Operational Policy/Procedures for Reduced Vertical Separation Minimum (RVSM) in the
Domestic U.S., Alaska, Offshore Airspace and the San Juan FIR

4. Flight Planning into RVSM Airspace

a.

Operators that do not file the correct aircraft equipment suffix on the FAA or ICAO Flight Plan may be

denied clearance into RVSM airspace. Policies for the FAA Flight Plan are detailed in subparagraph c below.
Policies for the ICAO Flight Plan are detailed in subparagraph d.

b.

The operator will annotate the equipment block of the FAA or ICAO Flight Plan with an aircraft equipment

suffix indicating RVSM capability only after determining that both the operator is authorized and its aircraft are
RVSM

compliant.

1.

An operator may operate in RVSM airspace under the provisions of Part 91, Appendix G, Section 9,

without specific authorization and should file “/w” in accordance with paragraph d.

2.

An operator must get an OpSpec/MSpec/LOA when intending to operate RVSM outside U.S. airspace.

Once issued, that operator can file “/w” in accordance with paragraph d.

3.

An operator should not file “/w” when intending to operate in RVSM airspace outside of the U.S., if they

do not hold a valid OpSpec/MSpec/LOA.

c.

General Policies for FAA Flight Plan Equipment Suffix. Appendix 4, TBL 4

2, allows operators to indicate

that the aircraft has both RVSM and Advanced Area Navigation (RNAV) capabilities or has only RVSM
capability.

1.

The operator will annotate the equipment block of the FAA Flight Plan with the appropriate aircraft

equipment suffix from Appendix 4, TBL 4

2 and/or TBL 4

3.

2.

Operators can only file one equipment suffix in block 3 of the FAA Flight Plan. Only this equipment

suffix is displayed directly to the controller.

3.

Aircraft with RNAV Capability. For flight in RVSM airspace, aircraft with RNAV capability, but not

Advanced RNAV capability, will file “/W”. Filing “/W” will not preclude such aircraft from filing and flying
direct routes in en route airspace.

d.

Policy for ICAO Flight Plan Equipment Suffixes.

1.

Operators/aircraft that are RVSM

compliant and that file ICAO flight plans will file “/W” in block 10

(Equipment) to indicate RVSM authorization and will also file the appropriate ICAO Flight Plan suffixes to
indicate navigation and communication capabilities.

2.

Operators/aircraft that file ICAO flight plans that include flight in Domestic U.S. RVSM airspace must

file “/W” in block 10 to indicate RVSM authorization.

e.

Importance of Flight Plan Equipment Suffixes. Military users, and civilians who file stereo route flight

plans, must file the appropriate equipment suffix in the equipment block of the FAA Form 7233

1, Flight Plan,

or DD Form 175, Military Flight Plan, or FAA Form 7233

4, International Flight Plan, or DD Form 1801, DoD

International Flight Plan. All other users must file the appropriate equipment suffix in the equipment block of
FAA Form 7233

4, International Flight Plan. The equipment suffix informs ATC:

1.

Whether or not the operator and aircraft are authorized to fly in RVSM airspace.

2.

The navigation and/or transponder capability of the aircraft (e.g., advanced RNAV, transponder with

Mode C).

f.

Significant ATC uses of the flight plan equipment suffix information are:

1.

To issue or deny clearance into RVSM airspace.

2.

To apply a 2,000 foot vertical separation minimum in RVSM airspace to aircraft that are not authorized

for RVSM, but are in one of the limited categories that the FAA has agreed to accommodate. (See paragraphs
