MODE TYPE GUIDANCE REMARK
OP CLB
OP DES
SELECTED Mode used to climb/descend directly to
the FCU selected altitude. These modes
disregard all ALT CSTR. The A/THR is
in THRUST mode (CLB/IDLE)
The speed target may either be selected
or managed. ALT mode is systematically
armed and blue. Altitude target is blue on
the PFD.
ALT CST*
ALT CST
MANAGED Mode automatically engaged when
reaching an ALT CSTR before the FCU
selected altitude.
CLB/DES mode are systematically
armed (blue).

ALT CRZ
SELECTED Mode used to maintain a level flight at
the FCU selected altitude.
A/THR SOFT mode engages when FCU
selected altitude = CRZ FL.
A/THR SOFT mode is part of the
managed guidance.
V/S-FPA SELECTED Mode used to guide the aircraft along a
vertical speed, or a selected flight path
angle.
Altitude target is blue on PFD. V/S-FPA
is a basic mode.
(Refer to DSC-22_30-10 Lateral Modes).
G/S*

FINAL
MANAGED Mode used to guide the aircraft along
the final approach path (G/S or non ILS)
Selected by pressing the FCU's APPR
pb. The mode engaged depends upon
the selected approach in the F-PLN.
Linked to APPR common mode (APPR
pb).
FLARE MANAGED Common mode which provides
alignment to the runway centerline on
the yaw axis, and flare on the pitch axis.
Engages below 50 ft RA, based on the
current vertical speed.

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
(at takeoff only), 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
level off is predicted at the FCU selected
altitude.
