  1. NOPAC OPERATIONS

  2. Pacific Ocean Operations • Regions: • Northern Pacific(NOPAC) • Southern Pacific(SOPAC) • Central Pacific(CENPAC) • Central East Pacific (CEP) • Source Material: • ICAO Regional Supplement Procedures Manual and AC 91-70 • NOPAC defined by US Government FLIP Regional Alaska and Chart Supplements

  3. NOPAC Organized Track System • Five ATS routes linking Anchorage and Tokyo • Tokyo FIR to Composite Routes (OTR) • Composite Routes to ANC FIR (ATR)

  4. R220(n), R580(o), A590(p), R591(a), G344(c) Two northern routes westbound. Peak times 1200 to 1900 UTC and 2200-0800 UTC Three southern routes eastbound. Peak times 0700-2100 UTC Exceptions: A591/G344 bidirectional PACOTS routes (see ball notes) This occurs when other routes are saturated

  5. General Information • ANC ARTCC NOTAMS specify preferential routes within ANC FIR. Denotes times and routes westbound/eastbound • Flight plan required for each Composite Route for direction of flight plus bi- • directional routes • If opposite to peak flow, expect possible reroutes and low altitude restriction

  6. General Information • Reroutes occur! Refer to Jepp P(H/L)1 chart panel. Expect partial clearance until in contact with next agency NOPAC is RNP-10 airspace, R on ICAO • flight plan block 10 confirms certification Oceanic Clearance is inherent in the clearance for the flight. A separate oceanic clearance as with NAT, is NOT required

  7. NOPAC Westbound • Preferred routes announced daily via NOTAM through ANC ARTCC • Entering Composite System westbound between 0400 -2000 UTC must file via • R220 • Entering between 2200-0300 UTC potential • 10 minutes restriction between departures

  8. NOPAC Eastbound • Oceanic Transition Routes (OTR): Connect Japanese Airspace to NOPAC • Normal VHF (119.1Mhz, backup 128.2Mhz) contact points with ANC: • A590 150nm west of PINSO • R591 150nm west of Shemya (SYA) • G344 150nm west of CHIPT

  9. NOPAC Specifics • Climbs Eastbound: Even though annotated on flight plan, request when climb is desired. Included in your first mandatory position report (when unable CPDLC) • Revise position estimates when in error by MORE than 3 minutes • Utilize 123.45Mhz for Class II air-to-air andmonitor 121.5Mhz • Comm failures in accordance with ICAO

  10. NOPAC Specifics • Communication: Standard Class II communications apply • HF must be checked before departure in case of CPDLC failure, additionally, an HF SELCAL check must be obtained. • Like NAT OPS, HF radio operators have no authority to issue ATC clearances and must relay to the appropriate traffic control center • Meteorology Reports: In accordance with ICAO Transponder Ops: Set 2000 west of 164E. As assigned east there of OR 2000 if not assigned

  11. NOPAC CPDLC One position report over FIR boundary Discontinue position reports until next FIR crossing assigned east there of OR 2000 if not assigned

  12. NOPAC Specifics Freqs • Tokyo or San Francisco HF station crossing

  13. NOPAC Special Reporting Procedure 10 minutes restriction between departures assigned east there of OR 2000 if not assigned

  14. NOPAC Position Reports CPDLC Inop • Crossing FIR s: The last position report prior to transition shall also be made to the ATS unit serving the airspace about to be entered. • Fukuoka copy Anchorage • Position reporting per ICAO, when on Random Route: East/West operations include latitude in degrees and minutes, with longitude in degrees only • When reporting ensuing position, the next • succeeding position must be reported whether • compulsory or not (an important difference from most international regions) most international regions)

  15. NOPAC Separation • RNP-10 applies; 25nm lateral either side of centerline (50nm total) and RVSM 300m (1000ft) vertical separation minimum (FL290-410) (100nm lateral below FL180) • Longitudinal Separation: 15 minutes in trail most international regions)

  16. NOPAC Separation • RNP-10 requires certification in Ops Specs • Mach Number Technique, same as for NAT operations except: ATC approved Mach number will be included in each clearance given by Anchorage and Oakland Oceanic when this technique is applied most international regions)

  17. NOPAC In-flight Contingencies In addition to ECAM / QRH and FCOM procedures the following applies: Assess and Continue so long as degradation does not require a diversion from track Advise ATC immediately so separation criteria can be adjusted accordingly Use Mayday only if necessary Report malfunctions including any navigation degradation per ICAO procedure Nav degradation: Begin special monitoring procedure according to ICAO MNPS Manual most international regions)

  18. NOPAC In-flight Contingencies Nav Degradation: Monitor all remaining Nav systems carefully Check main and standby compasses against all available info Search for other aircraft contrails as needed. Use TCAS for separation Communicate on 123.45 and search for other aircraft near you Same track, level and route aircraft may help with drift, correct heading and wind information. most international regions)

  19. NOPAC In-flight Contingencies Pilot should: Continuously assess Prepare proposals with ATC Advise and request most suitable action Obtain clearance prior to any diversion most international regions)

  20. NOPAC Unable to Maintain Clearance If unable to comply with ARTCC: Advise ARTCC Use VHF as practicable to inform other aircraft nearby Turn all exterior lights ON On R220 avoid northward diversion due to Russian Federation FIR Unable to contact ATC: Use VHF if in range with certain local comm areas such as Adak Approach on 134.1 (refer to freq slide) most international regions)

  21. NOPAC Unable to Maintain Clearance Offset at least 45 degrees right or left when possible to obtain a 15nm offset track from intended new track If ABLE to maintain assigned altitude: When BEYOND 10nm make FLCH to 150m (500ft) above/below assigned altitude If returning to coarse track BE AT track altitude prior to 10nm offset most international regions)

  22. NOPAC Unable to Maintain Clearance Unable to maintain level: Laterally offset left or right 15nm Descend 150m (500ft) Apply minimize vertical rate until beyond SLOP zone most international regions)

  23. NOPAC Unable to Maintain Clearance Course Reversal: Continuous turn to intercept new track course ASAP, preferably before 10nm of new track Overshoot possible, be vigilant for other aircraft nearby Be AT new altitude 10nm prior to new course centerline most international regions)

  24. NOPAC Weather Deviations Maintain ICAO procedure for Class II deviations except: Notify ATC Expedite using Pan,Pan,Pan if required Advise extent of deviation if able most international regions)

  25. NOPAC Weather Deviations With no horizontal conflict ATC may first issue a vertical separation clearance followed by clearance to deviate laterally If conflicting vertical traffic and ATC cannot establish separation ATC will so advise by identifying position of conflicting traffic Pilots should then suggest a course of action most international regions)

  26. NOPAC Weather Deviations Unable ATC contact or revised clearance unavailable: Deviate as needed, follow ATC advised altitude until 10nm off track If deviation is less than 10nm either side of coarse REMAIN AT ASSIGNED ALTITUDE If deviation is in excess of 10 nm either side of course, follow the following criteria: most international regions)

  27. NOPAC Weather Deviations “Remember: Descend toward the pole”

  28. NOPAC Weather Deviations • When returning back to track, BE AT assigned flight level crossing within 10nm • of track • If contact was not established prior to deviation, continue to attempt contact to obtain a clearance • Advise ATC of intentions and obtain essential traffic information while deviating
