SECTION 1
General Operational Policy/Procedures and Information Applicable To Pacific Operations

CNS Equipage Requirements and Options:
Oakland and Anchorage Oceanic Airspace (14 Mar 07)
FAA Notice: Operational Policy/Procedures For Pacific Oceanic & Offshore Airspace (16 Feb 06):
- Summary of Pacific RVSM Policies
- In-flight Contingency Procedures For Rapid Descent, Turn-back or Diversion
- Weather Deviation Procedures
- Strategic Lateral Offset Procedures (to mitigate wake turbulence and collision risk)

SECTION 2
CNS Requirements and Operational Policy/Procedures For 50nm Lateral and 50nm Longitudinal Separation

Overview: Minimum CNS Requirements For 50/50
- 50nm Lateral Separation
- Comm - HF Voice
- Nav - Required Navigation Performance 10 (RNP-10) or better (e.g., RNP-4)
- Surveillance - HF Voice position reports
- 50nm Longitudinal Separation
- Comm - Direct Controller-Pilot Communications (DCPC) via VHF voice or Satellite Controller-Pilot Datalink Communication (CPDLC) and, for oceanic operations, HF voice communications capability.
- Nav - RNP-10 or better (e.g., RNP-4) is required. (Aircraft equipped with enhanced CNS capabilities will generally meet RNP-4 or better).
- Surveillance - normal practice in the Anchorage and Oakland FIRs will be to apply 50nm longitudinal separation between aircraft pairs only when ADS-C surveillance is available.
Policy and Procedures: Satellite CPDLC (Controller-Pilot Datalink Communication) and Satellite ADS-C (Automatic Dependant Surveillance-Contract). See the following documents on the Data Link section of this web site:
- AC 120-70A (Operational Authorization Process For Use of Data Link Communication System)
- Data Link Approval Checklist
- Operator Guide to Datalink Approval
- FANS-1/A Operations Manual (FOM). The FOM is posted in Section 3, item 3C. The FOM contains policy and procedures for using CPDLC and ADS-C in the FIRs listed in FOM paragraph 1 (Introduction).
RNP-10 Navigation Requirements -
FAA Order 8400.12A (Required Navigation Performance 10 (RNP-10) Operational Approval (2/9/98))
General Operational Policy/Procedures -
The FAA Notice, “Operational Policy/Procedures For Pacific Oceanic Airspace”, posted in Section 1 applies.

SECTION 3
CNS Requirements and Operational Policy/Procedures For 30nm lateral and 30nm Longitudinal Separation (30/30)

Overview: Minimum CNS Requirements for 30/30
- 30nm Lateral and Longitudinal Separation
- Comm - Satellite CPDLC or VHF voice and, for oceanic operations, HF voice communications capability
- Nav - RNP-4 or better
- Surveillance - Satellite ADS-C
30/30 Operational Policy & Procedures and Program Information -
- New! FAA Notice: Limited Trial for 30 NM Separation and Limited Use of 50 NM Longitudinal Separation (06 June 07)
- General Operational Policy/Procedures. The FAA Notice, “Operational Policy/Procedures For Pacific Oceanic Airspace” posted in Section 1 applies.
Policy and Procedures: Satellite CPDLC (Controller-Pilot Datalink Communication) and Satellite ADS-C (Automatic Dependant Surveillance-Contract). See the following documents on the Data Link section of this web site:
- AC 120-70A (Operational Authorization Process For Use of Data Link Communication System)
- Data Link Approval Checklist
- Operator Guide to Datalink Approval
- FANS-1/A Operations Manual (FOM). The FOM is posted in Section 3, item 3C. The FOM contains policy and procedures for using CPDLC and ADS-C in the FIRs listed in FOM paragraph 1 (Introduction).
RNP-4 Navigation Requirements
Operator note: U.S. operators will use FAA Order 8400.33. Non-U.S. operators should use one of the documents listed below to obtain RNP-4 or better authorization:
- FAA Order 8400.33 (Procedures For Obtaining Authorization For Required Navigation Performance 4 (RNP-4) Oceanic and Remote Area Operations)
- Australian Civil Aviation Safety Authority (CASA) Advisory Circular 91U-3(0). To be posted when available.
- ICAO State Letter and attached Performance Based Navigation Manual (New Doc 9613), Vol. II (Implementation of PBN Operations). See RNP 4 guidance in pdf pages 97-109 (C-1-1 to C-1-12) in PBN Manual, Vol. II
- Part C, Chapter 1 (Implementing RNP 4): Table of Contents

SECTION 4
RVSM (Reduced Vertical Separation Minimum)

RVSM Documentation Webpage The RVSM Documentation Webpage provides policy documents and references for operators that are seeking RVSM approval.
Policies and Procedures for Asia/Pacific Ocean Area of Operations The Asia/Pacific section of the RVSM Documentation Webpage contains operational policy and information for that area. The FAA Notice “Operational Policy/Procedures For Pacific Oceanic & Offshore Airspace” posted in Section 1 is also posted on the RVSM Documentation Webpage.
