aircraft equipped with a single RVSM-compliant
altimeter to operate in DRVSM airspace - Add Atlantic and Gulf of Mexico High Offshore
airspace to correct RVSM airspace designation - Propose San Juan FIR to be RVSM airspace
7Program Coordination
- Coordination started with industry in Dec 2000
- FAA/Industry meetings held Feb and May 2001
- High level FAA management visibility through
Operational Evolution Plan (OEP) process
8Proposed Program Objectives
- Implement RVSM between FL 290 - 410 in
- Lower 48 states
- Alaska
- Gulf of Mexico airspace---where FAA provides air
traffic services - San Juan FIR and Florida-San Juan airspace
- Jan 20, 2005 target date---better AIRAC
(charting) date than Dec 2004
9NAS 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
10Reduced 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)
11Major Program Elements
- Aircraft and operators authorized by
Administrator or for - non-US operators/aircraft, the appropriate
foreign authority - Aircraft altimetry, auto-pilot, altitude alert
systems modified, as necessary, to RVSM standards - RVSM policy/procedures incorporated into
controller, pilot and dispatch programs - Air Traffic systems and programs revised
12Program Elements (cont.)
- Monitoring aircraft altitude-keeping observed
to confirm aircraft operating to standards - Ground and airborne monitoring systems used to
independently monitor aircraft performance - Safety Analysis based on accepted Collision
Risk Modeling practices
13RVSM Mandate
- When RVSM airspace implemented, RVSM
authorization required for operation in
designated airspace, with limited exceptions

15Safety and Benefits in Operations
- RVSM has proved safe and beneficial in areas
where previously implemented - Approx 6.5 million RVSM flights
- Approx 14.5 million RVSM flight hours
16FAA Continuity
- FAA specialists and supporting contractors have
played significant roles in national and
international program development and
implementation - Air Traffic
- Operations
- Certification
- Safety Analysis
17Current RVSM Regulations
- Part 91, Section 91.706 requires operator and
aircraft approval per Appendix G - Appendix G (RVSM Operations) 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
18Aircraft 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
19Equipment Tolerances
- Altitude Alert Threshold 300 ft
- Aircraft type certified after April 9, 1997
200 ft - Automatic Altitude Control System 65 ft about
acquired altitude - Aircraft certified prior to April 9, 1997 soft
altitude hold - /- 130ft allowed
20TCAS 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.
21Proposed Rule Changes
- New 91.180 add to Sub-part B to make Appendix
G applicable in domestic US, Alaska and Gulf of
Mexico - Appendix G Section 8, Designation of Airspace
list continental US, Alaska, Gulf of Mexico,
Offshore High and San Juan FIR in Section 8. - Effective dates and FLs not shown in rule
language - When finalized, will be announced in NOTAMS and
AIM
22Proposed Rule Changes
- Revise flight levels listed in 91.159 and 91.179
23Benefits 2005 - 2016
- Adds 6 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 - Steve Creamer will brief ATC benefits in detail
- ATC Flexibility
- Mitigate conflict points
- Enhance sector throughput
- Reduce controller workloade.g., reduce vectoring
24Costs 2002 - 2016
- 869 million costs
- Aircraft/operator approval
- 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 - Cost assessment being updated based on NPRM

25Airspace Use by Category
- 88.commercial flights
- 10.general aviation flights
- 2..military flights
26Implementation Date Factors
- 4,500 aircraft (33) already approved
- New airframes now delivered RVSM ready
- Project 90 of flights to be conducted by RVSM
approved aircraft by January 2005 timeframe - 393 m. first year fuel savings and ATC benefits
at stake - Aircraft Engineering Packages available for most
aircraft - Non-group/unique airframe process available
27Date Factors (cont).
- New 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, climb through RVSM FLs to operate at
FL 430 and above - Economic decision for some operators
- Unapproved Life guard and DoD aircraft to be
accommodated
28Operator/airframe factors
- Approx 13,500 DRVSM aircraft
- 4,500 (33) of US registered aircraft now RVSM
approved - 2,000 GA 2,500 commercial aircraft
- Approx 9,000 aircraft to be brought into
compliance - Key implementation factor is 90 RVSM
compliant aircraft flights projected for 1/2005
timeframe
29Conclusion
- DRVSM is a significant project in the NAS OEP
- Has proven safe and beneficial in other major
areas around the world
