Oceanic and International Operations Special Areas of Operation (SAO)

Objectives At the end of this lesson, you will be able to: Identify the SAOs Identify the communication, navigation, and surveillance requirements for each SAO Identify the means for communicating clearances

Overview In this lesson we will discuss the following topics: Special Areas of Operation (SAO) Unrestricted operations Communication, navigation, and surveillance (CNS) requirements for each SAO Accessing the Virtual Oceanic Resource Guide (VORG)

Special Areas of Operation (SAO) C-Communication N-Navigation S-Surveillance

Unrestricted Operations NAT Organized Track System (OTS) NAT Track Message

Unrestricted Operations NAT Organized Track System (OTS)

Unrestricted Operations Unrestricted operations in the following geographic areas require two LRCS and two LRNS: NAT MNPS AMU

Unrestricted Operations Unrestricted operations in the following geographic areas require two LRCS and two LRNS: North Polar C-MNPS

Unrestricted Operations Unrestricted operations in the following geographic areas require two LRCS and two LRNS: North Pacific (NOPAC) Central East Pacific (CEP)

Unrestricted Operations Unrestricted operations in the following geographic areas require two LRCS and two LRNS: Oceanic Required Navigation Performance (RNP) (4/10)

Practice Exercise 1 PE-01-SAO-Key

North Atlantic Minimum Navigation Performance Specifications (NAT-MNPS) C-Communication For unrestricted operations, parts 91, 91 K, 121, 125, and 135 operations require two LRCS (Note: LRCS requirements are evolving) N-Navigation For unrestricted operations, two LRNS are required Northern contingency routes (Blue Spruce) require one LRNS S-Surveillance Procedural surveillance that requires giving voice or Data Link position reports

Initial Class II C-Communication N-Navigation S-Surveillance Requirements are dependent on area Gulf of Mexico normally requires no LRCS Pacific Ocean requires two LRCS (Note: LRCS requirements are evolving) N-Navigation Initial Class II operations normally require two LRNS Exception: WATRS and Gulf of Mexico operations require one LRNS (if authorized by OpsSpec) S-Surveillance Procedural surveillance that requires giving voice or Data Link position reports

Canadian-MNPS (C-MNPS) C-Communication Operations conducted in the C-MNPS require two LRCS (Note: LRCS requirements are evolving) N-Navigation C-MNPS operations require two LRNS S-Surveillance Procedural surveillance that requires giving voice or Data Link position reports

North Polar C-Communication N-Navigation S-Surveillance Operations conducted in the North Polar region require two LRCS (Note: LRCS requirements are evolving) N-Navigation North Polar region operations, outside AMU, require two LRNS Operations within AMU require two LRNS, each with inertial navigation platform capability S-Surveillance Procedural surveillance that requires giving voice or Data Link position reports

Areas of Magnetic Unreliability (AMU) C-Communication Operations conducted in the AMU require two High Frequency (HF) radios (Note: LRCS requirements are evolving) N-Navigation AMU operations require two LRNS, each with an inertial navigation platform S-Surveillance Procedural surveillance that requires giving voice or Data Link position reports

North Pacific (NOPAC) C-Communication Unrestricted operations conducted in the NOPAC require two LRCS (Note: LRCS requirements are evolving) N-Navigation NOPAC operations require two LRNS S-Surveillance Procedural surveillance that requires giving voice or Data Link position reports

Central East Pacific (CEP) C-Communication Unrestricted operations conducted in the CEP require two High Frequency (HF) Radios (Note: LRCS requirements are evolving) N-Navigation CEP operations require two LRNS S-Surveillance Procedural surveillance that requires giving voice or Data Link position reports

Basic Area Navigation/Precision Area Navigation BRNAV/PRNAV (RNAV5/RNAV1) C-Communication BRNAV/PRNAV (RNAV5/RNAV1) operations require Very High Frequency (VHF) Radios (8.33 kHz and FM Immunity) (Note: LRCS requirements are evolving) N-Navigation Single Area Navigation System (RNAV) system required S-Surveillance ATC Radar

Russia and China C-Communication Two Very High Frequency (VHF) Radios Consult Aeronautical Information Publication (AIP) for LRCS requirements (Note: LRCS requirements are evolving) N-Navigation Consult AIP for LRNS requirements S-Surveillance ATC Radar

Gulf of Mexico/Caribbean/WATRS C-Communication Two Very High Frequency (VHF) Radios Some areas may require a single LRCS (if below Flight Level (FL) 180) (Note: LRCS requirements are evolving) N-Navigation One LRNS may be authorized (OpSpec B054) S-Surveillance Procedural surveillance that requires giving voice and/or Data Link position reports

WATRS Plus 5 June 2008 40% more routes and flight levels Increased fuel efficiency AR Routes Yankee Routes Ops Specs reviews noted numerous Class II approvals issued with little or no validation (WATRS/GOMEX)

Q&A How are AR and Yankee routes authorized for operators?

Oceanic Required Navigation Performance (RNP) (4/10) C-Communication Two LRCS required (Note: LRCS requirements are evolving) N-Navigation Two LRNS required RNP-4 must be GNSS based S-Surveillance Procedural surveillance that requires giving voice or Data Link position reports

Other Class II Areas C-Communication N-Navigation S-Surveillance Operations normally require two LRCS (Note: LRCS requirements are evolving) N-Navigation Operations normally require two LRNS S-Surveillance Procedural surveillance that requires giving voice or Data Link position reports
