Question 1

711 Fcom

Answer 1

711 Fcom

Question 2

RWY

Answer 2

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.

Question 3

RWY TRK

Answer 3

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.

Question 4

NAV

Answer 4

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.

Question 5

HDG-TRK

Answer 5

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.

Question 6

LOC*
LOC
APP NAV

Answer 6

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.

Question 7

LAND

Answer 7

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.

Question 8

GA TRK

Answer 8

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.

Question 9

ROLL OUT

Answer 9

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.

Question 10

SRS

Answer 10

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.

Question 11

CLB

Answer 11

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.

Question 12

DES

Answer 12

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.

Question 13

OP CLB

OP DES

Answer 13

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.

Question 14

EXPEDITE

Answer 14

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.

Question 15

ALT CST*

ALT CST

Answer 15

MANAGED VERTICAL MODE

Mode automatically engaged when reaching an ALT CSTR before the FCU selected altitude.

CLB/DES mode are systematically armed (blue).

Question 16

ALT*
ALT
ALT CRZ

Answer 16

SELECTED VERTICAL MODE

Mode used to maintain a level flight at the FCU selected altitude.

Soft ALT mode engages when FCU selected altitude = CRZ FL. Soft ALT is part of the managed guidance.

Question 17

V/S-FPA

Answer 17

SELECTED VERTICAL MODE

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.

Question 18

G/S*
G/S
FINAL

Answer 18

MANAGED VERTICAL MODE

Mode used to guide the aircraft along the final approach path (G/S or non ILS)

Selected by depressing the APPR pb on the FCU. The mode engaged depends upon the selected approach in the F-PLN. Linked to APPR common mode (APPR pb).

Question 19

FLARE

Answer 19

MANAGED VERTICAL MODE

Common mode which provides the alignment to the runway center line on the yaw axis and the flare on the pitch axis.

Engages below 50 ft RA as a function of the current vertical speed.
