to flare on the pitch axis. If the autothrust is active, thrust is automatically reduced to IDLE during
flare (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 that lines up the aircraft’s axis with the ILS course at
approximately 45 ft. Align sub-mode is not displayed to the flight crew.
Note: Align sub-mode is often known as "decrab" function.
ROLL OUT MODE
At touchdown, 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 FMGES or selected by the flight crew:
When managed, the FMGES computes the speed target and the ‐ flight crew may modify it via the
MCDU. At 700 ft RA, the autothrust memorizes the current speed target value, to ensure stabilized
speed guidance, even if Flight Management fails. Below 700 ft, any new VAPP or WIND entry in
the MCDU does not have an effect on the speed target.
‐ When selected, the autothrust always targets the speed selected on the FCU.
TYPICAL ILS APPROACH
Applicable to: ALL
AUTOLAND WARNING LIGHT
Applicable to: ALL
When the following situations occur below 200 ft RA with the aircraft in LAND mode, the flashing
AUTOLAND red warning and a triple-click aural warning are triggered:
‐ 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. In addition, the FD bars flash
on the PFD. LAND mode remains engaged.
‐ The difference between both radio altimeter indications is above 15 ft.

LANDING CAPABILITIES
Applicable to: ALL
Each FMGEC computes its own automatic landing capability in accordance with the availability of
computers, sensors, or functions.
The FMA displays the "CAT 1", "CAT 2", "CAT 3 SINGLE" or "CAT 3 DUAL" messages as soon as
the flight crew pushes the APPR pb to arm ILS approach modes.
Refer to PRO-NOR-SRP-01-70 INITIAL APPROACH.

Non Precision Approach
GENERAL
Applicable to: ALL
This mode guides the aircraft laterally and vertically down to the Minimum Descent Altitude (MDA) or
Minimum Descent Height (MDH) along the final descent profile computed by the FMGES.
This mode is used to fly a non-ILS approach (VOR, VOR/DME, NDB (if ADF ), RNAV...) as
inserted into the flight plan.

A non-precision approach includes the following managed modes:
‐ APP NAV mode for lateral guidance
‐ FINAL mode for vertical guidance.
SELECTION
Applicable to: ALL
The non-precision approach guidance modes are available if a non-precision approach (VOR,
VOR/DME, NDB (if ADF ), RNAV) has been inserted in the active flight plan.
ARMING CONDITIONS
Applicable to: ALL
The flight crew arms APP NAV and FINAL modes by pressing the APPR pb on the FCU, provided all
of the following conditions are met:
‐ The aircraft is above 400 ft AGL
‐ The active flight plan is valid (lateral and vertical profile)
