NORTH AND SOUTH AMERICA - CNATRA - The US Navy

Airspace to Be Entered:
New York Oceanic CTA/FIR and
U.S. ARTCCs
3 To inform ATC and to key Ocean21 automation
that they have obtained RNP-10 or RNP-4 authorization and are
eligible for 50 NM lateral separation, operators shall:
(a) annotate ICAO Flight Plan Item 10
(Equipment) with the letters “R” and “Z” and . . .
(b) annotate Item 18 (Other Information)
with, as appropriate, “NAV/RNP10” or “NAV/RNP4” (no space
between letters and numbers).
4 50 NM lateral separation will only be applied to
operators/aircraft that annotate the ICAO flight plan in accordance
with this policy.
5 Operators that have not obtained RNP-10 or
RNP-4 authorization shall not annotate ICAO flight plan Item 18
(Other information) with “NAV/RNP10” or “NAV/RNP4”, but shall
follow the practices detailed in paragraph 4 of this notice.
NOTE: On the ICAO Flight Plan, letter “R” indicates that the
aircraft will maintain the appropriate RNP navigation specification
for the entire flight through airspace where RNP is prescribed.
Letter “Z” indicates that information explaining aircraft navigation
and/or communication capability is found in Item 18.
(4) In-flight Procedures within WATRS RVSM Airspace
(a) Before entering RVSM Airspace, the pilot should
review the status of required equipment. (See Appendix 4 of FAA
Interim Guidance 91-RVSM for pilot RVSM procedures). The
following equipment should be operating normally:
1 Two primary altimetry systems.
2 One automatic altitude-keeping device.
3 One altitude-alerting device.
(b) The pilot must notify ATC whenever the aircraft:
1 Is no longer RVSM compliant due to
equipment failure.
systems.
2 Experiences loss of redundancy of altimetry
3 Encounters turbulence that affects the
capability to maintain flight level. (See Appendix 5 of FAA Interim
Guidance 91-RVSM for pilot and controller actions in such
contingencies.)
(c) During cleared transition between levels, the
aircraft should not overshoot or undershoot the assigned flight
level by more than 150’ (45 meters).
(d) PILOT LEVEL CALL. Except in a radar
environment, pilots shall report reaching any altitude assigned
within RVSM Airspace.
(5) Height Deviation Reporting.
Required AFTN Addresses
Miami (KZMA) & NY Oceanic KZMAZQZX & KZWYZOZX
San Juan & NY Oceanic TZSUZRZX & KZWYZOZX
(a) Any deviation which is 300’ or more from the
assigned level in RVSM or RVSM Transition Airspace, whether
intentional or not, should be reported to the NAT CMA.
FLIGHT PLANNING 1-5
(b) Reporting these events to the NAT CMA is
accomplished using the form contained as Attachment 2 to the
NORTH ATLANTIC MNPSA OPERATIONS MANUAL (NAT MNPS
Operations Manual), which is available at http://www.natpco.org/mnpsa.htm.
It may be filed at the completion of flight or
it may be filed by the controlling ATC facility, as appropriate. It
should be sent to:
Separation Standards Group at the FAA William J. Hughes
Technical Center. Fax +01 609 485-5117.
North Atlantic Central Monitoring Agency. Email:

(6) Flight Planning Requirements
(a) The letter "W" shall be inserted in Item 10
(Equipment) of the ICAO standard flight plan to indicate that the
aircraft is RVSM approved aircraft.
(7) Procedures for Operation of Non-RVSM Compliant
Aircraft in RVSM Airspace.
(a) RVSM approved aircraft will be given priority for
level allocation over non-RVSM approved aircraft.
(b) The vertical separation minimum between non-
RVSM aircraft operating in the RVSM stratum and all other aircraft
is 2000’.
(c) CONTINUOUS CLIMB/DESCENT OF NON-
COMPLIANT AIRCRAFT THROUGH RVSM AIRSPACE. Non-RVSM
compliant aircraft may be cleared to climb to and operate above
FL410 or descend to and operate below FL290 provided that they:
1 Do not climb or descend at less than the
normal rate for the aircraft.
2 Do not level off at an intermediate level while
passing through the RVSM stratum.
(d) SPECIAL COORDINATION PROCEDURES FOR
CRUISE OPERATION OF NON-RVSM COMPLIANT STATE
AIRCRAFT IN RVSM AIRSPACE.
1 ATC notification of non-RVSM compliant state
aircraft (those aircraft used in military, custom, and police services
shall be deemed state aircraft) is accomplished through filing of an
ICAO flight plan. In Field 18 of the ICAO Flight Plan, include
"STS/APVD NONRVSM."
2 If approval status of non-RVSM state aircraft is
challenged by New York Oceanic, pilots of military aircraft should
state that they are operating a state aircraft in accordance with the
procedures set out in the WATRS RVSM NOTAM. Problems with
accommodation within WATRS RVSM Airspace should be reported
to AFFSA/XOP, DSN 857-2223.
3 Approval of all other (non-state) aircraft will be
in accordance with the WATRS RVSM NOTAM
(www.faa.gov/NTAP)
NOTE 1: New York Oceanic will coordinate non-RVSM status with
any affected adjacent FIR or facility.
NOTE 2: Approval means able to operate in the RVSM stratum.
Aircraft operating levels will be subject to Air Traffic Control.
