5Interim Guidance 91-RVSM (cont.)
- Manufacturers and Approved Design Organizations
use part 91 Appendix G and supporting 91-RVSM
guidance to - Gain Aircraft Certification Office approval of
RVSM Data Package containing data and analysis
justifying RVSM Airworthiness Approval for group
and non-group aircraft - Gain ACO approval, for in-service aircraft, of
SB, SL or STC to be applied by operators to bring
aircraft into RVSM compliance (i.e., required
inspections and/or modifications) - Gain ACO approval, for new-build aircraft, of
statements of RVSM eligibility in Airplane Flight
Manual or Type Certificate Data Sheet (TCDS)
6Aircraft Approval Requirements
- Aircraft may be approved to RVSM requirements as
Group aircraft or Non-group aircraft - Must meet Appendix G minimum aircraft equipage
requirements - Required aircraft avionics systems must meet
Appendix G performance tolerances - Continued airworthiness instructions must be
provided, if found necessary
7Aircraft Approved for World-wide Operations
- RVSM compliant aircraft are eligible for RVSM
operations world-wide - FAA and JAA aircraft approval criteria
established for world-wide approvals - Assumptions such as high density traffic used in
criteria development
8Approval Objective
- The objective of airworthiness approval for
RVSM operations is to demonstrate that the design
and manufacture of the aircraft, its systems, and
their installation can meet the performance
criteria necessary for RVSM operation, as defined
in Part 91 Appendix G.
9Basis of RVSM Airworthiness Approval
- The altimetry system performance for any aircraft
is governed by the appropriate certification
requirements - i.e., FAR/JAR 25.1325, "Static Pressure Systems.
- RVSM airworthiness approval is in addition to the
requirements defined by the aircraft's
certification basis.
10Airworthiness Approval
- Airworthiness authorities (e.g., ACOs) have
approved RVSM data packages for most aircraft
types. - The data packages
- Identify the approved aircraft type or group
- Detail how the manufacturer has verified the
altimetry system performance
11Minimum Equipment for RVSM Operations
- Two independent altitude measurement systems
- Each system should be composed of the following
elements - Cross-coupled static source system
- Static source error correction (SSEC), if needed
to meet the ASE requirements -
- An altitude alert system
- An automatic altitude control system
- Note Altitude reporting transponder equipage
required by 91.215.
12Equipment Tolerances(Reference Appendix G)
- ASE Requirements Basic Envelope Full
Envelope - Group Aircraft Mean ASE of the group lt80 ft
(25m) lt120 ft (37m) - (pre April 1997) Mean ASE 3SD lt200 ft
(60m) lt245 ft (75m) - Group Aircraft N/A
Mean ASE lt80 ft (25m) - (post April 1997) N/A
Mean ASE 3SD lt200 ft (60m) - Non-group Aircraft Residual static source error
lt200 ft (60m) - worst case avionics lt160 ft (50m)
- ALTITUDE ALERT LIMIT 300 ft Altitude
Deviations - Aircraft applying for type certification after
April 1997 200 ft - AUTOMATIC ALTITUDE CONTROL SYSTEM 65 ft (20m)
about acquired altitude Note For aircraft type
certified prior to April 1997, FMS/PMS system
with 130 ft variations allowed
13Definition of Flight Envelopes
FAA/JAA documents evaluate ASE requirements
against the basic flight envelope and the full
envelope
Full RVSM Envelope
14Definition of Flight Envelopes
- Basic RVSM Envelope
- Same as full envelope except upper Mach boundary
- Upper Mach boundary not less than long range
cruise plus 0.04 Mach - Note Basic envelope is not applicable to post
April 1997 group aircraft
15TCAS II, Version 7.0
- Appendix G amended in December 2001
- "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. - Applicable to US-registered aircraft, not FAA
controlled oceanic airspace
16Operator Documents
- For operator action, aircraft RVSM compliance
documents have taken the form of - For In-service Aircraft
- Manufacturers Service Bulletins and Letters
- Supplemental Type Certificates
- Aircraft Service Change for Gulfstream aircraft
- For New-production aircraft manufactured in
compliance with Appendix G - Statement of Compliance in AFM and/or TCDS
- All documents approved by Aircraft Certification
Offices
