CHAPTER 18 PERFORMANCE – TAKE-OFF AND LANDING – AIRCRAFT
Division 1 Take-off and landing performance – large aeroplanes – all aerial work operations
18.01 Application
(1) This Division applies to the following operators (relevant operators):
(2) This Division applies only in relation to the operation by a relevant operator of the following aeroplanes (large aeroplanes):
(a) a propeller-driven, multi-engine aeroplane with an MTOW of more than 5 700 kg;
(b) a jet-driven, multi-engine aeroplane with an MTOW of more than 2 722 kg.
18.02 Take-off and landing performance for large aeroplanes
For subregulations 138.435 (2) and 138.440 (2), the prescribed requirements relating to take-off performance and landing performance for a flight of an aeroplane to which this Division applies are the requirements specified in Chapter 9 of the Part 121 MOS.
Division 2 Take-off and landing performance – rotorcraft – aerial work certificate holders only
18.03 Application
(1) This Division applies only to an aerial work certificate holder (a relevant operator).
(2) This Division applies only in relation to the operation by a relevant operator of any of the following rotorcraft:
(a) a multi-engine rotorcraft required to be operated with OEI accountability in accordance with this MOS;
(b) a single-engine rotorcraft operated with OEI accountability as defined in subsection 1.04 (6).
18.04 Take-off and landing performance for rotorcraft operated with OEI accountability
For subregulations 138.435 (2) and 138.440 (2), the prescribed requirements relating to take-off performance and landing performance for a flight of a rotorcraft to which this Division applies are the following:
(a) for a relevant operator of a multi-engine rotorcraft who chooses to operate within the requirements of paragraph (a) of the definition of OEI accountability — the requirements for PC1, PC2 or PC2WE (as applicable) specified in Chapter 10 of the Part 133 MOS;
(b) for a relevant operator of a multi-engine rotorcraft who chooses to operate within the requirements of paragraph (b) or (c) of the definition of OEI accountability — the requirements specified in the rotorcraft flight manual, as applicable to the operation;
> Note For the definition of OEI accountability for the flight of a multi-engine rotorcraft, see subsection 1.04 (6).
(c) for an operator of a single-engine rotorcraft who chooses to operate within the requirements of paragraph (a) of the definition of OEI accountability — the requirements relating to PC3 specified in Chapter 10 of the Part 133 MOS;
(d) for an operator of a single-engine rotorcraft who chooses to operate within the requirements of paragraph (b) or (c) of the definition of OEI accountability — the requirements specified in the rotorcraft flight manual, as applicable to the operation.
> Note For the definition of OEI accountability for the flight of a single-engine rotorcraft, see subsection 1.04 (6).
Division 3 Take-off and landing performance – other aircraft – all aerial work operations
18.05 Application
(1) This Division applies to the following operators (a relevant operator):
(2) This Division applies only in relation to the operation by a relevant operator of an aircraft to which Division 1 or Division 2 does not apply.
18.06 Take-off and landing performance for other aircraft
For subregulations 138.435 (2) and 138.440 (2), the prescribed requirements relating to take-off performance and landing performance for a flight of a relevant operator’s aircraft to which this Division applies are the requirements specified in the following:
(a) Chapters 24 and 25 of the Part 91 MOS (the Chapters) as if:
(i) the contents of each of the Chapters were incorporated into this section; and
(ii) references in the contents of the Chapters to any provision of Part 91 or the Part 91 MOS were deleted; and
(iii) the contents of the definition of any expressions used in either of the Chapters, as set out in subsection 1.07 (6) of the Part 91 MOS, were incorporated into this section with any references to Part 91, or the Part 91 MOS, deleted;
(b) the AFM.
CHAPTER 19 RESERVED
CHAPTER 20 RESERVED
CHAPTER 21 WEIGHT AND BALANCE
21.01 Application
21.02 Procedures for loading aircraft — document carriage
For subregulation 138.460 (2), the operator must ensure that when the flight of an aircraft begins:
(a) the aircraft is carrying completed weight and balance documents; and
(b) copies of the documents are available to CASA on request.
> Note 1 The expression weight and balance documents is defined in the CASR Dictionary.
> Note 2 Weight and balance documents should be retained by the operator in safe custody for at least 3 months after the flight.
21.03 Weight and balance documents
(1) For subregulation 138.460 (1), this section prescribes:
(a) the weight and balance documents that are required for a relevant aircraft used in an aerial work operations; and
(b) requirements in relation to those documents.
(2) For paragraph (1) (a), a load sheet, or other weight and balance document is required.
(3) For paragraph (1) (b), the load sheet or other weight and balance document must be:
(a) as described in the operator’s operations manual; and
(b) suitable to perform the function of a load sheet for the operations.
(4) In this section:
> load sheet means a form for recording:
(a) the weight and disposition of the disposable load on the relevant aircraft; and
(b) other loading information relevant for the operation.
> relevant aircraft means an aircraft with a MTOW exceeding 5 700 kg, but not an aircraft which, for design reasons, is demonstrably impossible to load in a manner that ensures that its centre of gravity would fall outside the approved range during the aerial work operation.
