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 must allocate one landing sequence number to a landing formation, thus treating the formation as one aircraft.

12.3.4.9         When the landing area is occupied by another aircraft or is obstructed, arriving aircraft may be issued with a clearance to:

(a)         continue approach if there is no immediate assurance that the landing areas will become available. This must be followed by the appropriate clearance; or

(b)         go around, or orbit if in a position to do so, should the landing area not be available. When required, a clearance to commence a second approach or hold must follow these instructions. The nature of the obstruction must be advised if not apparent to the approaching aircraft.

Section 13.1:   Weather Deviation and RVSM Contingency Procedures

13.1.1              Weather Deviation in Oceanic Airspace

13.1.1.1         In order to indicate priority, the pilot may initiate communication by stating "WEATHER DEVIATION REQUIRED". The pilot retains the option of initiating the communications using the urgency call "PAN PAN" three times to alert all listening parties of a special handling condition which will receive ATC priority for issuance of a clearance or assistance.

13.1.1.2         When a pilot requests clearance to deviate from track, the controller must:

(a)         issue a clearance to deviate from track, if there is no conflicting traffic in the lateral dimension; or

(b)         establish vertical separation and issue a clearance to deviate from track, if there is conflicting traffic in the lateral dimension; or

(c)          if unable to establish vertical separation, and there is conflicting traffic in the lateral dimension;

(i)            advise the pilot that clearance for the requested deviation is not available;

(ii)          provide traffic about, and to, all affected aircraft; and

(iii)        request pilot intentions.

       Note Position may be expressed as direction and distance, or actual or estimated location or ATS route/ track code.

13.1.2              Aircraft Equipment Failures in RVSM Airspace

13.1.2.1         If a pilot of an RVSM approved aircraft operating in the RVSM flight level band advises "NEGATIVE RVSM", the controller must, as required:

(a)         pass traffic information;

(b)         obtain the pilot's intentions;

(c)          provide alternative separation;

(d)         update the FDR; and

(e)         advise adjacent ATC facilities/sectors of the situation.

13.1.2.2         If a pilot advises that redundancy in primary altimetry systems is lost, but the remaining altimetry system is functioning normally, the controller should acknowledge the situation and continue to monitor the flight's progress.
Note: RVSM separation may still be applied in this instance.
