‐ The “RWY/ILS MISMATCH” message is displayed on the scratchpad
‐ The flight crew should select HDG mode to perform the LOC capture.
Note: There is no glideslope capture assistance. The flight crew shall ensure that the aircraft
flight path intercepts the G/S beam.

Applicable to:
LAND MODE
ENGAGEMENT CONDITIONS
LAND mode automatically engages when the LOC and G/S modes are engaged, and the
aircraft is below 400 ft RA. The FMA displays “LAND”, indicating that LOC and G/S are
locked. No action on the FCU will disengage LAND mode. FLARE and ROLL OUT modes will
successively engage.
DISENGAGEMENT CONDITIONS
LAND mode disengages:
‐ Upon engagement of the go-around mode
‐ If the flight crew presses the APPR pb, when the aircraft has been on ground for at least 10 s
with the autopilot disconnected.
Note: When LAND is not displayed on the FMA, at/or slightly below 400 ft, the landing
capability degrades to CAT 1 and the triple click is generated. No autoland is
authorized with CAT 1 displayed on the FMA.

FLARE MODE
Once the aircraft reaches approximately 40 ft RA (the precise value is a function of V/S):
‐ The FLARE mode engages
‐ The FMA displays “FLARE” in green.
At 30 ft RA, the AP/FD aligns the yaw axis with the runway centerline and the aircraft flares
on the pitch axis. If the autothrust is active, thrust is automatically reduced to IDLE (Refer to
DSC-22_30-90-C A/THR Modes - RETARD Mode).
When both AP/FDs are disengaged, FLARE mode disengages.
After main landing gear touchdown, the autopilot (if engaged) sends a nose down order.
ALIGN SUB-MODE
ALIGN is a sub-mode of LAND mode that lines up the aircraft’s axis with the ILS course. It is not
displayed to the flight crew.
Applicable to: ALL
ROLL OUT MODE
At touchdown, the ROLL OUT mode engages and guides the aircraft along the runway centerline.
The FMA displays “ROLL OUT” in green, and the PFD displays the yaw bar and no FD bars.
SPEED CONTROL
Applicable to: ALL
The autothrust, when active, controls speed. The approach speed target (VAPP) is either managed
by the FMGS or selected by the flight crew:
When managed, the speed ‐ target is computed by the FMGS and may be modified by the flight
crew through the MCDU. At 700 ft RA, the current speed target value is memorized by the
autothrust, to ensure stabilized speed guidance, even if Flight Management fails. Below 700 ft, any
new VAPP or WIND entry in the MCDU has no effect on the speed target.
‐ When selected, the autothrust always targets the speed selected on the FCU.

AUTOLAND WARNING LIGHT
Applicable to: ALL
The following situations, when occurring below 200 ft RA with the aircraft in LAND mode, trigger the
flashing Autoland red warning and a triple click aural warning:
‐ Both APs OFF below 200 ft RA.
‐ Excessive deviation in LOC (1/4 dot above 15 ft RA) or GLIDE (1 dot above 100 ft RA). In addition,
LOC and GLIDE scales flash on the PFD.
‐ Loss of LOC signal above 15 ft, or loss of GLIDE signal above 100 ft. The FD bars flash on the
