Standard except as prescribed by Federal Aviation Regulations (FAR).

INSTRUMENT FLIGHT RULES
Standard except as prescribed by FAR.
RVSM RULES -
1. REDUCED VERTICAL SEPARATION MINIMUM (RVSM)
a.
RVSM is implemented between FL290-410 (inclusive) in the following airspace: the airspace of the lower 48 states of the United States, Alaska, Atlantic and Gulf of Mexico High Offshore Airspace and the San Juan FIR. A chart showing the location of offshore airspace is posted on the DRVSM webpage http://www.faa.gov/ats/ato/drvsm/default.asp

b.
RVSM AUTHORIZATION - In accordance with Title 14 of the Code of Federal Regulations (14 CFR) Section 91.180, with only limited exceptions, prior to operating in RVSM Airspace, operators and aircraft must have received RVSM authorization from the responsible civil aviation authority. If the operator or aircraft or both have not been authorized for RVSM operations, the aircraft will be referred to as a "Non-RVSM" aircraft. Paragraph k. discusses ATC policies for accommodation of non-RVSM aircraft flown by the Department of Defense, Air Ambulance (Lifeguard) operators, foreign state governments and aircraft flown for certification and development. Paragraph l. contains policies for non-RVSM aircraft climbing and descending through RVSM Airspace to/from flight levels above RVSM Airspace.

c.
DRVSM FLIGHT LEVEL ORIENTATION SCHEME - Altitude assignments for direction of flight will follow a scheme of odd altitude assignment for magnetic courses 000°-179° and even altitudes for magnetic courses 180°-359° for flights up to and including FL410.

d.
SOURCES OF INFORMATION - The FAA RVSM website homepage can be accessed at: www.faa.gov/ats/ato/rvsm1.htm. The "RVSM Documentation" and "Domestic RVSM" web pages are linked to the RVSM homepage. “RVSM Documentation” contains guidance and direction for an operator to obtain aircraft

and operator approval to conduct RVSM operations. It provides information for DRVSM and oceanic and international RVSM Airspace.
e. TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEM (TCAS) EQUIPAGE - TCAS equipage requirements are contained in 14 CFR sections 121.356, 125.224, 129.18 and 135.189. Part 91 Appendix G does not contain TCAS equipage requirements specific to RVSM, however, Appendix G does require that aircraft equipped with TCAS II and flown in RVSM Airspace be modified to incorporate TCAS II Version 7.0 or a later version.
(AFFSA CL II NOTAM/AFFSA FIL 05-119)
NOTE:  If a non-RVSM aircraft receiving 2000’ altitude separation is operating in RVSM Airspace, there is no need for the aircraft to comply with the TCAS II requirement for version 7.0 or later.
f. FORMATION FLIGHTS -
(1)
RVSM separation standards will be utilized for formation flights, which consist of all RVSM approved aircraft. RVSM formation flights may file for a single altitude if all formation aircraft fly the assigned altitude, either offset laterally from each other or in trail. Non-standard formation flights (>100 feet vertical separation or >1 mile lateral or trail separation) or formations in which one or more aircraft will maneuver, should request an altitude block. Air Traffic Control may then apply RVSM separation standards between this altitude block and other RVSM aircraft (e.g. An RVSM formation flight is assigned FL320-FL330; ATC assigns other RVSM aircraft at FL310 and FL340).
