the lifting.
Note   An example of an operation involving a Class C external load is powerline stringing.
Class D external load means a load that is a person, carried external to the rotorcraft, by a rotorcraft in an external load operation (which under this MOS is called a Class D external load operation).
Note   Examples of operations involving a Class D external load are the following: winching a person on board from land or water; winching a person already aboard onto land or into the water; positioning a person on or at a transmission wire using a fixed line attached to the rotorcraft's belly hook; carrying a person on a platform; conducting a person's hover exit from, or entry to, the rotorcraft. The belly hook, winch, hard point, or platform must be approved for the purpose of the lifting, placement or carrying of the person (see for example, subsection 15.06 (4)). Only an aerial work certificate holder may carry out a Class D external load operation — see generally subregulations 138.005 (3) and 138.030 (1).
Class E external load means a load, carried by an aeroplane in an external load operation (which under this MOS is called a Class E external load operation) that is:
(a) external to the aeroplane; and
(b) jettisonable; and
(c) either:
           (i) attached to the exterior of the aeroplane; or
           (ii) picked up, towed, and released by, the aeroplane.
Note 1   An example of an operation involving a Class E external load is a banner towing operation by an aeroplane.
Note 2   Glider towing is excluded from the definition of aerial work operation by paragraph 138.010 (5) (c). Therefore, a glider that is towed by an aeroplane is not a Class E load.
cloud seeding, for a dispensing operation, means the dropping of approved substances from an aeroplane flying though, or above, cloud formations, for the purpose of causing precipitation from the clouds.
emergency service operation has the meaning given by Part 1 of the CASR Dictionary.
ESO means an aerial work operation that is part of an emergency service operation.
Note   Emergency service operation is defined in the CASR Dictionary.
ESO operating site means:
(a) a location on ground or water, on a vessel, or on an offshore facility, at or from which an aircraft lands or takes off for the purposes of an ESO, or for training for an ESO; or
(b) a position in the air at which a rotorcraft hovers for carrying out an aerial work operation as part of an ESO or training for an ESO.
Note   ESO operating sites are places where an aerial work objective is actually carried out, for example, a clearing or reserve adjacent to a
