RVSM Documentation Webpage

• Documents Applicable to All RVSM Approvals
• 91-RVSM Appendix 4 - practices/procedures
  applicable to all RVSM operations
• 91-RVSM Appendix 5 - practices/procedures
  applicable to Oceanic RVSM operations
• Master Minimum Equipment List for RVSM
• TCAS II, Version 7.0 Modifications
• Large Transport Aircraft Documents
• Dispatcher Guidance for RVSM Operations

Documentation Webpage (cont.)

• DRVSM area of operations operational
  practices/procedures are under development
• Guidance on wake turbulence and mountain wave
  events
• Phraseology
• In-flight aircraft system malfunctions
• Contingency procedures (e.g., engine failure) -
  applicability of parts of Appendix 5 oceanic
  material to domestic ops

4
Area of Operations SpecificPolicy/Procedures

• North Atlantic, West Atlantic, Asia/Pacific and
  Europe RVSM Documentation sections contain
  applicable
• Contingency Procedures
• Weather Deviation Procedures
• Track Offset Procedures
• Flight planning policies

5

• 91-RVSM Appendix 4 Practices/Procedures

6
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

7
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

8
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

9
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
• Cross check primary altimeter agreement within
  200 ft
• Normally, altimeter controlling autopilot should
  provide source for transponder reporting to ATC

10
Post flight

• Annotate maintenance documents
• See Appendix 4 paragraph 6

11

• Miscellaneous Notes

12
Sample Pilot Bulletin

• AFS-400 will develop and distribute a sample
  pilot bulletin to
• address policy/procedures specific to domestic
  US RVSM operations

13
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

14
Wake Turbulence

• In RVSM airspace, aircraft are gear-up/flaps-up
  and at cruise speed
• 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
