8/5/047110.65P CHG 1Section 7. North Atlantic ICAO Region8−7−1. APPLICATIONProvide air traffic control services in the NorthAtlantic ICAO Region with the procedures andminima contained in this section except when notedotherwise.8−7−2. VERTICAL SEPARATIONProvide vertical separation in accordance withChapter 4, IFR, Section 5, Altitude Assignment andVerification.8−7−3. LONGITUDINAL SEPARATIONIn accordance with Chapter 8, Offshore/OceanicProcedures, Section 3, Longitudinal Separation,apply the following:a. Supersonic flight:1. 10 minutes provided that:(a) both aircraft are in level flight at the sameMach number or the aircraft are of the same type andare both operating in cruise climb, and one of thefollowing;(1) The aircraft concerned have reportedover a common point; or,(2) If the aircraft have not reported over acommon point, the appropriate time interval beingapplied between aircraft exists and will exist at thecommon point; or,(3) If a common point does not exist, theappropriate time interval being applied betweenaircraft exists and will exist at significant points alongeach track.2. 15 minutes between aircraft in supersonicflight not covered in subpara a1 above.b. Turbojet operations (subsonic flight):1. Apply the prescribed minima in accordancewith para 8−3−3, Mach Number Technique; or2. Where tracks diverge from the common pointand the following aircraft is maintaining a greaterMach Number than the preceding aircraft:(a) At least 10 minutes longitudinal separationexists at the point where the tracks diverge; and(b) At least 5 minutes longitudinal separationwill exist where minimum lateral separation isachieved (whichever is estimated to occur first);(1) At or before the next significant point(normally within ten degrees of longitude alongtrack(s)), or(2) Within 90 minutes of the time thefollowing aircraft passes the common point, or(3) Within 600 NM of the common point.3. Apply 15 minutes between all other turbojetaircraft.c. Nonturbojet operations:1. Apply 20 minutes between aircraft operatingin the West Atlantic Route System (WATRS), or2. Apply 30 minutes between aircraft operatingoutside of the WATRS.NOTE−The WATRS area is defined as beginning at a point2700’N/7700’W direct to 2000’N/6700’W direct to1800’N/6200’W direct to 1800’N/6000’W direct to3830’N/6000’W direct to 3830’N/6915’W, thencecounterclockwise along the New York Oceanic CTA/FIRboundary to the Miami Oceanic CTA/FIR boundary,thence southbound along the Miami Oceanic CTA/FIRboundary to the point of beginning.8−7−4. LATERAL SEPARATIONIn accordance with Chapter 8, Offshore/OceanicProcedures, Section 4, Lateral Separation, apply thefollowing:a. 60 NM or 1 degree latitude between:1. Supersonic aircraft operating above FL 275.2. Aircraft which meet the MNPS and which:NOTE−This reduced lateral separation shall not be used if trackkeeping capability of the aircraft has been reduced for anyreason.North Atlantic ICAO Region8−7−1
