‐ A non-precision approach has been selected in the active flight plan
‐ GA mode is not engaged.
The FMA displays "FINAL" and "APP NAV" in blue.
If NAV mode was already engaged, APP NAV engages immediately.
DISARMING CONDITIONS
Applicable to: ALL
FINAL and NAV modes are disarmed if the flight crew:
‐ Presses the APPR pb, or
Presses ‐ the LOC pb arming LOC mode, or
‐ Engages GO AROUND mode.
ENGAGEMENT CONDITIONS
Applicable to: ALL
APP NAV and NAV modes engage under the same conditions:
If NAV mode was engaged, APP NAV engages immediately. If HDG/TRK is engaged, APP NAV
engages when the intercept conditions are met (the aircraft’s heading or track intercepts the flight
plan active leg).

FINAL mode engages, if:
‐ The APPR phase is active, and the deceleration point has been sequenced, and
‐ APP NAV mode is engaged, and
‐ The crosstrack error is less than 1.5 nm, and
‐ FINAL mode is armed, and:
• The aircraft intercepts a descending leg of the vertical flight path, or
• In V/S (FPA) or OPEN DES mode, the aircraft intercepts a level-off segment of the vertical flight
profile, with a selected altitude different from this level-off segment.
If the aircraft trajectory does not intercept the approach profile computed by the FMGES, the FINAL
mode will not engage:

DISENGAGEMENT CONDITIONS
Applicable to: ALL
The FINAL and APP NAV modes disengage:
‐ If the flight crew presses the APPR pb (HDG-V/S or TRK-FPA modes engage)
‐ If the flight crew presses the LOC pb (LOC mode arms if an ILS is selected, if not, HDG-V/S or
TRK-FPA modes engage)
‐ If the flight crew pulls out the HDG/TRK knob, the FMGES reverts to HDG-V/S or TRK-FPA basic
modes
‐ Automatically at MDA (or MDH)-50 ft, or 400 ft AGL, if the flight crew does not enter any
MDA/MDH
‐ When the GO AROUND mode engages.
Note: If the flight crew engages the V/S or FPA mode, only FINAL mode disengages and APP
NAV mode remains engaged.

GUIDANCE
Applicable to: ALL
FINAL mode guides the aircraft on the vertical profile down to the MDA (or MDH if QFE pin program
�� ).
FINAL mode:
Displays a vertical deviation scale (± 200 ft) on the ‐ PFD and a VDEV symbol that indicates
deviation from descent path
‐ Anticipates leaving the altitude that the FCU selects, when the aircraft reaches the Continue
Descent symbol (blue arrow on the ND)
‐ Provides precise vertical guidance on the descent and final path with an internal vertical speed
limitation to prevent excessive V/S.
If the autopilot is engaged when the APP NAV/FINAL modes are in use, it automatically disengages
at MDA (or MDH)-50 ft.
FD modes revert to HDG-V/S or TRK-FPA basic modes.
WARNING
Applicable to: ALL
If during a non-precision approach, the GPS PRIMARY function is lost, a triple click aural warning is
triggered.

GENERAL
Applicable to: ALL
Go-around mode combines the Speed Reference System (SRS) vertical mode with the GA TRK
lateral mode.
ENGAGEMENT CONDITIONS
Applicable to: ALL
Setting at least one thrust lever to the TOGA detent engages both SRS/GA TRK modes, if:
‐ The flaps lever is at least in position 1, and
‐ The aircraft is in flight, or
‐ The aircraft has been on ground for less than 30 s (AP disengages and can be re-engaged 5 s
after liftoff).
FD bars are automatically restored in SRS/GA TRK modes. If FPD-FPV was selected for approach, it
reverts to FD bars.
The FMA displays “SRS” and “GA TRK” in green.
DISENGAGEMENT CONDITIONS
Applicable to:
The SRS mode disengages:
‐ Automatically, at the go-around acceleration altitude (GA ACC ALT), or if ALT* or ALT CST* mode
engages (above 400 ft RA)
‐ If the flight crew engages another vertical mode
‐ If the flight crew selects a speed while in SRS mode: SRS reverts to OP CLB mode.
