MODE TYPE GUIDANCE REMARK<br />

HDG-TRK SELECTED Mode used to guide the aircraft on a<br />

heading or a track selected by the flight<br />

crew. The target value is displayed in the<br />

FCU window.<br />

LOC*<br />

LOC<br />

APP NAV<br />

MANAGED Mode used to guide the aircraft on the<br />

lateral approach path (LOC or F-PLN<br />

approach path).<br />

LAND MANAGED Common mode engaged below 400 ft<br />

RA during an automatic ILS approach.<br />

ROLL OUT MANAGED Mode used to guide the aircraft on the<br />

runway following an automatic landing.<br />

LOC B/C*<br />

LOC B/C<br />

Applicable to: ALL<br />

MANAGED Mode used to guide the aircraft on the<br />

back beam of a localizer.<br />

VERTICAL MODES<br />

MODE TYPE GUIDANCE REMARK<br />

SRS MANAGED Mode used at takeoff, or go-around<br />

to maintain SRS speed (V2, V2+10,<br />

VAPP...).<br />

CLB MANAGED Mode used to climb towards FCU<br />

selected altitude along VERT F-PLN<br />

taking into account ALT CSTR.<br />

Available, only if NAV mode engaged.<br />

The A/THR is in THRUST mode (CLB).<br />

DES MANAGED Mode used to descend towards FCU<br />

selected altitude along the computed<br />

descent path, taking into account ALT<br />

CSTR. Available, only if NAV mode<br />

engaged.<br />

The A/THR may be in THRUST, or SPD<br />

mode.<br />

Note: HDG/TRK is called "basic<br />

mode" because it is a<br />

back up mode for certain<br />

situations :<br />

‐ F-PLN discontinuity entry<br />

‐ AP engagement with no<br />

FD<br />

‐ Loss of F-PLN<br />

‐ MCDU NAV BACK UP.<br />

Selected by pressing APPR pb on the<br />

FCU; the mode that engages depends<br />

upon the selected approach in the<br />

F-PLN.<br />

Engaged only if LOC mode and G/S<br />

mode are already engaged.<br />

FD roll out symbol is displayed on PFD<br />

at touch down.<br />

Selected by LAT REV at destination.<br />

Activated by pressing the LOC pb on the<br />

FCU.<br />

Triggered by the thrust levers at FLX or<br />

TOGA position.<br />

Automatically disengages at ACC<br />

ALT, or when another VERT mode is<br />

engaged.<br />

The speed target may either be selected<br />

or managed. If managed, SPD CSTR,<br />

SPD LIM, and HOLD SPD are taken into<br />

account.<br />

ALT mode is always armed; displayed in<br />

magenta, if the next level off is predicted<br />

at an ALT CSTR; and in blue, if the next<br />

level off is predicted at the FCU selected<br />

altitude.<br />
