  • Program Overview
  • June 3, 2003

2
Overview

  • Benefits and Costs
  • Implementation Date Factors Considered
  • Planned Rule Schedule

3
Access to Information
  • FAA RVSM and DRVSM website

  • Shows RVSM program status in airspace worldwide
  • RVSM Documentation page contains
  • RVSM Approval Checklist
  • Documents necessary to RVSM authorization
  • Manufacturer contacts
  • Listing of RVSM compliance docs (e.g., SB, STC)

4
Rule Schedule
  • May 10, 2002.NPRM published
  • Aug 8, 2002NPRM comment period closed
  • Feb 28, 2003..Supplemental NPRM published
  • Apr 14, 2003...SNPRM comment period closed
  • Administrator has signed Final Rule package and
    forwarded it to Dept. of Transportation
  • NAS Operational Evolution Plan shows FAA
    commitment to Jan 20, 2005 implementation date
  • Administrator will coordinate with DOT and OMB to
    expedite package

5
NPRM and SNPRM Comments
  • NPRM and SNPRM comments are available for review
    on DOT docket site http//dms.dot.gov
  • Simple Search on 12261

6
SNPRM Proposals
  • Withdraw proposal to allow part 91 turbo-prop
    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

7
Program 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

8
Proposed 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

9
NAS 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

10
Reduced 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)

11
Major 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

12
Program 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

13
RVSM Mandate
  • When RVSM airspace implemented, RVSM
    authorization required for operation in
    designated airspace, with limited exceptions

Safety 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

16
FAA Continuity
  • FAA specialists and supporting contractors have
    played significant roles in national and
    international program development and
    implementation
  • Air Traffic
  • Operations
  • Certification
  • Safety Analysis

17
Current 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

18
Aircraft 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

19
Equipment 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

20
TCAS 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.

21
Proposed 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

22
Proposed Rule Changes
  • Revise flight levels listed in 91.159 and 91.179

23
Benefits 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

24
Costs 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

Airspace Use by Category
  • 88.commercial flights
  • 10.general aviation flights
  • 2..military flights

26
Implementation 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

27
Date 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

28
Operator/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

29
Conclusion
  • DRVSM is a significant project in the NAS OEP
  • Has proven safe and beneficial in other major
    areas around the world
