Performance Specification (MNPS) airspace by referring to specific manuals, such as, for
example, the North Atlantic (NAT) MNPS Manual.
If unable to notify ATC and obtain ATC clearance prior to deviating from the assigned cleared flight
level, the crew should follow the established contingency procedure and obtain ATC clearance as
soon as possible.

GENERAL
The aircraft navigation system, required by regulation to fly within a Required Navigation
Performance (RNP) airspace, shall comply with RNAV functionality criteria and with navigation
position accuracy and integrity criteria.
When referring to RNP-X, the value of X is the navigation accuracy expressed in NM, which has to
be met with a probability of 95 %.
An RNP value can be associated with an airspace, a route, a SID, a STAR, a RNAV approach, or
an RNAV missed approach procedure.
Depending on the RNP value, and on the airspace environment (ground radio navaid), different
navigation equipment may be necessary.
An operational approval from the airline's national authorities may be necessary.
Applicable to: ALL
NAVIGATION SYSTEM CAPABILITY (FOR REFERENCE ONLY)
European BRNAV (RNP-5) and P-RNAV (RNP-1) capability meets the certification requirements
of JAA TGL 2 and TGL 10. Terminal and en-route RNAV operations comply with the certification
requirements of the FAA Advisory Circular 90-100.
RNP-10 capability in oceanic or remote areas complies with paragraph 12.b (1) of FAA Notice
8400.12a., or with paragraph 12.a. or 12.b (5), if GPS is installed and is operative.
Navigation system with the GPS PRIMARY function (if GPS installed) meets the certification
requirements of FAA AC 20-130A and TSO C 129A in class C1 (for navigation system with
multiple sensor inputs including GPS).
Applicable to:
In order to match a given RNP value, the FMS-estimated position accuracy (also called Estimated
Position Error) must be better than the RNP value. Obviously, this is dependent on the FMS
navigation-updating mode (GPS/DME/DME, VORDME, or IRS).
On the MCDU PROG page, the required and the estimated position accuracy are displayed, and
determine the HIGH/LOW accuracy indication (Refer to STLO-22_20_R-10 GENERAL).
The required accuracy can be a default value, which is either a function of the flight phase, or a value
manually-entered by the crew
When flying in an RNP environment, the crew can insert the appropriate RNP value in the
REQUIRED ACCUR field of the PROG page.
When HIGH is displayed
The RNP requirement is estimated to be fulfilled.

When LOW is displayed
The RNP requirement is estimated not to be fulfilled. In this case :
• The crew crosschecks navigation with raw data, if available,
• If the crosscheck is negative, or if raw data is unavailable, the crew informs the ATC.
When leaving the RNP environment, the crew will clear the manually-entered required accuracy.
WITHOUT GPS PRIMARY FUNCTION
RNP accuracy criteria are met, provided radio navaid coverage supports it for :
‐ RNP-1 en route and in the terminal area, provided a required accuracy of 1 nm See (1) is
checked, or manually entered in the MCDU.
‐ RNP-0.3 in approach, provided a required accuracy of 0.3 nm See (1) is checked, or manually
entered in the MCDU.
Note: (1) It is possible to enter the radial equivalent to the specified Crosstrack (XTK) accuracy,
that is the RNP multiplied by 1.2, the EPE being an estimated radial position error.
WITH THE GPS PRIMARY FUNCTION
RNP requirements are met, provided GPS PRIMARY is available, for :
‐ RNP-1 en route
‐ RNP-0.5 in the terminal areas, provided the AP or FD in NAV mode is used.
‐ RNP-0.3 in approach, provided the AP or FD in NAV mode is used.
