RWY
LATERAL MODE
Mode used at takeoff to guide the aircraft along the runway centerline, using LOC.
Triggered by the thrust levers at FLX or TOGA position.
RWY TRK
LATERAL MODE
Mode used to guide the aircraft along the track the aircraft was following at mode engagement.
Triggered by the thrust levers at FLX or TOGA position.
NAV
LATERAL MODE
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 LATERAL MODE
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 backup mode for certain situations:
- F-PLN discontinuity entry
- AP engagement with no FD
- Loss of F-PLN.
LOC*
LOC
APP NAV
MANAGED LATERAL MODE
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.
Note: For LOC only approach, do not select the FCU’s APPR pb, but rather the LOC pb.
LAND
MANAGED LATERAL MODE
Common mode engaged below 400 ft RA during an automatic ILS approach.
Engaged only if LOC mode and G/S mode are already engaged.
GA TRK
MANAGED LATERAL MODE
Mode used to guide the aircraft along the track the aircraft was following at mode engagement.
Triggered by the thrust levers at TOGA with Slats/Flaps in at least CONF 1.
ROLL OUT
MANAGED LATERAL MODE
Mode used to guide the aircraft on the runway, following an automatic landing.
FD rollout symbol is displayed on the PFD at touchdown.
SRS
MANAGED VERTICAL MODE
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. Disengages automatically at ACC ALT or when another
VERT mode is engaged.
CLB
MANAGED VERTICAL MODE
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).
The speed target may be either 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.
DES
MANAGED VERTICAL MODE
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 be either 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.
OP CLB
OP DES
SELECTED VERTICAL MODE
Mode used to climb/descent 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 be either selected or managed. ALT mode is systematically armed and blue. Altitude target is blue on PFD.
EXPEDITE
SELECTED VERTICAL MODE
Mode used to increase the vertical speed by selecting green dot in climb or 0.80/340 kt in descent.
Used to expedite a climb or descent towards a specific level.
ALT CST*
ALT CST
MANAGED VERTICAL MODE
Mode automatically engaged when reaching an ALT CSTR before the FCU selected altitude.
CLB/DES mode are systematically armed (blue).
