Navigation Performance
The navigation accuracy depends on:
‐ IRS drift, or
‐ One of the following:
• Radio navaid availability, or
• Elapsed time since last computation of radio navaid position.
Navigation Performance
The navigation accuracy depends on:
‐ IRS drift, or
‐ One of the following:
• Radio navaid availability, or
• Elapsed time since last computation of radio navaid position.
RNP Accuracy with GPS Primary
En Route : __ nm
In terminal area : __ nm
In approach: ___ nm
RNP Accuracy with GPS Primary
En Route : 1 nm
In terminal area : 0.5 nm
In approach : 0.3 nm
Degraded situation
If GPS PRIMARY LOST is displayed on the ND and MCDU, the navigation accuracy remains
sufficient for RNP operations provided that, the RNP value is checked or entered on the MCDU
and HIGH ACCURACY is displayed.

Use of NAV mode after takeoff
NAV mode may be used after takeoff provided that:
‐ GPS PRIMARY is available, or
‐ The flight crew checked the FMGS takeoff updating.
and HIGH ACCURACY is displayed.
Use of NAV mode after takeoff
NAV mode may be used after takeoff provided that:
‐ GPS PRIMARY is available, or
‐ The flight crew checked the FMGS takeoff updating.
Use of NAV mode in terminal area
NAV mode may be used in terminal area provided that:
‐ GPS PRIMARY is available, or
‐ the appropriate RNP is checked or entered on the MCDU, and HIGH accuracy is displayed, or
‐ FMS navigation is crosschecked with navaid raw data.
Use of NAV mode in terminal area
NAV mode may be used in terminal area provided that:
‐ GPS PRIMARY is available, or
‐ the appropriate RNP is checked or entered on the MCDU, and HIGH accuracy is displayed, or
‐ FMS navigation is crosschecked with navaid raw data.
Approach based on Radio Navaids
A navaids approach may be performed in NAV, APP NAV or FINAL APP, with AP or FD engaged,
provided that:
‐ If GPS PRIMARY is available, the reference navaid may be unserviceable, or the airborne
radio equipment may be inoperative, or not installed, provided that an operational approval is
obtained
‐ If GPS PRIMARY is not available, the reference navaid and the corresponding airborne radio
equipment must be serviceable, tuned and monitored during the approach.
Approach based on Radio Navaids
A navaids approach may be performed in NAV, APP NAV or FINAL APP, with AP or FD engaged,
provided that:
‐ If GPS PRIMARY is available, the reference navaid may be unserviceable, or the airborne
radio equipment may be inoperative, or not installed, provided that an operational approval is
obtained
‐ If GPS PRIMARY is not available, the reference navaid and the corresponding airborne radio
equipment must be serviceable, tuned and monitored during the approach.
RNAV Approach
An RNAV(RNP) approach may be performed, with GPS PRIMARY not available, only if the radio
navaid coverage supports the RNP value and HIGH accuracy is displayed on the MCDU with the
specified RNP, and an operational approval is obtained.
An RNAV(GNSS) approach may be performed provided that GPS PRIMARY is available.
RNAV Approach
An RNAV(RNP) approach may be performed, with GPS PRIMARY not available, only if the radio
navaid coverage supports the RNP value and HIGH accuracy is displayed on the MCDU with the
specified RNP, and an operational approval is obtained.
An RNAV(GNSS) approach may be performed provided that GPS PRIMARY is available.
Non-precision approaches with engine - out
If one engine is inoperative, it is not permitted to use the autopilot to perform NPAs in the following
modes: FINAL APP, NAV V/S, NAV/FPA.
Only FD use is permitted.
