2. Supersonic aircraft operating at or above
FL450 not covered in subpara 1 above.
NOTEThis
reduced lateral separation shall not be used if track
keeping capability of the aircraft has been reduced for any
reason.
3. Aircraft which meet the MNPS and while
operating in the New York oceanic CTA/FIR which
are in transit to or from NAT MNPS airspace.
b. 90 NM between aircraft operating:
1. Within WATRS;
2. West of 55 West between the U.S., Canada,
or Bermuda and points in the Caribbean ICAO
Region.
c. 100 NM between aircraft operating west of
55West not covered by subparas a or b above.
d. 120 NM between aircraft operating east of
55West.
8-8-5. VFR CLIMB AND DESCENT
a. In the Houston, Miami, and San Juan CTAs, IFR
flights may be cleared to climb and descend in VFR
conditions only:
1. When requested by the pilot; and
2. Between sunrise and sunset.
b. Apply the following when the flight is cleared:
1. If there is a possibility that VFR conditions
may become impractical, issue alternative instructions.
2. Issue traffic information to aircraft that are
not separated in accordance with the minima in this
section.

Pacific ICAO Region 8-9-1
Section 9. Pacific ICAO Region
8-9-1. APPLICATION
Provide air traffic control services in the Pacific
ICAO Region with the procedures and minima
contained in this section except when noted
otherwise.
8-9-2. VERTICAL SEPARATION
Provide vertical separation in accordance with
Chapter 4, IFR, Section 5, Altitude Assignment and
Verification, except when aircraft operate within
airspace where composite separation and procedures
are authorized, apply the minima specified in
para8-9-5, Composite Separation Minima.
8-9-3. LONGITUDINAL SEPARATION
In accordance with Chapter 8, Offshore/Oceanic
Procedures, Section 3, Longitudinal Separation,
apply the following:
a. Minima based on time:
1. 15 minutes between aircraft; or
2. 10 minutes between turbojet aircraft whether
in level, climbing or descending flight, provided that
the aircraft concerned follow the same track or
continuously diverging tracks until some other form
of separation is provided; or
3. The prescribed minima in accordance with
para 8-3-3, Mach Number Technique.
4. Reciprocal track aircraft - Where lateral
separation is not provided, vertical separation shall be
provided at least 10 minutes before and after the time
the aircraft are estimated to pass or are estimated to
have passed.
b. Minima based on distance using Automatic
Dependent Surveillance - Contract (ADS-C):
1. Apply the minima as specified in TBL 8-9-1,
ADS-C Criteria, between aircraft on the same track
within airspace designated for Required Navigation
Performance (RNP), provided:
(a) Direct controller/pilot communication via
voice or Controller Pilot Data Link Communications
(CPDLC) is established, and
(b) The required ADS-C periodic reports are
maintained and monitored by an automated flight
data processor (e.g., Ocean21);
TBL 8-9-1
ADS-C Criteria
Minima RNP Maximum ADS-C
Periodic Reporting
Interval
50 NM 10 27 minutes
50 NM 4 32 minutes
30 NM 4 14 minutes
2. Aircraft on reciprocal tracks may be cleared
to climb or descend to or through the altitude(s)
occupied by another aircraft provided that:
(a) An ADS-C position report on at least one
of the aircraft has been received beyond the passing
point, and
(b) The aircraft have passed each other by the
applicable separation minimum.
NOTEOcean21
has been designed to check for the above criteria
prior to allowing the minima to be provided.
3. When an ADS-C periodic or waypoint
change event report is overdue by 3 minutes, the
controller shall take action to obtain an ADS-C
report.
4. If no report is received within 6 minutes of the
time the original report was due, the controller shall
take 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 or
reciprocal track that meet the requirements for and
are operating within airspace designated for RNP-10
operations provided:
(a) Direct controller/pilot communication via
voice or CPDLC is maintained; and
(b) Separation is established by ensuring that
at least 50 NM longitudinal separation minima exists
between aircraft positions as reported by reference to
the same waypoint.
(1) Same track aircraft - whenever possible
