Section 9. Reduced Vertical Separation
Minimum (RVSM)
6-9-1. GENERAL
a. RVSM
reduces the standard separation between FL290 and FL410 from
2,000 feet to 1,000 feet for those aircraft approved for
operation within these altitude strata. The six additional
altitudes provide the users fuel savings and operational
efficiencies while providing ATC flexibility, mitigation of
conflict points, enhanced sector throughput and reduced
controller workload for air traffic control operations.
b. RVSM
is applied in that airspace from FL290 through FL410 over the
domestic United States, Alaska, the Gulf of Mexico where the
FAA provides air traffic services, the San Juan FIR, across
international borders with Canada and Mexico, and the Pacific
and Atlantic Oceanic airspace controlled by the FAA. There are
two forms of RVSM airspace:
1. RVSM
Airspace. Use of the term RVSM airspace refers to the RVSM
exclusive environment. Aircraft operating in this airspace
must be RVSM approved.
NOTE-
1. The following non-RVSM aircraft are
exceptions to the exclusive RVSM airspace. However, access
will be on a workload-permitting basis:
a. DOD aircraft.
b. DOD-certified aircraft operated by NASA
(T38, F15, F18, WB57, S3, and U2 aircraft only).
c. MEDEVAC aircraft.
d. Aircraft being flown by manufacturers for
development and certification.
e. Foreign State aircraft.
2.
The following aircraft
operating within oceanic airspace or transiting to/from
oceanic airspace are excepted:
a. Aircraft being initially delivered to the
State of Registry or Operator;
b. Aircraft that was formerly RVSM approved
but has experienced an equipment failure and is being flown
to a maintenance facility for repair in order to meet RVSM
requirements and/or obtain approval;
c. Aircraft being utilized for mercy or
humanitarian purposes;
d. Within the Oakland, Anchorage, and Arctic
FIRs, an aircraft transporting a spare engine mounted under
the wing.
3. Aircraft not approved for RVSM
operations may transition through RVSM airspace to operate
above or below.
2. Transition
Airspace. Airspace where both RVSM aircraft and non-RVSM
aircraft may be accommodated at all altitudes and RVSM
approval is not required. Transition airspace connects
airspace wherein conventional separation is applied to RVSM
airspace. One thousand feet vertical separation can only be
applied between RVSM aircraft. Two thousand feet separation
must be applied between non-RVSM aircraft or whenever one of
the aircraft is non-RVSM.
c. Non-RVSM
exception aircraft may access RVSM airspace in one of the
following ways:
1. LOA:
Complies with a Letter of Agreement (LOA) for operations
within a single or adjacent ARTCCs.
2. File-and-Fly:
Files a flight plan and makes the initial request to access
RVSM airspace by requesting an ATC clearance.
d. Facilities
with RVSM airspace must:
1. Provide
guidance in the facility Standard Operating Procedures (SOP)
for managing non-RVSM flights.
2. Where
available, display the Center Monitor on the Traffic Situation
Display (TSD) in each area and the Traffic Management Unit (TMU).
This will aid in the coordination and decision making process
for approving non-RVSM flights.
6-9-2. FACILITY MANAGER RESPONSIBILITIES
a. Ensure
all facility directives are current to support RVSM.
b. Ensure
all LOAs, SOPs, and Sector Position Binders are current to
support RVSM.
c. Ensure
airspace is continually reviewed for impact of RVSM.
d. Ensure
all height deviations of 300 feet or more are recorded and
forwarded to the FAA Technical Center in Atlantic City, New
Jersey at NAARMO@faa.gov.

FAAO 7210.56, para 4-1-9, Invalid
Mode C Reporting.
6-9-3. OPERATIONS MANAGER-IN-CHARGE RESPONSIBILITIES
Responsibilities must include but not be limited to the
following:
a. Maintain
an operational awareness of RVSM impact specifically any non-RVSM
aircraft being worked within RVSM airspace.
b. Ensure
proper coordination is accomplished between the STMC/TMU and
the operations supervisors/controllers-in-charge regarding the
accommodation and handling of any non-RVSM aircraft.
c. Ensure, in conjunction with the
Traffic Management Officer, that monitor alert values are
addressed with RVSM impacts considered.
d. Ensure
the proper RVSM software is turned on.
6-9-4. FRONT-LINE MANAGER-IN-CHARGE/CONTROLLER-IN-CHARGE
RESPONSIBILITIES
Responsibilities must include but not be limited to the
following:
a. Maintain
an awareness of all operational impacts associated with RVSM,
specifically any non-RVSM aircraft currently within area
sectors or projected to be in sectors under his/her area of
responsibility.
b. Ensure
sector personnel have been properly briefed regarding any
known non-RVSM aircraft in or projected to be in sectors under
his/her area of responsibility.
c. Ensure
sector workload remains manageable when non-RVSM aircraft are
in or projected to be in sectors under his/her area of
responsibility.
d. Coordinate
all non-RVSM aircraft with operational supervisors/CIC as
appropriate, both internally and externally, to ensure the
aircraft is coordinated and accepted along its route of
flight.
e. Non-RVSM
Exception Flights Outbound from the U.S. The operational
supervisor/CIC from the last area to have communications and
operational control of the aircraft in the facility where an
aircraft departs RVSM airspace designated for U.S. air traffic
control, or exit facility, must coordinate with the
international point-of-contact in a timely manner.
f. Ensure
controllers at applicable sectors have their DSR MDM properly
aligned to display the RVSM indicator depicting those aircraft
that are non-RVSM.
6-9-5. NON-RVSM REQUIREMENTS
a. RVSM
approval is required for aircraft to operate within RVSM
airspace. The operator must determine that the appropriate
State authority has approved the aircraft.
b. DOD,
DOD-certified aircraft operated by NASA (T38, F15, F18, WB57,
S3, and U2 aircraft only), MEDEVAC, aircraft operated by
manufacturers for certification and development, and Foreign
State exception aircraft will be accommodated in RVSM airspace
on a workload permitting basis.
c. Within
oceanic airspace or transiting to/from oceanic airspace
aircraft being initially delivered to the State of Registry
or Operator, an aircraft that was formerly RVSM approved but
has experienced an equipment failure and is being flown to a
maintenance facility for repair in order to meet RVSM
requirements and/or obtain approval; an aircraft being
utilized for mercy or humanitarian purposes; and within the
Oakland, Anchorage, and Arctic FIRs, an aircraft
transporting a spare engine mounted under the wing will be
accommodated in RVSM airspace on a workload permitting
basis.
d. Non-RVSM
Exception Flights Inbound to U.S. The TMU at the facility
where an aircraft penetrates RVSM airspace designated for U.S.
air traffic control, or entry facility, receives the
coordination from an international point-of-contact advising
of an inbound non-RVSM exception. The TMU must coordinate with
the operational supervisor/CIC in a timely manner.
6-9-6. EQUIPMENT SUFFIX AND DISPLAY MANAGEMENT
RVSM aircraft will file a “W" in the equipment field
of an ICAO flight plan, or a suffix showing RVSM
capability in a domestic flight plan (/H, /W, /L, or /Z).
NAS automation shows nonRVSM aircraft with a
coral box around the fourth character in the altitude
segment of the data block. The conflict alert function
uses the flight plan indication of RVSM capability to
determine the appropriate separation standard to
apply.
6-9-7. MOUNTAIN WAVE ACTIVITY (MWA)
In
areas of known MWA, aircraft operators have been encouraged to
report encountering this weather event and the severity of its
impact. Operators may request assistance in the form of
reroutes, change of altitude, vectors, or merging target
procedures.
6-9-8. WAKE TURBULENCE AND WEATHER RELATED TURBULENCE
a. Domestic: Aircraft
experiencing turbulence can be anticipated to advise ATC and
request a clearance for mitigation in the form of vectors,
altitude change, or to fly an offset.
b. Oceanic: Aircraft
experiencing turbulence can be anticipated to advise ATC and
request a revised clearance. In instances where a revised
clearance is not possible or practicable, the aircraft may fly
a lateral offset not to exceed 2NM from the assigned route or
track. Advise ATC as soon as practical and return to the
assigned route when the offset is no longer required.
6-9-9. SUSPENSION OF RVSM
a. Domestic: RVSM
will not be suspended in domestic airspace. Should turbulence
or other weather phenomena require, separation can be
increased in a defined area and thoroughly coordinated
operationally.
b. Oceanic: Air
Traffic Service providers will consider suspending RVSM
procedures within affected areas when pilot reports of greater
than moderate turbulence are received. Within airspace where
RVSM procedures are suspended, the vertical separation minimum
between all aircraft will be 2,000 feet above FL290.
