only for clearing an aircraft for take-off.

12.3.3.5         The words "TAKE-OFF" must be used as the last words of a take-off clearance, except when the following information must be appended:

(a)         an instruction specifying a turn or circuit direction; or

(b)         at a military airfield the state of the arrestor system;

12.3.3.6         In all other cases, the words "TAKE-OFF" must be used as the last words of the take- off clearance.

12.3.3.7         Unless requested, a take-off clearance must not be issued to a helicopter when the tailwind component exceeds 5 KT.

12.3.3.8         Within controlled airspace and at a controlled aerodrome, helicopters may be granted an airways and/or take-off clearance from any area which is nominated by ATC or the pilot, and assessed by the pilot as being suitable as a HLS.

12.3.3.9         Within a Class D CTR, a clearance to take-off is a clearance to operate within the CTR.

12.3.4              Landing Clearances

12.3.4.1         Clearance to land must not be issued before:

(a)         the aircraft has commenced final approach of a PAR or straight in instrument approach; or

(b)         the aircraft has been sighted by the tower controller:

(i)            on the late downwind leg of the circuit pattern;

(ii)          on base leg; or

(iii)        on final in the case of a straight in visual approach.

12.3.4.2         Observation by radar satisfies the sighting requirement.

12.3.4.3         Unless requested by the pilot, a landing clearance must not be issued to a helicopter when the tailwind exceeds 5 KT.

12.3.4.4         When a tower controller has been advised that a general aviation aircraft with retractable undercarriage has experienced abnormal operations, a check gear down call must be made with the landing clearance.

12.3.4.5         A military aircraft must be instructed to check gear down when being cleared for an overshoot, cleared to land or cleared for a touch-and-go landing. Controllers must issue the instruction as soon as possible after a pilot indicates that his undercarriage is down and locked. Where a pilot neglects to declare his undercarriage status, the controller must instruct the pilot to check gear down.

12.3.4.6         If an arriving aircraft reports at a position where it should normally have been seen but has not been sighted, the aircraft must be advised of not being in sight by the controller when cleared to land.

12.3.4.7         Landing clearances must apply to aircraft which are restricted to the same or crossing landing paths. However, when such aircraft are permitted to land in parallel paths, clearances may be given for simultaneous landings. In these circumstances, notwithstanding that the pilot of each aircraft must be responsible for the maintenance of separation, the tower controller must issue alternative instructions should the possibility of a confliction arise.

12.3.4.8         The tower controller
