| Latest version at weflyplanes.com.au | facebook.com/weflyplanes | Back to top Note for December 2 Changes On December 2 2021, there were significant changes to the regulatory structure. The changes included incorporation of many previous CARs, CAOs and some elements of the AIP into new CASR Part 91. Many rules remain unchanged, but can now be found in the newer CASRs as well as the Part 91 Manual of Standards Some new rules were also introduced (such as approach bans). Many rules are largely the same, but with more complicated wording. CASR Part 91 covers General Operating and Flight Rules. CASA have published a Plain English Guide to Part 91 which is available here: casa.gov.au/sites/default/files/2021-08/plain-english-guide-part-91-new-flightoperations-regulations-interactive-version.pdf The terms charter and regular public transport no longer exist within the regulatory framework and has been replaced by air transport. CASR Part 121 covers larger aeroplane air transport (MTOW more than 8,618 kg or more than 9 passenger seats). CASR Part 135 covers smaller aeroplane air transport (MTOW 8,618kg or less and up to 9 passenger seats). CASR Part 138 covers aerial work. For brevity, some of the changes applicable to Part 121 and Part 135 operations (such as aircraft equipment and alternate requirements) have been removed from this update of the Cheat Sheet. They should, however, be included again soon. As the changes are substantial, please treat this document as a work in progress. Be aware that some sections may be incorrect, incomplete or contain inaccurate references. As always, do not use this document for operational purposes.

This is a free resource and we encourage you to share it with others. If you find it useful and wish to contribute, you can donate at weflyplanes.com.au/donate The project began in 2014 for the author’s first Instrument Rating renewal. Since then it has grown and been made available to pilots all across Australia. This resource mostly deals with IFR information in the Australian region. However, other notes have been included where deemed useful. Some sections included in the document have been pasted directly from the original reference with no changes. In cases where the original reference was difficult to interpret or contained superfluous information, attempts have been made to simplify and paraphrase the content. Because of this, the reader should always refer back to the original reference for complete information. This IFR Cheat Sheet has been formatted for printing on A5 paper or for easy reading on a mobile device. We’d love to hear from you with suggestions, improvements, amendments and additions.

Indications by an Aircraft: In Flight (i) during the hours of daylight - by rocking the aircraft's wings; and Note: This signal should not be expected on the base and final legs of the approach. (ii) during the hours of darkness - by flashing on and off twice the aircraft's landing lights or, if not so equipped, by switching on and off twice its navigation lights. On the Ground (i) during the hours of daylight: by waggling the aircraft's ailerons or rudder; and (ii) during the hours of darkness: by flashing on and off twice the aircraft's landing lights or, if not so equipped, by switching on and off twice its navigation lights.

Track to the destination in accordance with flight plan (amended by the latest ATC clearance acknowledged, if applicable). b. Commence descent in accordance with standard operating procedures or flight plan. c. Descend to the initial approach altitude for the most suitable approach aid in accordance with the published procedures. d. Carry out the approach to the prescribed minima. Actions at Minima a. If visual at the minima at an uncontrolled aerodrome, continue to land provided that a safe landing can be accomplished If visual at the minima at a controlled aerodrome continue to land provided that a clearance to land is received via a voice modulated NAVAID and/or light signal from the Tower. b. If not visual at the minima, depart for a suitable alternate aerodrome. c. If insufficient fuel is carried to divert to a suitable alternate, the pilot may hold or carry out additional approaches until visual. d.

In some cases, they do not provide information on the effects of pressure and temperature variation. It is your responsibility to be satisfied that the runway is long enough so you can take off safely (91.410). To account for various levels of pilot competency or aircraft degradation of performance due to age, it is recommended for aeroplanes with landing performance charts which are unfactored, that the following factors are applied to the landing distance required: (a) 1.15 for MTOW of 2,000 kg or less; (b) 1.25 for MTOW of 3,500 kg or greater; and (c) Between 2,000 kg and 3,500 kg, use linear interpolation Landing Distance Required CASR 91.800 – Landing performance Part 91 MOS 25.02 – Landing performance for aeroplanes Part 91 Plain English Guide – Landing performance For small aeroplanes, the AFM landing performances charts are normally unfactored and often do not contain performance information for the effects of runway slope, various surface conditions or wind effect.

Note: Where the first check indicates that an altimeter is unserviceable, the pilot is permitted to conduct a further check at another location on the same airfield; for example, the first on the tarmac and the second at the runway threshold (to determine altimeter serviceability). AIP ENR 1.7 Para 1.2 – IFR Altimeters (Jepp ATC – General Flight Procedures 1.1.2) With an accurate QNH set, the altimeter(s) should read the nominated elevation to within 60FT. If an altimeter has an error in excess of ± 75FT, the altimeter must be considered unserviceable. When two altimeters are required for the category of operation, one of the altimeters must read the nominated elevation to within 60 ft. When the remaining altimeter has an error between 60 ft and 75 ft, flight under the IFR to the first point of landing, where the accuracy of the altimeter can be re-checked, is approved. In the event that the altimeter shows an error in excess of 60 ft on the second check, the altimeter must be considered unserviceable for flight under the IFR. An aircraft fitted with two altimeters but requiring only one for the category of operation may continue to operate under the IFR provided one altimeter reads the nominated elevation to within 60 ft. Should the remaining altimeter have an error in excess of 75 ft that altimeter must be placarded unserviceable and the maintenance release appropriately endorsed. When an aircraft is fitted with only one altimeter and that altimeter has an error between 60 ft and 75 ft, flight under the IFR to the first point of landing, where the accuracy of the altimeter can be re-checked, is approved. In the event that the altimeter shows an error in excess of 60 ft on the second check the altimeter is to be considered unserviceable for flight under the IFR. AIP ENR 1.7 Para 1.3 – VFR Altimeters (Jepp ATC – General Flight Procedures 1.1.3) With an accurate QNH set, a VFR altimeter(s) should read site elevation to within 100FT (110FT at test sites above 3,300FT) to be accepted as serviceable by the pilot. If an aircraft fitted with two VFR altimeters continues to fly with one altimeter reading 100FT (110FT) or more in error, the faulty altimeter must be placarded unserviceable and the error noted in the maintenance release.

The take-off minima are: a) a cloud ceiling of 300 ft; and b) visibility of 2 000 m Part 91 MOS Chapter 15.03 – Take-off minima requirements A pilot in command must not commence a take-off if, at the time of take-off: a) the meteorological conditions are less than the take-off minima for the aircraft; or b) the meteorological conditions that would exist if it were necessary to return to land at the departure aerodrome because of engine failure, are not: (i) at or above the landing minima for any IAP that the pilot in command is able to conduct at the aerodrome; or (ii) such as to allow a visual approach for the return to land.
