JO 7110.65S 2/14/08
8-9-2 Pacific ICAO Region
(2) Reciprocal track aircraft - provided
that it has been positively established that the aircraft
have passed each other.
2. Distance verification shall be obtained from
each aircraft at least every 24 minutes to verify that
separation is maintained.
3. If an aircraft fails to report its position within
3minutes after the expected time, the controller shall
take action to establish communication. If communication
is not established within 8 minutes after the
time the report should have been received, the
controller shall take action to apply another form of
separation.
NOTEWhen
same track aircraft are at, or are expected to reduce
to, the minima, speed control techniques should be applied
in order to maintain the required separation.
d. Minima based on DME/RNAV:
Apply the following DME/RNAV minima in
Control1234H, Control 1487H and the Norton
Sound High Control areas to turbojet aircraft
established on or transitioning to the North Pacific
(NOPAC) Route System.
1. 30 NM between aircraft when DME reports or
radar observations are used to establish the distance,
otherwise at least 40 NM based on RNAV must be
applied; and
2. Unless both aircraft are radar identified, both
aircraft must provide DME/RNAV distance reports
via direct voice that indicates the appropriate
separation exists; and
3. Application of DME/RNAV separation
without direct voice communications may not
continue for more than 90 minutes; and
4. The preceding aircraft is assigned the same
or greater Mach number than the following aircraft;
and
5. Both aircraft shall be advised of the other
aircraft involved, including the distance relative to
the flights.
EXAMPLE-
“Maintain Mach point eight four, same direction traffic,
twelve o'clock, three five miles.”

8-9-4. LATERAL SEPARATION
In accordance with Chapter 8, Offshore/Oceanic
Procedures, Section 4, Lateral Separation, apply the
following:
a. Within areas where Required Navigation
Performance 10 (RNP-10) separation and procedures
are authorized, apply 50 NM to RNP-10
approved aircraft.
b. Apply 30 NM to RNP-4 approved aircraft
operating within airspace designated for RNP-4
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., Ocean21).
c. When aircraft operate within airspace where
composite separation and procedures are authorized,
apply the minimum specified in para 8-9-5,
Composite Separation Minima.
d. Apply 100 NM to aircraft not covered by
subparas a, b or c.
8-9-5. COMPOSITE SEPARATION MINIMA
Provide composite separation within the Central East
Pacific (CEP) and North Pacific (NOPAC) composite
route systems and where designated by facility
directive in the Pacific Organized Track System
(PACOTS) at and above FL 290 as follows:
a. 1,000 feet vertical separation; and
b. 50 NM lateral separation.
8-9-6. COMPOSITE SEPARATION
ALTITUDE ASSIGNMENT
a. Aircraft operating at or above FL300 in a
composite route system may be cleared at even flight
levels. Additionally, aircraft may be cleared at even
flight levels while joining, crossing, or leaving a
composite route system provided such aircraft
leaving the system are cleared to an appropriate odd
cardinal flight level when noncomposite vertical or
lateral separation is achieved.
b. Aircraft (operating at or above FL 300) leaving
a composite route system at an even cardinal flight
level do not have to be assigned an odd cardinal flight
level provided:

Pacific ICAO Region 8-9-3
1. The aircraft is being provided radar service;
and
2. The aircraft will be cleared for descent and
approach to an airport within the facility's domestic
FIR; and
3. There is an operational advantage.
c. Aircraft operating on unidirectional routes or
traffic flows may be assigned altitudes other than the
appropriate altitude for direction of flight provided
that 2,000 feet vertical separation is maintained
between aircraft operating on the same route.
8-9-7. COMPOSITE SEPARATION
APPLICATION
Provide composite separation in the CEP and the
North Pacific (NOPAC) composite route systems and
where designated by facility directive in the Pacific
