‘Rotorcraft’ means a heavier-than-air aircraft that depends principally for its support in flight on the
lift generated by one or more rotors.

'Rotorcraft-load combination’ means the combination of a rotorcraft and an external-load,
including the external load attaching means. Rotorcraft-load combinations are designated as Class A,
Class B, Class C and Class D as follows:
a. Class A rotorcraft-load combination means one in which the external load cannot move
freely, cannot be jettisoned, and does not extend below the landing gear.
b. Class B rotorcraft-load combination means one in which the external load is jettisonable and
is lifted free of land or water during the rotorcraft operation.
c. Class C rotorcraft-load combination means one in which the external load is jettisonable and
remains in contact with land or water during the rotorcraft operation.
d. Class D rotorcraft-load combination means one in which the external load is other than a
Class A, B or C and has been specifically approved by the Authority for that operation.

Radar position indication (RPI). The visual indication, in
non-symbolic and/or symbolic form, on a radar display of
the position of an aircraft obtained by primary and/or
secondary surveillance radar.

'rpm’ means revolutions per minute.

Radar position symbol (RPS). The visual indication, in
symbolic form, on a radar display, of the position of an
aircraft obtained after automatic processing of positional
data derived from primary and/or secondary surveillance
radar.

Runway guard lights. A light system intended to caution pilots or vehicle drivers that they are about to enter an active runway.

Runway strip. A defined area including the runway and stopway, if provided, intended:
a) to reduce the risk of damage to aircraft running off a runway; and
b) to protect aircraft flying over it during take-off or landing operations.

Runway turn pad. A defined area on a land aerodrome adjacent to a runway for the purpose of completing a 180-degree turn on
a runway.

“runway visual range” (RVR) means the range over which the pilot of an aircraft on
the centre line of a runway can see the runway surface markings or the lights
delineating the runway or identifying its centre line

“runway-holding position” means a designated position intended to protect a runway, an
obstacle limitation surface, or an ILS/MLS critical or sensitive area at which taxiing
aircraft or vehicles shall stop and hold, unless otherwise authorised by the aerodrome
control tower to proceed
