating and flight rules, noting that Part 135 may add to or turn off some Part 91 requirements – either completely or partially.
—————————————-
Part 133 applies to air transport operations in helicopters, gyroplanes or powered lift aircraft.
All operators and pilots also need to comply with Part 91 of CASR General operating and flight rules, noting that Part 133 may add to or turn off some Part 91 requirements – either completely or partially.
—————————————-
https://www.casa.gov.au/search-centre/rules/part-138-casr-aerial-work-operations
All operators and pilots also need to comply with Part 91 of CASR General operating and flight rules, noting that Part 138 may add to or turn off some Part 91 requirements – either completely or partially.
Aeroplane operators may choose whether to conduct dispensing operations under Part 138 or Part 137 of CASR Aerial application operations. Requirements for the dropping or releasing of any substance overlap for Part 138 and Part 137. Note: Part 137 only applies to aeroplanes.

This is a one page PDF to get you all the basics in one place.
Calculation of ETP and Asymmetric ETP are for CPL upwards only.
Note only very basic ETP would be in CNAV. Any hard ETP or PNR will be in CFPA exams only. At one stage CASA slipped a few into CNAV, but we believe that error has been rectified.
