4DRVSM Regulatory Basis
- New 91.180 published October 27, 2003 in
Sub-part B - Enables Appendix G to be applied in domestic US
on the planned implementation date - Appendix G Section 8 (Designation of Airspace)
lists international and domestic U.S. airspace
where RVSM may be applied - January 20, 2005 target implementation date
published in rule preamble - Handout 12-month Advance Notice published on
1/22/04 in Domestic/International NOTAM book
under Graphic Notices. See handout.
5Program Coordination
- Coordination started with industry in December
2000 - FAA/Industry meetings held in February and
- May 2001
- High level FAA management visibility through
Operational Evolution Plan (OEP) process
6 Program Objectives
- Target date/time January 20, 2005 0901 UTC
- Implement RVSM between FL 290 - 410 in
- Lower 48 states and Alaska
- Atlantic and Gulf of Mexico High Offshore
Airspace (including Houston and Miami Oceanic) - San Juan FIR
- Simultaneous implementation also planned for
Canadian Southern Domestic Airspace, Mexico and
- Caribbean and South American ICAO regions
7NAS Operational Evolution Plan
- www.faa.gov/programs/oep
- DRVSM is para ER-4 in NAS OEP
- Principle Office of Delivery (POD)
- Director, Flight Standards Service, AFS-1
8Reduced Vertical Separation Minimum
- 1,000 ft. vertical separation applied globally,
including domestic US, up to FL 290 for past 40
years - Special provisions of RVSM program enable
reduction of vertical separation from 2,000 ft.
to - 1,000 ft. between FL 290 - FL 410 (inclusive)
9Major Program Elements
- Operator Authorization. Aircraft and operators
authorized by Administrator or for non-US
operators/aircraft, the appropriate foreign
authority - Aircraft Equipage and Performance. Aircraft
altimetry, auto-pilot, altitude alert systems
modified, as necessary, to RVSM standards - Pilot, Controller, Dispatched Policy/Procedures.
RVSM policy/procedures incorporated into
controller, pilot and dispatch programs - Air Traffic systems and programs. Revised
10Program Elements (cont.)
- Monitoring Ground and airborne monitoring
systems used to independently assess aircraft
altitude keeping performance - Safety Analysis conducted in accordance with
accepted Collision Risk Modeling practices
11RVSM Mandate
- When RVSM airspace implemented, RVSM
authorization required for operation in
designated airspace, with limited exceptions - Exceptions discussed in Air Traffic briefing
- Policy/procedures for exceptions will be detailed
in notice to be published Domestic/International
NOTAM book and posted on FAA RVSM Documentation
Webpage

13Safety and Benefits in Operations
- RVSM has proved safe and beneficial in areas
where previously implemented - Approx 13 million RVSM flights
- Approx 24 million RVSM flight hours
- Accumulating approximately 5 million flights and
7 million flight hours per year world-wide
14FAA Continuity
- FAA specialists and supporting contractors have
played significant roles in national and
international program development and
implementation - Air Traffic
- Operations
- Certification
- Safety Analysis
15 RVSM Regulations
- 91.706 regulates RVSM operations outside the U.S.
- 91.180 regulates RVSM operations within the U.S.
- Both sections require operator and aircraft
approval per Appendix G - Appendix G (RVSM Operations) contains
detailed aircraft/operator approval criteria - Aircraft compliant with Appendix G are eligible
for RVSM operations world-wide - However, operators must adopt operational
policy/procedures in each new area of operations
16Aircraft Equipage forRVSM Operations
- !! Aircraft systems listed below must meet
tolerances shown on next slide - Two Independent Altimetry Systems
- One Automatic Altitude Control System
- One Altitude Alert System
- Transponder required by 91.215 for US operations
- ICAO transponder standards in Annex 6
17Equipment Tolerances
- Altitude Alert Threshold
- Aircraft type certificated prior to
4/9/1997 /-300 ft - Aircraft type certified after 4/9/1997 200
ft - Automatic Altitude Control System 65 ft about
acquired altitude - Aircraft certified prior to April 9, 1997 with
performance management systems soft altitude
hold /- 130 ft allowed
18TCAS Version 7.0
- Part 91 Appendix G, Section 2 amended in 2001 to
read -
- After March 31, 2002, unless otherwise
authorized by the Administrator, if you operate
an aircraft that is equipped with TCAS II in RVSM
airspace, it must be a TCAS II that meets TSO
C-119b (Version 7.0), or a later version.
19Parts 121, 125, 129 TCAS Reg Revision
- TCAS equipage reg revision not specific to RVSM
- Major elements of revisions
- 121.356, 125.224, 129.18 turbine-powered
aircraft of more than 33,000 lbs max take-off
weight require TCAS II equipage by 1/1/2005 - Effective May 1, 2003, initial TCAS II
installation or replacement must be TCAS II,
Version 7.0 - TCAS I remains acceptable for designated aircraft
categories - 135.180 not changed
20Benefits 2005 - 2016
- Adds six additional FLs between 290 - 410
- Fuel Savings and Operating Efficiency Benefits
- 2005 2016
- 5.3 billion
- 6/1 benefit/cost ratio
- 393m first year savings---with 2.0 annual
increase - Benefits to ATC operations
- Discussed in detail in AT briefing
21Costs 2002 - 2016
- 869 million costs
- Aircraft upgrade
- Downtime, if work not accomplished during
scheduled Mx - If TCAS II equipped, Version 7.0 upgrade
- Monitoring
- Air traffic system modification and controller
training costs - Pilot training
22Airspace Use by Category
- Airlines, Large Cargo...60
- Non-US (primarily large aircraft).............6
- Regional Jets........15.5
- Commercial and GA Business Jets..........17
- DoD...........1.5
23Key Implementation Factor
- Key implementation factor on January 20, 2005,
approximately 85-90 of flights now operating
between - FL 290-410 must be conducted by RVSM-compliant
aircraft - Intent is to avoid pushing down more than 10-15
of flights - Based on actual NAS traffic data, industry
surveys and RVSM Approvals Database, DRVSM Team
has projected that this goal will be met - DRVSM team is tracking this projection as program
progresses through 2004 - Unapproved aircraft can continue to operate
at/below FL 280 until they obtain RVSM authority
24Other Implementation Date Factors
- Current US RVSM Approvals Database Info.
- Database does not yet reflect all work known to
be underway on US operators fleets - 7,200 in database as RVSM-compliant (42)
- Approx. 4,800 business jets, 53 of US DRVSM
business jet fleet in database as RVSM-compliant - New airframes now delivered RVSM ready
- 393 m. first year fuel savings and ATC benefits
at stake - Aircraft Engineering Packages available for most
aircraft - Non-group/unique airframe process available
25Other Date Factors (cont).
- New cost-effective aircraft engineering solutions
available - Unapproved aircraft have options to
- Operate at FL 280 and below (fuel burn penalty,
but relatively short duration flights) - If capable and traffic permitting, climb through
RVSM FLs to operate at FL 430 and above - Economic decision for some operators
- Unapproved Life guard, DoD aircraft and aircraft
certification/development flights to be
accommodated
26Conclusion
- DRVSM is a significant project in the NAS OEP
- Has proven safe and beneficial in other major
areas around the world - The DRVSM Team will work with FAA organizations
and industry to continue progress toward
successful implementation
