  West Atlantic, Asia/Pacific and Europe RVSM
  Documentation sections contain applicable
• Contingency Procedures
• Weather Deviation Procedures
• Track Offset Procedures
• Flight planning policies
• DRVSM section being updated as documents are
  finalized

DRVSM Operational Policy/Procedures

• Draft DRVSM AIM material distributed for comment
  as a Document Change Proposal (DCP)
• Draft includes
• Basic policy discussed in this seminar
• Guidance on wake turbulence and mountain wave
  events
• Phraseology
• In-flight aircraft system malfunctions
• Contingency procedures (e.g., engine failure) -
  applicability of Appendix 5 oceanic material to
  domestic ops

Timing for DRVSM Operational Policy

• Draft AIM Table of Contents is posted on RVSM
  Documentation Webpage
• Feb 04.post draft AIM Chapter 4 (Air Traffic
  Control) Section 5 (DRVSM) on RVSM Docs Webpage
  after reviewing DCP comments
• May 04.post final AIM material on RVSM Docs
  Webpage along with Sample Pilot Bulletin
• Feb 05.publish Chapter 4, Section 5 in AIM

• 91-RVSM Appendix 4 Practices/Procedures

7
Flight Planning

• Verify aircraft is RVSM compliant
• Annotate flight plan with block letter W to
  show RVSM approval
• Check forecast and reported weather conditions
• Check MEL requirements
• Check RVSM operating limitations, if applicable

8
Pre-flight at the Aircraft

• Review maintenance logs and forms
• Check MEL required systems operational
• During external inspection, check condition of
  fuselage around pitot static sources
• Compare altimeters to known ground elevation
• Difference not to exceed specified limits

9
Procedures Prior to RVSM Airspace Entry

• The following equipment should be operating
  normally
• Two primary altitude measurement systems
• One automatic altitude-control system
• One altitude-alerting device
• Transponder operating per existing requirements

10
Enroute Procedures

• Comply with RVSM operation limitations, if
  applicable
• Fly aircraft at cleared flight level
• Control altitude transitions - over/undershoot
  not to exceed 150 ft.
• In cruise, fly with automatic altitude control
  engaged except as required to trim aircraft or to
  disengage for turbulence
• Altitude alert should be operational

11
Enroute Procedures (cont.)

• At approximately one hour intervals, cross check
  primary and stand-by altimeters
• Check primary altimeter agreement within 200 ft.
• At least initial cross check should be recorded
• Normally, altimeter controlling autopilot should
  provide source for transponder reporting to ATC

12
RVSM Aircraft System Malfunction Enroute

• The following pilot actions are posted in the
  draft AIM material to be finalized in May
• Scenario Failure of Auto-pilot, Altitude
  Alerter or All Primary Altimeters
• Pilot will
• Contact ATC and state Unable RVSM Due to
  Equipment
• Request clearance out of RVSM airspace---unless
  operational situation dictates otherwise

13
RVSM Aircraft System Failure Enroute

• Scenario One Primary Altimeter Remains
  Operational
• Pilot will
• Cross check stand-by altimeter
• Notify ATC of operation with single primary
  altimeter
• If unable to confirm primary altimeter accuracy,
  follow actions for failure of all primary
  altimeters

14
Post flight

• Annotate maintenance documents
• See Appendix 4 paragraph 6

15

• Miscellaneous Notes

16
Flight Plan Equipment Suffix

• Currently filing letter W in either the ICAO or
  FAA Flight Plan shows ATC that operator/aircraft
  are authorized for RVSM operations
• For FAA Flight Plan, considering adoption of
  letter Q to show authorization for RVSM and
  RNAV or RNP
• We will keep operators advised as the policy
  develops

17
TCAS V7.0

• Traffic Alert threshold 850 ft.
• Corrective RA threshold 600 ft.
• Preventive RA threshold 700 ft.
• Operating Recommendations
• Operate TCAS in TA/RA mode during RVSM operations
  including transition areas
• Limit climb and descent rates to 1,000 fpm when
  operating within 5 nm and 2,000 ft vertically of
  other aircraft

18
Wake Turbulence

• In RVSM airspace, wake turbulence generally found
  to be moderate or less
• Wind direction determines probability of
  encounter
• Will take advantage of Australian and European
  continental experience to update pilot guidance
  for DRVSM
