General Operational Policy/Procedures and Information Applicable To Pacific Operations

• CNS Equipage Requirements and Options (MS Word): Oakland and Anchorage Oceanic Airspace (14 Mar 07)
• FAA Notice: Operational Policy/Procedures For Pacific Oceanic & Offshore Airspace (16 Feb 06) (MS Word):
  • Summary of Pacific RVSM Policies

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
  • ICAO Global Operational Data Link Document (GOLD).The GOLD contains policy and procedures for using CPDLC and ADS-C.
• RNP-10 Navigation Requirements - FAA Order 8400.12C (PDF)(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 -
  • FAA Notice: Oaklnd Oceanic Control Area (CTA) 30 Nautical Mile (nm) Lateral/30 nm Longitudinal Separation (30/30) 50 nm Longitudinal Separation (D50) (MS Word)
  • 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
  • ICAO Global Operational Data Link Document(GOLD).The GOLD contains policy and procedures for using CPDLC and ADS-C.
• 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 (MS Word)(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) (PDF). 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 (MS Word)

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.
