Reduced Vertical Separation Minimum (RVSM) airspace is any airspace or route between FL 290
and FL 410 (inclusive), where aircraft are vertically separated by 1 000 ft, instead of 2 000 ft. The
A340 system design complies with the design criteria of the JAA Information Leaflet N° 6, and the
FAA 91-RVSM Interim Guidance Material for RVSM operations. The statement of RVSM capability is
also indicated in the AFM.
GENERAL

Reduced Vertical Separation Minimum (RVSM) airspace is any airspace or route between FL 290
and FL 410 (inclusive), where aircraft are vertically separated by 1 000 ft, instead of 2 000 ft. The
A330 system design complies with the design criteria of the JAA Information Leaflet N° 6, and the
FAA 91-RVSM Interim Guidance Material for RVSM operations. The statement of RVSM capability is
also indicated in the AFM.
OPERATIONAL APPROVAL
Applicable to: ALL
The above capability statement does not constitute an approval to fly RVSM. Operational approval
is to be granted by the Operator’s national authorities, after assessment of the airline’s capability to
meet RVSM requirements. The above-mentioned JAA and FAA documents also cover requirements
to obtain operational approval.
REQUIRED EQUIPMENT/FUNCTIONS FOR RVSM
Applicable to:
RVSM regulations require the following equipment/functions to be operative :
‐ 2 ADRs + 2 DMCs
‐ 1 transponder
‐ 1 Autopilot function
‐ 2 PFD functions (for altitude indication)
‐ 1 FCU channel (for altitude target selection and OP CLB/OP DES mode engagement)
‐ 1 FWC (for altitude alert function)
Note: In case of an FCU B+C channel failure, the autopilot function is lost (Refer to 99 Duref
Cible FCOM). RVSM operation is, consequently, not allowed.

PROCEDURES
Applicable to: ALL
The SOPs and the ABN and EMER procedures apply. In addition, flights in RVSM airspace must be
completed by the following :
FLIGHT PREPARATION
The crew must pay particular attention to conditions that may affect operation in RVSM airspace.
These include, but may not be limited to :
‐ Verifying that the airframe is approved for RVSM operations.
‐ Reported and forecast weather on the flight route.
‐ Review of maintenance logs and forms to determine the condition of equipment required for
flight in RVSM airspace. Ensure that maintenance action has been taken to correct defects to
required equipment.
‐ Check that each PFD altitude indication (QNH reference) does not differ from the airport
elevation by more than 75 ft.
‐ Check, on ground, that the difference between the two primary altitude indications on the PFD
is less than the tolerance specified in paragraph “Maximum Differences Between Altitude
Indications”. (Refer to PRO-SUP-34 FLIGHT INSTRUMENT TOLERANCES)
IN FLIGHT PROCEDURES
PRIOR TO RVSM AIRSPACE ENTRY
The required equipment for RVSM listed above must be operating normally.
Should any of this equipment fail prior entering the RVSM airspace, the crew must request a
new clearance so as to avoid flight in this airspace.
The two primary altitude indications (PFD indication from onside ADR or ADR 3) should be
checked to be in accordance with the instrument tolerances (Refer to PRO-SUP-34 FLIGHT
INSTRUMENT TOLERANCES).

If only two ADR are operative, the altimeter indications on PFD and standby altimeters should
be recorded. This information may be useful in case of subsequent PFD altitude discrepancy or
loss of both remaining ADR.
WITHIN RVSM AIRSPACE
Autopilot should be engaged within RVSM airspace for ‐ cruise and flight level changes.
‐ During cleared transitions between flight levels, the aircraft should not overshoot or
undershoot the cleared flight levels by more than 150 ft.
‐ At intervals of approximately one hour, check that PFD altimeter indications agree in
accordance with the instrument tolerances (Refer to PRO-SUP-34 FLIGHT INSTRUMENT
TOLERANCES). The usual scan of flight deck instruments should be sufficient.
