Class A external load means a load that is not a person, carried by a rotorcraft in an external load operation (which under this MOS is called a Class A external load operation) that:
(a) is external to the rotorcraft; and
(b) is not carried in an approved cargo rack, or in a sealed receptacle; and
(c) is not jettisonable; and
(d) cannot move freely; and
(e) does not extend below the rotorcraft's landing gear.
Note   An example of an operation involving a Class A external load is when a load is carried on a platform from which the load has the potential to fall off if it is not properly secured. See the definition of sealed receptacle which means a belly tank for firefighting, or a cargo pod, basket, bin, or similar thing in which a load can be fully enclosed and sealed.
Class B external load means a load that is not a person, carried by a rotorcraft in an external load operation (which under this MOS is called a Class B external load operation) that is:
(a) external to the rotorcraft; and
(b) jettisonable; and
(c) carried above or below the rotorcraft's landing gear; and
(d) by using the rotorcraft's belly hook or winch:
           (i) lifted off land or water, or off a structure that is on land or water; and
           (ii) carried in flight; and
           (iii) set down on land or water, or on a structure that is on land or water.
Note   An example of an operation involving a Class B external load is the picking up and carriage, using a sling attached to the belly hook of a rotorcraft, of an air-conditioning unit that is then set down on the roof of a tall building.
Class C external load means a load that is not a person, carried by a rotorcraft in an external load operation (which under this MOS is called a Class C external load operation):
(a) that is external to the rotorcraft; and
(b) that is jettisonable; and
(c) part of which remains in contact with land or water during 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
