FLS final approaches)
‐ Missed approach procedures.
The navigation accuracy depends on:

• Elapsed time since last computation of radio navaid position.
RNP AR capability has been demonstrated with AP ON for the following modes:
‐ Departure in NAV mode

‐ Final approach in FINAL APP mode
‐ Missed approach in NAV mode.
AFTER TAKEOFF
NAV mode may be used after takeoff provided that:

‐ The flight crew checked the FMGS takeoff updating
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.
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.
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.
