Order 7110.65P, Air Traffic Control, with changes

2/17/057110.65P CHG 2Section 9. Pacific ICAO Region8−9−1. APPLICATIONProvide air traffic control services in the PacificICAO Region with the procedures and minimacontained in this section except when notedotherwise.8−9−2. VERTICAL SEPARATIONProvide vertical separation in accordance withChapter 4, IFR, Section 5, Altitude Assignment andVerification, except when aircraft operate withinairspace where composite separation and proceduresare authorized, apply the minima specified inpara 8−9−5, Composite Separation Minima.8−9−3. LONGITUDINAL SEPARATIONIn accordance with Chapter 8, Offshore/OceanicProcedures, Section 3, Longitudinal Separation,apply the following:a. Minima based on time:1. 15 minutes between aircraft; or2. The prescribed minima in accordance withpara 8−3−3, Mach Number Technique.b. Minima based on distance using AutomaticDependent Surveillance − Contract (ADS−C):1. Apply the minima as specified in TBL 8−9−1,ADS−C Criteria, between aircraft on the same trackwithin airspace designated for Required NavigationPerformance (RNP), provided:(a) Direct controller/pilot communication viavoice or Controller Pilot Data Link Communications(CPDLC) is established, and(b) The required ADS−C periodic reports aremaintained and monitored by an automated flightdata processor (e.g., Ocean21);TBL 8−9−1ADS−C CriteriaMinima RNP Maximum ADS−CPeriodic ReportingInterval50 NM 10 27 minutes50 NM 4 32 minutes30 NM 4 14 minutes2. Aircraft on reciprocal tracks may be clearedto climb or descend to or through the altitude(s)occupied by another aircraft provided that:(a) An ADS−C position report on at least oneof the aircraft has been received beyond the passingpoint, and(b) The aircraft have passed each other by theapplicable separation minimum.NOTE−Ocean21 has been designed to check for the above criteriaprior to allowing the minima to be provided.3. When an ADS−C periodic or waypointchange event report is overdue by 3 minutes, thecontroller shall take action to obtain an ADS−Creport.4. If no report is received within 6 minutes of thetime the original report was due, the controller shalltake action to apply another form of separation.c. Minima based on distance without ADS−C:1. Apply 50 NM between aircraft cruising,climbing or descending on the same track orreciprocal track that meet the requirements for andare operating within airspace designated for RNP−10operations provided:(a) Direct controller/pilot communication viavoice or CPDLC is maintained; and(b) Separation is established by ensuring thatat least 50 NM longitudinal separation minima existsbetween aircraft positions as reported by reference tothe same waypoint.(1) Same track aircraft − whenever possibleahead of both; or(2) Reciprocal track aircraft − providedthat it has been positively established that the aircrafthave passed each other.Pacific ICAO Region8−9−1
