Question 1

What restrictions, if any, are placed on traffic during the limited ATS phase?

Answer 1

• the Auckland OCA remains Class A airspace and an air traffic control service shall be provided
• traffic flow management procedures will be implemented
• all ATS fixed routes remain available, no flex tracks or user preferred routes

Question 2

Who is responsible for issuing the OCS flow NOTAM?

Answer 2

Oceanic Team Leader

Question 3

Who shall decide when ATS delivery shall be resumed from either the OCS main or reserve platforms?

Answer 3

Oceanic Team Leader

Question 4

What systems is the CNS/ATM system based on?

Answer 4

Global navigation systems, global communication systems and automatic dependent surveillance.

Question 5

Are VFR flights permitted in Oceanic Class G airspace?

Answer 5

Yes.

Question 6

Why is end to end monitoring of the FANS 1/A CNS/ATM system required?

Answer 6

Because of the integrated nature of the system and the degree of interaction between it’s components.

Question 7

How will an aircraft operator indicate that the appropriate state authority has approved the aircraft for RVSM operation?

Answer 7

The letter W inserted in Field 10a of the ICAO flight plan.

Question 8

When are aircraft entering airspace within which a larger lateral separation minimum applies than that which applies to the airspace being exited considered separated, and what is the minimum navigation requirement?

Answer 8

Aircraft are flying on tracks that:

• are separated by appropriate (lateral or radar) separation for the airspace are being exited, and
• diverge by 15 degrees or more until the larger separation minima has been established, and
• aircraft have the navigation capability to ensure correct track guidance
• RNP 10 or better
• INS/IRS + FMS
• GNSS

Question 9

When may an aircraft which is not RVSM approved, flight plan to operate within RVSM airspace?

Answer 9

When a non-RVSM civil aircraft is:

• being initially delivered to the state of registry or operator, or
• was formerly RVSM approved but has experienced an equipment failure and is being flown to a maintenance facility for repair in order to meet RVSM requirements and/or obtain approval, or
• is transporting a spare engine or strut assembly externally, or
• is being utilised for mercy or humanitarian purposes

Question 10

Do RVSM aircraft have level priority over non-RVSM aircraft?

Answer 10

Yes. A non-RVSM state aircraft shall be afforded the same priority as a RVSM approved aircraft.

Question 11

When can RVSM levels be used outside of RVSM airspace?

Answer 11

Only as part of a block clearance.

Question 12

When shall Oceanic controllers suspend RVSM operations for an individual aircraft

Answer 12

When the pilot reports:

• the aircraft is no longer RVSM compliant, or
• the aircraft has encountered severe turbulence

Question 13

When aircraft are unable to meet their filed RNP value, when are the pilots required to advise ATC?

Answer 13

• 30 minutes prior to entry to RNP airspace, or

- immediately, when within 30 minutes of, or in RNP airspace

Question 14

May aircraft which are non-compliant with RNP 10 be permitted to operate in the RNP area?

Answer 14

Yes.

Question 15

Detail the requirements of applying D50RNP longitudinal separation in RNP10 airspace.

Answer 15

• same/reciprocal/parallel reciprocal tracks
• CPDLC and ADS-C connection
• when at or near minimum distance, speed control shall be applied
• if able, prior to applying separation, controller should determine adequacy of datalink communications
• not less than 50NM between aircraft by means of ADS position reports
• ADS-C reports at least every 27 minutes
• if report not received within 3 mins, OCS automatically initiates on-demand and posts message to sector queue
• if report not received within 6 mins, OCS automatically:
  
  • sends on-demand
  • deselects D flag
  • posts message to sector queue
  • initiates conflict probe
