SERVICE INFORMATION LETTER
1. PURPOSE
This Service Information Letter (SIL) aims at informing the operators of the activities developed
at Airbus to implement the RVSM capabilities on the Airbus aircraft family.
This SIL will be updated in case of any changes on RVSM status and if RVSM activities on
Airbus aircraft are modified.
The aim of this SIL revision is to include drawings for RVSM marks around STANDBY STATIC
PORT (left and right) on A318/A319/A320/A321.
Changes in subject SIL are highlighted by a vertical revision bar in the left hand margin of the
respective page.
2. BACKGROUND
The goal of RVSM is to reduce the altitude vertical separation above flight level (FL) 290 from
the current 2000 ft (600m) minimum to 1000 ft (300m) minimum. This allows aircraft to fly more
optimum profiles, gain fuel savings and increase airspace capacity.
RVSM implementation in different parts of the world has progressed as follows:
a) North Atlantic Tracks / Minimum Navigation Performance Specification (NAT/MNPS):

Phase 1 from March 27, 1997 between FL330 and FL370
Phase 2 from October 8, 1998 between FL310 and FL390
Phase 3 from January 24, 2002 between FL290 and FL410.
b) Pacific:
From February 24, 2000 between FL290 to FL390.
c) New York FIR:

From November 1, 2001 for FL290 to FL410.
d) North America (called DRVSM, D for Domestic):

From January 20, 2005 between FL290 and FL410.
e) Canada:
Phase 1 (North) from April 2002 between FL290 and FL410
Phase 2 (South) from January 2005 between FL290 and FL410.
f) Europe:
From May 2000 Height monitoring program (2000-foot separation)
From January 24th, 2002 between FL290 and FL410.

3. DESCRIPTION
3.1. Technical objectives
The RVSM requirements, described in the FAA Interim guidelines 91-RVSM and in the JAA
Temporary Guidance Leaflet No6 Rev1, mention that the Altimetry System Error (ASE) of an
aircraft should not exceed +/- 200 feet (+/- 60 m).
Note: The ASE is defined as the difference between the actual pressure altitude and the displayed
altitude. The ASE is the average fleet altimetry system error of a given aircraft type.
3.2. Required equipment on aircraft
Two independent altitude measurement systems (2 ADR)

One SSR altitude reporting transponder (ATC transponder).
One Altitude alert system (FWC and MWC for A300 B2/B4)
One Autopilot with automatic altitude control capabilities.
4. AIRBUS SOLUTIONS
4.1. Airbus RVSM certification methodology – Principle
Airbus certified every aircraft model as a group. Today, 5 groups exist:
- A300B2/B4
- A310/A300-600
- A318/A319/A320/A321
- A330/A340/A340-500/-600
- A380
Operators should refer to the “aircraft group” category in their application to RVSM.
4.2. Guidelines to obtain RVSM certification
The RVSM compliance is now basic in production from the following MSN:
o A300-600 (GE + PW): from MSN 755

o A310 (GE): from MSN 702
o A318: All MSNs
o A319: from MSN 1159
SIL NUMBER: 34-064

PAGE: 3 of 22
DATE: Dec 22/1995
AIRBUS
o A340: from MSN 114 (All A340-500/-600)

o A380: All MSNs
Consequently, no additional work is required for the operators to comply with RVSM
regulations.
Concerning the other aircraft delivered before the MSN mentioned in this paragraph, including
all A300 B2/B4, a SB package is required to get RVSM compliance.
Details on the SB package to apply on each aircraft are described in paragraph 5.
In that case, two steps are required to get the certification:

- To follow Airbus SB directives
- To submit SB results to local Airworthiness Authorities
4.2.1. Technical certification through Airbus Service Bulletins
The applicable Airbus Service Bulletins will be validated for a given aircraft or fleet in response
to the RMO acceptance by the customer.
A summary of RVSM modifications for the Airbus programs is provided in Appendix 1.
RVSM Airbus Service Bulletins lead to the update of the publications c), d), e) and f) listed in
“References” paragraph (page 1).
Embodiment of RVSM Service Bulletin requires three steps:
1. Inspection of the aircraft skin waviness.
2. Precision ground check of the instruments.
3. Survey of the Altitude accuracy during a revenue flight. Refer to the appendixes for the
tables.
Note: In order to relieve the airlines from completing such an additional flight survey, Airbus
collects the Altitude-Airspeed performances achieved during the acceptance Flights. These data
are systematically recorded since the RVSM introduction (mid 1996 in a dedicated RVSM form
which is included in the Production Aircraft Test Completion Certificate (PATCC)) for the
aircraft with the RVSM modification validated in production.
This PATCC form can be used as a substitute to the operational survey required in the RVSM
SBs. The airlines have to copy the recorded values from PATCC form to the table attached to this
SIL, and further present them to the Airworthiness Authorities to get the RVSM operational
approval.
4.2.2. Operational approval
Operators must apply for RVSM approval for each individual aircraft to their relevant state
authority.
The aircraft Altitude-Airspeed performances recorded earlier in the SBs or PATCC forms must be
presented to the local authorities at that stage.
SIL NUMBER: 34-064

PAGE: 4 of 22
DATE: Dec 22/1995
AIRBUS
Upon local Airworthiness Authorities request, operators could be requested to demonstrate

Altitude-Airspeed performances thanks to a flight over specific Height Monitoring Unit (HMU)
or by using a GPS Monitoring Unit (GMU) which is an independent height monitoring system
taken onboard the aircraft.
For each operator, a sampling of aircraft belonging to the same “category” will need to be
checked. Refer to the “Minimum Monitoring Requirements Chart”.
To comply with that requirement, the operators will have to do this flight no later than six months
following the RVSM approval (refer to the height monitoring policy of the relevant authority)
over one of the HMU of the relevant authority.
Refer to the contact list in the next chapter to look for above mentioned document/form and
organise this monitoring.

4.3. Maintenance requirements
SIL NUMBER: 34-064

PAGE: 5 of 22
DATE: Dec 22/1995
AIRBUS
An update of the MSG-3 analysis has confirmed that neither scheduled maintenance tasks, nor
specific recommendations on RVSM involved parts (Air Data channel, autopilot, structure) are
needed on any aircraft type to hold their RVSM capability.
However, as far as the skin waviness is concerned, the Structural Repair Manual (SRM) of each
aircraft type has been updated to reflect the structural tolerance needed to meet the RVSM
requirements (In case of structural repair in the area of the Air Data probes).
Note: The RVSM SB package proposed by Airbus requires a one-time check (visual only) of the
skin waviness. If the visual control of the skin waviness is satisfactory, no further ground check is
required. If not, it is necessary to control the skin waviness tolerances using specific tooling. The
tooling is reflected in the RVSM Service Bulletin package and is loaned by Airbus on request
4.4. Visual inspection around the static probes
During the pre-flight check (refer to the FCOM chapter “Exterior Inspection”), it is requested to
inspect the fuselage around the static ports (left and right sides).
In order to help the operators to determine easily the area to be inspected, Airbus proposes to
draw on the fuselage some red marks as defined below (corners of a square).
Note: These marks are for information only and aim at easing the pre-flight check.
In addition, they are not mandatory to achieve the RVSM certification. In case of scratches or
dents around the static ports, the only applicable documentation is the SRM ATA 53.

The Nord-Micro DADC installed on the A310 PW will not be updated with new SSEC
correction laws (unit no longer manufactured).
To be RVSM compliant, Nord-Micro DADC must be replaced by the Honeywell
DADC -914.
Airbus Service Bulletin:

o A310 (PW): MOD 11468, SB 34-2112 issued May 14/1996.
Note: For PW equipped aircraft the RVSM Service Bulletin calls the SB 34-2114 covering the
Honeywell DADC (-914) installation.
5.3. A318/A319/A320/A321
The type certification was originally granted for RVSM operation with three ADIRUs. Further to
findings that the ADIRU #3 may fail to meet the RVSM criteria at high speed (Mach 0.82), the
type certification was granted for operation with ADIRU #1 and ADIRU #2 only. Refer to OIT
999.0019/00 Rev 1.
Then, an aircraft can be certified RVSM on 2 or 3 ADIRU, according to embodied modifications.
Solutions have been defined to extend the RVSM certification on three ADIRU:
- Structural modification on static port n°3: mod 28913
- Pitot relocation: mod 25490 (retrofit) and mod 25570 (production)
- Trim correction law ADIRU implementation: mod 31038
Note: A318 aircraft is not impacted by the above information. The A318 is basically RVSM
compliant with 3 ADIRUs.
5.3.1. Certification with two ADIRU systems
A319, A320, A321 comply with the RVSM requirement using two main ADR systems (ADIRU1
and ADIRU2) without any additional system modification (Paper work only).
3 solutions to get RVSM certification with 2 ADIRUs are possible:
• Aircraft with Pitot probe 1 not relocated: Mod 25910; SB A320-34-1115, or
• Aircraft with Pitot probe 1 relocated in production as per mod 25570 but without,
o Mod 25861 for A319/A320 (SB 34-1137 for retrofit; RVSM without restrictions)
o Mod 25952 for A321 (SB 34-1137 for retrofit; RVSM without restrictions)
o Mod 25910; SB A320-34-1115, or
• Aircraft with Pitot probe 1 relocated as per mod 25570 for production or Mod 25490 /
SB34-1122 (retrofit): Mod 27714; SB A320-34-1172
SIL NUMBER: 34-064

PAGE: 11 of 22
DATE: Dec 22/1995
AIRBUS
The modification 27714 (RSVM using two main ADR systems ADR1 & ADR2) is also validated
from following MSNs:
• A319 MSN 1159
• A320 MSN 1156
• A321 MSN 1174
Finally, operators who rejected the MOD for RVSM compliance in production,
o Mod 28685 on A319/A320
o Mod 28686 on A321
shall contact Airbus Upgrade Services and apply RFC/RMO process with SB 34-1115 for RVSM
on 2 ADRs.
5.3.2. Certification with three ADIRU
5.3.2.1. Production aircraft
A structural modification (mod. 28913) of the static port #3 area has been created to restore
RVSM performances in terms of altitude computed by ADIRU n° 3.
This modification is embodied on all new aircraft from the following ranks:
• A318 all MSN
• A319 MSN 1378
• A320 MSN 1361
• A321 MSN 1399
This structural modification is not proposed for retrofit (several days of work on aircraft would be
required for its implementation).
In addition, a global modification (mod 31528) has been created (paper work only) to restore the
RVSM compliance of the ADR3 on aircraft fitted with the structural modification (mod 28913).
For aircraft already delivered with the structural mod 28913 but without mod 31528, Airbus
SB A320-34-1252 has been issued and covers mod 31528.
To be RVSM compliant with 3 ADIRUs, all A320 family aircraft (including A318) are
manufactured with mod. 31528 / SB A320-34-1252 from the following MSN:
• A318 all MSN
• A319 MSN 1604
• A320 MSN 1564
• A321 MSN 1607
5.3.2.2. In-service aircraft
RVSM capability on ADIRU n° 3 can be restored thanks to correction laws implemented on new
ADIRU standards and activated by pin programming on ADIRU only. This capability is available
from the following ADIRU standards:
SIL NUMBER: 34-064

DATE: Dec 22/1995
AIRBUS
- Honeywell 4 MCU ADIRU PN HG2030AC11 (SB A320-34-1240), PN HG2030AD11

(SB A320-34-1249) and subsequent.
- Northrop Grumman (ex-Litton) ADIRU PN 465020-0303-0314 (SB A320-34-1245) and
subsequent.
Note 1: Aircraft fitted with ADIRU 10 MCU (PN HG1150AC0X) are no RVSM capable on
ADIRU 3, but can still be RVSM compliant with 2 ADIRU.
Note 2: When the Pin programming is applied on ADIRU 3, the interchangeability on position 3
is possible according to the conditions mentioned in IPC 34-12-34 and SIL 34-070.
a) Prerequisite to the certification on three ADIRUs:
The pitot probe #1 must be relocated according to the embodied modification:

o Mod 25570 (production): validated as follows:
- A319: from MSN 663
o Mod 25490/SB A320-34-1122 (retrofit): effective for MSN lower than the above
mentioned.
Note: When the structural modification is applied (mod 28913) from production, no specific pin
programming is required on ADIRU3 to be RVSM compliant. Consequently, as far as
the AMM tasks are concerned, the test corresponding to a trim of "0Ft" must be used.

APPENDIX 2
RVSM SURVEY OF AIR DATA PARAMETERS
1. In the course of a revenue flight, above FL300,
- A300B ........................................: At Mach 0.80 +/- 0.02

- A310/A300-600..........................: At Mach 0.78 +/- 0.02
- A318/A319/A320/A321 .............: At Mach 0.78 +/- 0.02
- A330/A340.................................: At Mach 0.82 +/- 0.02.
2. Make sure the aircraft is in clean configuration (S/F retracted).
3. Make sure the flight is symmetrical (No sideslip) and stabilized in a quiet atmosphere.
4. Survey the altitude, airspeed, and mach of the main and standby Air Data systems at 3 different flight
levels between FL300 and FL410.
Note: The recording of the points can be performed in one shot during the same flight or during 3
different flights at 3 different flight levels.
5. Fill in the RVSM form (See appendixes) with the altitude, airspeed, and mach surveyed in Step 4.
6. Compare the recorded values with the authorized tolerances shown in the tables.
If at least one of the values recorded at 3 different flight levels is incorrect, refer to the applicable
TSM (Altitude differences) or SRM (skin waviness) procedures.
7. If all the recorded values meet the RVSM tolerances, the table shall be further presented to the
airline’s local Airworthiness Authorities to gain the RVSM operational approval.
Note: As mentioned in paragraph § 4.4.2, aircraft for which the PATCC shows altitude values
within the frame of RVSM tolerances, the revenue flight is not mandatory.
Indeed, PATCC values can be used to get approval from Airworthiness Authorities.
