MODE SELECTION
Applicable to: ALL
MANAGED MODES
At takeoff, the managed modes engage automatically when the ‐ flight crew sets the thrust levers
at the TO or FLX detent.
‐ During flight, the flight crew can arm or engage the managed modes (if the aircraft meets
engagement conditions) by pushing in the appropriate knobs on the Flight Control Unit (FCU).
‐ The flight crew pushes the DIR TO key on the MCDU to insert a DIR TO leg. It engages or
maintains the NAV mode.
‐ The flight crew pushes the APPR pb on the FCU to arm or engage the localizer and glide slope
or “APP NAV-FINAL”, depending on the approach type they insert in the flight plan.
‐ The LOC pb arms or engages the localizer mode only.
SELECTED MODES
The flight crew can engage the selected modes by pulling out the appropriate FCU selection
knobs.
LATERAL MODES
Applicable to: ALL
MODE TYPE GUIDANCE REMARK
RWY MANAGED Mode used at takeoff to guide the aircraft
along the runway center line using LOC.
RWY TRK MANAGED Mode used to guide the aircraft along
the track the aircraft was following at the
mode engagement.
Triggered by the thrust levers at FLX or
TOGA position.
GA TRK MANAGED Mode used to guide the aircraft along
the track the aircraft was following at the
mode engagement.
Triggered by the thrust levers at TOGA
with Slats/Flaps in at least CONF 1.
NAV MANAGED Mode used to guide the aircraft along the
lateral F-PLN. Available above 30 ft after
takeoff.
Automatically armed at takeoff unless
HDG/TRK is preset.
In that case RWY TRK engages after
takeoff.

HDG-TRK SELECTED Mode used to guide the aircraft on a
heading or a track selected by the flight
crew. The target value is displayed in the
FCU window.
Note: HDG/TRK is called "basic
mode" because it is a back up
mode for certain situations :
‐ F-PLN discontinuity entry
‐ AP engagement with no
FD
‐ Loss of F-PLN
‐ MCDU NAV BACK UP.
LOC*
LOC
APP NAV
MANAGED Mode used to guide the aircraft on the
lateral approach path (LOC or F-PLN
approach path).
Selected by pressing APPR pb on the
FCU; the mode that engages depends
upon the selected approach in the
F-PLN.
LAND MANAGED Common mode engaged below 400 ft
RA during an automatic ILS approach.
Engaged only if LOC mode and G/S
mode are already engaged.
ROLL OUT MANAGED Mode used to guide the aircraft on the
runway following an automatic landing.
FD roll out symbol is displayed on PFD at
touch down.

Applicable to:
MODE TYPE GUIDANCE REMARK
SRS MANAGED Mode used at takeoff, or go-around
to maintain SRS speed (V2, V2+10,
VAPP...).
Triggered by the thrust levers at FLX or
TOGA position.
Automatically disengages at ACC
ALT, or when another VERT mode is
engaged.
CLB MANAGED Mode used to climb towards FCU
selected altitude along VERT F-PLN
taking into account ALT CSTR.
Available, only if NAV mode engaged.
The A/THR is in THRUST mode (CLB).
DES MANAGED Mode used to descend towards FCU
selected altitude along the computed
descent path, taking into account ALT
CSTR. Available, only if NAV mode
engaged.
The A/THR may be in THRUST, or SPD
mode.
The speed target may either be selected
or managed. If managed, SPD CSTR,
SPD LIM, and HOLD SPD are taken into
account.
ALT mode is always armed; displayed in
magenta, if the next level off is predicted
at an ALT CSTR; and in blue, if the next
