  • 8-7-4. LATERAL SEPARATION

    In accordance with Chapter 8, Offshore/Oceanic Procedures, Section 4, Lateral Separation, apply the following:

    1. 23 NM to approved aircraft (at a minimum, RNP 4, RCP 240, and RSP 180) operating within airspace designated for 23 NM lateral separation when direct controller/pilot communications via voice or Controller Pilot Data Link Communications (CPDLC), and the required ADS-C contracts are maintained and monitored by an automated flight data processor (e.g., ATOP).
    2. 50 NM between Required Navigation Performance (RNP 4 or RNP 10) approved aircraft that operate in the New York Oceanic CTA/FIR or the San Juan Oceanic CTA/FIR or the Atlantic portion of the Miami Oceanic CTA/FIR.

      NOTE: This reduced lateral separation must not be used if track-keeping capability of the aircraft has been reduced for any reason.

      1. Operate on routes or in areas within WATRS, the San Juan CTA/FIR or the Atlantic portion of the Miami Oceanic CTA/FIR; or
      2. Operate in the New York Oceanic CTA/FIR outside of WATRS.

      NOTE: This reduced lateral separation must not be used if track-keeping capability of the aircraft has been reduced for any reason.

    3. 60 NM or 1 degree latitude between:
      1. Supersonic aircraft operating above FL 275.
      2. Aircraft which have MNPS or NAT HLA authorization and which:
        1. (a) Operate within NAT HLA; or
        2. (b) Are in transit to or from NAT HLA; or
        3. (c) Operate for part of their flight within, above, or below NAT HLA.

      NOTE: This reduced lateral separation must not be used if track-keeping capability of the aircraft has been reduced for any reason.

    4. 90 NM or 1 and 1/2 degrees latitude between aircraft not approved for RNP 4 or RNP 10 and which:
      1. Operate on routes or in areas within WATRS, the San Juan CTA/FIR or the Atlantic portion of the Miami CTA/FIR;
      2. Operate between points in the U.S. or Canada, and Bermuda;
      3. Operate west of 55° West between the U.S., Canada, or Bermuda and points in the Caribbean ICAO Region.
    5. 120 NM or 2 degrees latitude between aircraft not covered by subparagraphs a, c or d above.

      NOTE: Tracks may be spaced with reference to their difference in latitude, provided that in any interval of 10 degrees of longitude the change in latitude of at least one of the tracks does not exceed 3 degrees when operating south of 58° North.
