Special Operations - PRO-SPO-50 Reduced Vertical Separation Minimum (RVSM)

Question 1

016- What’s the Definition of RVSM?

PRO-SPO-50 P1

Answer 1

Reduced Vertical Separation Minimum (RVSM)

• Any Airspace or Route between FL 290 and FL 410

where Aircraft are Vertically Separated by 1 000 Ft

Instead of 2 000 Ft.

Question 2

017- What’s the Operational Approval for RVSM?

PRO-SPO-50 P1

Answer 2

Operational approval:

• Is Granted by the Operator’s National Authorities, after

Assessment of the Airline’s Capability to Meet RVSM

Requirements.

Question 3

018- Where to Find the Required Equipment / Functions For RVSM?

PRO-SPO-50 P1

Answer 3

SPECIAL OPERATIONS

Reduced Vertical Separation Minimum (RVSM)

PRO-SPO-50 P1.

Question 4

019- What are the Altitude Margins between Onboard Instruments for an RVSM Flight (at Flight Preparation Stage)?

PRO-SPO-50 P2

Answer 4

• PFD Alt. (QNH Ref.) ≤ 75 Ft from the ARPT Elevation
• Diff. between the 2 Primary Alt Indications is Less than

what’s specified in:

* PRO-SUP-34

(Flight Instrument Tolerances)

(General)

(Max Differences Between Altitude Indications).

Question 5

020- What are the ADR Restrictions PRIOR Entering RVSM Airspace?

PRO-SPO-50 P3

Answer 5

If Only 2 ADRs are Operative:

• The Altimeter Indications on the PFD and Stby Altimeters

should be Recorded.

* This Information may be Useful in case of Subsequent

PFD Altitude Discrepancies or the Loss of Both

Remaining ADRs.

Question 6

021- What are the Tolerance Within RVSM Airspace?

PRO-SPO-50 P3

Answer 6

• Autopilot ON within RVSM for CRZ and FL Changes
• Never Over/Undershoot the FL by more than 150 Ft
• Every 1H, check that PFD ALTI Ind. is within the

Instrument Tolerance (Normal Scan, PRO-SUP-34)

• Use the Transponder and A/P Associated with the ADR

which is Within Tolerance.

Question 7

022- What are the Elements Needed to be Reported to ATC in case of Failure in RVSM Airspace?

PRO-SPO-50 P5

Answer 7

• Failure of Both A/P
• Loss of Altimeter System Redundancy (only one PFD

Indication Remaining)

• Altimeter Discrepancy (>200 Ft)
• Failure of any Equipment Affecting the Ability to

Maintain the Cleared FL

• Encountering Greater than Moderate Turbulence
• Loss of RVSM Capability.

Question 8

023- Within RVSM Airspace If the Crew is Unable to Notify / Obtain ATC Clearance Prior to a deviation from the Cleared FL, What should be done?

PRO-SPO-50 P5

Answer 8

The crew should Follow the Established Contingency Procedure and obtain ATC Clearance as Soon as Possible.
