7.4 An FCM is considered to remain in his or her state of acclimatisation (whether acclimatised to a particular location, or in an unknown state of acclimatisation) until he or she has had:
(a) an adaptation period in a location (the adaptation location) in accordance with Table 7.1 in this subsection; or
(b) an adaptation period that is:
(i) in a location other than home base; and
(ii) in accordance with subparagraph (a); and
(iii) reduced by 12 hours for each previous off-duty period that:
(A) immediately preceded the adaptation period; and
(B) was taken at an off-duty location which differs in local time by less than 2 hours from the adaptation location; and
(C) included an off-duty location local night.
7.5 In applying Table 7.1 to arrive at an adaptation period for paragraph 7.4:
(a) determine the time zone displacement between:
(i) the location where the FCM was last acclimatised (the original location); and
(ii) each location where an FDP or off-duty period was commenced since last acclimatised (later locations); and
(b) then choose the time zone displacement between the original location and whichever of the later locations gives the greatest time zone displacement; and
(c) then choose the time zone change in the Table that corresponds to the greatest time zone displacement; and
(d) then choose the direction (west or east) in which the FCM travelled and in which, therefore, the greatest time zone displacement occurred under subparagraph (b); and
(e) then choose the number of hours west or east (as the case requires) that corresponds to the time zone change chosen under subparagraph (c).

11 Part 137 operations
11.1 Despite any other provision of this Order, this subsection takes effect on 2 September 2019.
11.2 In this subsection:
relevant operation means an aerial application operation in an aeroplane under Part 137 of CASR.
Note Subsection 11 has no application to aerial application operations in a helicopter.
11.3 Except for this subsection, paragraph 16.1 and any relevant definitions in subsection 5, this CAO does not apply to:
(a) an AOC holder engaged in a relevant operation;
(b) an FCM employed by, and undertaking duties for, the AOC holder mentioned in subparagraph (a).
11.4 It is a condition on the AOC of an AOC holder mentioned in subparagraph 11.3 (a) that the holder must comply with Subpart 137.Q of CASR.
Note Such AOC holders are bound by Subpart 137.Q of CASR and there are penalties under Subpart 137.Q for failure to comply.
11.5 It is a condition on the flight crew licence of an FCM mentioned in subparagraph 11.3 (b) that the FCM must comply with Subpart 137.Q of CASR.
Note Such FCMs are bound by Subpart 137.Q of CASR and there are penalties under Subpart 137.Q for failure to comply.
11.6 Subject to paragraph 11.7, before an FCM conducts a relevant operation for an AOC holder, the holder must be satisfied that the FCM has received awareness material, or training, in managing the fatigue-related risks relevant to his or her duties as an FCM.
11.7 Paragraph 11.6 does not apply until 1 July 2020 to an AOC holder for a relevant operation if the holder held an AOC for the relevant operation immediately before 30 April 2013.
12 Private operations
12.1 Subject to paragraph 12.3, this CAO does not apply to an AOC holder when conducting private operations.
12.2 Subject to the condition mentioned in paragraph 16.1, and paragraph 12.3, this CAO does not apply to an FCM when conducting private operations.
Note The condition under paragraph 16.1 applies to FCMs whether or not they are employed by an AOC holder. Paragraph 16.1, therefore, applies to FCMs engaged in private operations as well as FCMs engaged in operations under an AOC. Guidance on the assessment of individual cognitive and physical fitness is contained in CAAP 48‑01. CASA recommends that FCMs engaged in private operations consider this guidance in determining self-prescribed limits.
12.3 Despite paragraphs 12.1 and 12.2, if an FCM performs duty by conducting a private operation (a private flight) during an FDP that involves a flight that is not a private operation (a non-private flight), the rules in paragraph 12.4 apply in relation to the FCM.
12.4 For paragraph 12.3:
(a) if the private flight is conducted before any non-private flight is conducted — the private flight time must be taken to be part of the FCM’s FDP and must not be taken to be part of the FCM’s off-duty period; and
(b) if the private flight is conducted between non-private flights — the private flight time must be taken to be part of the FCM’s FDP and must not be taken to be part of the FCM’s off-duty period; and
(c) if:
(i) only 1 non-private flight is conducted during the FDP; and
(ii) the private flight is conducted after the non-private flight;
the private flight time must be taken to be part of the FCM’s duty period and must not be taken to be part of the FCM’s off-duty period; and
(d) if:
(i) more than 1 non-private flight is conducted during the FDP; and
(ii) the private flight is conducted after the last non-private flight;
the private flight time must be taken to be part of the FCM’s duty period and must not be taken to be part of the FCM’s off-duty period.
Note CAAP 48-01 provides examples of how to consider private flights within an FDP.
13 Operations under multiple Appendices
13.1 If, under paragraph 10.1, 2 or more Appendices apply to a single FDP of an FCM, the following rules apply for an operation undertaken at any particular time in the FDP:
(a) the maximum FDP that an AOC holder and an FCM must comply with is the FDP limit contained in the Appendix under which the operation is being conducted at that particular time;
(b) the maximum flight time that an AOC holder and an FCM must comply with is the flight time limit contained in the Appendix under which the operation is being conducted at that particular time.
13.2 In determining the maximum FDP and flight time under paragraph 13.1, the limit determined from each Appendix must be based on the time of commencement of the FDP, and not on the time of commencement of operations under each Appendix.
13.3 At any particular time in an FDP, the AOC holder and FCM must each ensure that the FCM remains within the cumulative duty and cumulative flight time limits for the Appendix under which the operation is being conducted at that particular time.
13.4 Where operations under 2 or more Appendices are undertaken in a single FDP, the minimum off-duty period that the AOC holder and FCM must comply with following the FDP is that contained in the Appendix with the highest off-duty period as if the entire FDP was performed under that Appendix.
13.5 Subject to paragraph 13A.2, an AOC holder and an FCM must comply with the off‑duty period requirements of the Appendix determined under paragraph 13.4 before the FCM commences another FDP.
13A Transitioning from Appendix 4B, 5 or 5A, or Subpart 137.Q of CASR
13A.1 Subject to paragraph 13A.2, an FCM, transitioning from the application of Appendix 4B, 5 or 5A, or Subpart 137.Q of CASR to his or her last FDP or standby, to the application of another Appendix of this CAO (other than Appendix 4B, 5 or 5A) (the other Appendix) to his or her next FDP or standby, must before commencing the next FDP or standby under the other Appendix, have had at least 6 days off-duty in the previous 28 consecutive days.
13A.2 Subject to paragraph 13A.3, if, despite paragraph 13A.1, an FCM has not had the minimum number of days off-duty that are specified under the subsection for the transition to the other Appendix, the FCM may commence a first FDP or standby under the other Appendix provided that:
(a) the off-duty period immediately before the first FDP or standby under the other Appendix is at least 12 hours; and
(b) the report time for the FCM for the first FDP is not earlier than 0700 hours local time; and
(c) the FCM’s previous FDP was less than 8 hours; and
(d) the first FDP is less than 8 hours in duration; and
(e) after the first FDP, there is only 1 subsequent FDP, also of less than 8 hours, before the requirements of paragraph 13A.1 must be complied with.
13A.3 Paragraph 13A.2 does not apply to a transition to Appendix 1.
14 AOC holder obligations
Fitness for duty
14.1 An AOC holder must not assign a duty on a flight to an FCM if the AOC holder reasonably believes that the FCM is unfit to perform the duty because of fatigue.
Limits
14.2 The limits and requirements that are to apply to an FCM must be determined in accordance with the Appendix chosen under this CAO to apply to the FCM.
Note The word “limit” in a provision refers expressly or impliedly to a quantity of time and, depending on the context and other language of the provision, is used to denote a maximum quantity of time that is not to be exceeded except in accordance with this CAO, or a minimum quantity of time that is not to be reduced except in accordance with this CAO.
Operations manual
14.3 The AOC holder must include in the operations manual:
(a) the limits arising from compliance with each applicable Appendix of this CAO that the holder has chosen to apply to an FCM, showing:
(i) each maximum limit under the Appendix which must not be exceeded; and
(ii) each minimum limit under the Appendix which must not be reduced; and
Note 1 For example, taking into account the provisions of an applicable Appendix, an FDP limit must not be exceeded, and an off-duty period must not be reduced.
Note 2 An AOC holder with an FRMS implementation approval must include relevant limits in the operations manual (see subclauses 2.5 and 3.2 in Appendix 7).
(b) for FCMs conducting a particular operation — each limit mentioned in subparagraph (a) as modified by the AOC holder for the FCMs and the operation, but not so as to exceed a maximum limit, or reduce a minimum limit, set out in the applicable Appendix; and
(c) where the need to take account of possible hazards arises under subsection 15 — for FCMs conducting a particular operation, each limit mentioned in subparagraph (b) as modified by taking the possible hazard into account.
Employee responsibilities
14.4 An AOC holder must set out in the operations manual its employees’ responsibilities for operational fatigue management, and fatigue risk management.
Meals
14.5 Except for operations under Appendix 7 — Fatigue Risk Management System (FRMS), where an FCM’s FDP is to exceed 5 hours, the AOC holder must provide the opportunity for the FCM to have access to adequate sustenance (a meal) during the first 5 hours and periodically after that meal, so that not more than 5 hours elapse between each meal.
Note For operations under Appendix 7, it is expected that the FRMS would provide the opportunity for FCMs to have access to adequate sustenance at appropriate intervals.
Records and reports
14.6 An AOC holder must maintain records (including relevant reports and documents) of the following:
(a) FCM rosters;
(b) actual duty periods;
(c) actual flight times of each FCM when acting in the capacity of a crew member;
Note Thus, the flight time record does not include time spent positioning.
(d) actual split-duty rest periods, standby periods and off-duty periods;
(e) any FDP that was extended under the relevant provision (if any) of the Appendix or FRMS which the AOC holder has chosen to comply with, including information about the extensions in such detail as enables the holder to comply with subparagraph 14.8 (a).
Note A record under subparagraph 14.6 (e) is not required where an FDP is reassigned under the relevant provision of the Appendix, unless the reassignment results in an FDP that exceeds the relevant limit set out in the AOC holder’s operations manual.
14.7 Each record mentioned in paragraph 14.6, including copies of reports and documents, must be securely retained for at least 5 years from the date the record and copy were made.
14.8 Each record concerning an extension of an FDP or a flight time limit mentioned in subparagraph 14.6 (e) must be:
(a) studied and used by the AOC holder to provide for continuous improvement of the holder’s fatigue management, and fatigue risk management policies; and
(b) promptly given to CASA, if so requested in writing.
Home base
14.9 Subject to paragraph 14.10, an AOC holder must:
(a) determine the home base for each FCM (a home base determination); and
(b) inform each FCM of his or her home base determination; and
(c) set out in its operations manual procedures for making a home base determination which ensure that each determination, and any changes to it, do not adversely affect aviation safety.
Note A determination of home base should be assigned with a degree of permanence.
14.10 Paragraph 14.9 does not apply for an AOC holder in relation to an FCM who only conducts operations for which the limitations and requirements are those set out in Appendix 5 or Appendix 5A.
Rosters
14.11 An AOC holder must publish each roster so far in advance of the FDPs and standby periods listed in it as to provide the FCM to whom it applies with a reasonable opportunity to plan adequate rest before his or her duty.
Note Guidance for AOC holders with regards to their obligations is contained in CAAP 48‑01.
15 Enhanced fatigue management obligations

16 Flight crew member obligations
16.1 For subregulation 11.068 (1) of CASR, it is a condition on each flight crew licence that the licence holder must not begin to carry out any task for a flight if, due to fatigue, the FCM is, or is likely to be, unfit to perform a task that the FCM must perform during the flight.
Note Guidance for FCMs on this obligation is contained in CAAP 48‑01.
16.2 The condition in paragraph 16.1 applies to an FCM regardless of whether the flight is conducted on behalf of an AOC holder, or a Part 138 operator, or a Part 141 operator, or as a private operation.
Note An FCM employed by an AOC holder must not exceed any limit specified for the FCM in the AOC holder’s operations manual, except where an extension is permitted.
APPENDIX 1 BASIC LIMITS
1.1 An FCM must not be assigned or commence an FDP commencing away from home base unless, within the 10 hours immediately before commencing the FDP, he or she has at least 8 consecutive hours’ sleep opportunity.
1.2 An FCM must not be assigned or commence an FDP commencing at home base unless, within the 12 hours immediately before commencing the FDP, he or she has at least 8 consecutive hours’ sleep opportunity.
Note See subsection 6 of this CAO for the definition of sleep opportunity where it is defined as occurring during an off-duty period.
2.1 An FCM may only be assigned an FDP that is between the following times:
(a) the earlier of the following:
(i) the beginning of morning civil twilight on a day;
(ii) 0700 hours local time on the day;

2.2 Subject to subclauses 2.1, 2.3 and 2.4, an FCM may be assigned an FDP that is not longer than 9 hours.
2.3 If an FCM is assigned an FDP that is to commence before 0600 hours local time, being after the beginning of morning civil twilight — the assigned FDP must not be longer than 8 hours.
2.4 If an FCM is assigned an FDP that is to commence at or after 1400 hours local time — the assigned FDP must not be longer than 8 hours.
Note If an FDP commences after 1700 hours on a day, the FDP must be less than 8 hours because, under paragraph 2.1 (b), an FDP must not end later than 0100 hours on the following day (all times being local time at the commencing location).
2.5 An FCM may be assigned an FDP that finishes after 2200 hours local time (a late FDP) only if not more than 3 late FDPs are assigned to the FCM in any 168 consecutive hours.
2.6 An FCM must not be assigned or commence flight time for flight training during an FDP unless the flight training is conducted during the first 7 hours of the FDP’s flight time.
2.7 An FCM must not exceed the flight time limit, or an FDP limit mentioned in subclause 2.2, 2.3 or 2.4, except in accordance with clause 3.
3.1 An FDP limit mentioned in clause 2 may be extended by up to 1 hour if:
(a) the FDP has commenced; and
(b) unforeseen operational circumstances arise; and
(c) an extension of the FDP is operationally necessary to complete the duty; and
(d) the FCM considers himself or herself fit for the extension.
Note 1 Under regulation 91.215 of CASR, the pilot in command of an aircraft is responsible for the conduct and safety of members of the crew on the aircraft and, therefore, has discretion not to permit an extension.
3.2 Flight training for up to 30 minutes may be conducted after the first 7 hours of the FDP’s flight time if:
3.3 An FDP limit must not be extended under this clause if it would cause an FCM to exceed the cumulative flight time limits in clause 5.
3.4 Despite any limit or number under this Appendix, if:
(b) the unforeseen operational circumstances would cause an FCM to exceed any limit or number permitted under this Appendix;
then, the flight may continue to the planned destination at the discretion of the pilot in command.
4 Off-duty period limits
4.1 An FCM must have a minimum off-duty period of at least 12 consecutive hours during any consecutive 24-hour period.
4.2 Before beginning an FDP, an FCM must have had:
(a) at least 36 consecutive hours off-duty, including 2 local nights, in the 168 hours before the projected end time of the assigned FDP; and
(b) at least 6 days off-duty in the 28 consecutive days before the FDP commences.
4.3 If an FDP under this Appendix is followed by an FDP under another Appendix, then, despite anything in the other Appendix, the FCM must have a minimum off‑duty period of at least 12 consecutive hours before commencing the FDP under the other Appendix.
5 Limit on cumulative flight time
5.1 The cumulative flight time accrued by an FCM during any consecutive 28-day period must not exceed 100 hours.
5.2 The cumulative flight time accrued by an FCM during any consecutive 365-day period must not exceed 1 000 hours.
APPENDIX 2 MULTI-PILOT OPERATIONS EXCEPT FLIGHT TRAINING

(b) subject to paragraph (c), if the commencement of the FDP has been delayed — the original reporting time for the FDP; or
(c) if the commencement of the FDP has been delayed by a single delay of 10 hours or more — commencing the FDP following the delay; or
1.2 An FCM must not be assigned or commence an FDP or standby commencing at home base unless he or she has at least 8 consecutive hours’ sleep opportunity within the 12 hours immediately before:
(b) subject to paragraph (c), if the commencement of the FDP has been delayed — the original reporting time for the FDP; or
(c) if the commencement of the FDP has been delayed by a single delay of 10 hours or more — commencing the FDP following the delay; or
Note See subsection 6 of this CAO for the definition of sleep opportunity, where it is defined as occurring during an off-duty period.
2 Limits for an acclimatised FCM
2.1 Subject to clause 5, an acclimatised FCM must not be assigned an FDP longer than the number of hours specified in Table 2.1 in this clause (the FDP limit), as determined by the acclimatised time at the start of the FDP and the number of sectors to be flown.
2.2 An acclimatised FCM must not be assigned flight time longer than 10.5 hours except in an augmented crew operation.
Note There is no flight time limit for an augmented crew operation.
2.3 In applying Table 2.1, first, choose the appropriate acclimatised time at which the FDP for the FCM is to start, then choose the number of sectors which are to be flown. The maximum FDP for the acclimatised FCM is the number under the chosen number of sectors that corresponds to the chosen acclimatised time at which the FDP for the FCM is to start.

APPENDIX 1 BASIC LIMITS
APPENDIX 2 MULTI-PILOT OPERATIONS EXCEPT FLIGHT TRAINING
Why it matters (official rationale and then what that implies economically and operationally)
Officially: the instrument is designed to manage fatigue‑related safety risk by setting time‑based limits and by requiring training, rostering, monitoring, record‑keeping and, where approved, data‑driven FRMS approaches (see Part 3, subsection 15 and Appendix 7).
What that implies in practical terms: operators must change rostering, staffing and training practices to fit the selected Appendix limits (clause 10.1, clause 14.3). That typically raises operating costs (more crew, altered schedules, back-up resources for delays) and creates a bookkeeping/administrative burden (detailed records retained for multi‑year periods — see clause 14.6–14.7). Operators who invest in an FRMS may gain scheduling flexibility but must invest in data systems, analytical capability and CASA approval processes (Appendix 7). CASA keeps discretionary control over approvals and may require amendments or revoke approvals if the FRMS doesn’t deliver acceptable safety outcomes (Appendix 7, clauses 7, 8–10).
Key mechanical features and rules to watch
Costs, incentives, trade‑offs and likely behaviour changes
Practical steps operators and crew must take
Bottom line (mechanical and economic)
The CAO converts fatigue‑risk management into a detailed set of time limits, processes and documentation obligations applicable to most commercial air operators and their flight crew (clauses 4, 10, 14, 16). It also builds a dual regulatory pathway: prescriptive limits (Appendices 1–6) or a CASA‑approved, data‑driven FRMS (Appendix 7). The instrument therefore increases operational and administrative costs for operators while offering a route to more flexible, scientifically justified rostering for those who can invest in FRMS and obtain CASA approval (Appendix 7). CASA retains substantial discretion to grant, condition or revoke approvals and to allow limited non‑compliance (subsection 5A, Appendix 7).
