Fixed TO-GA and FLX mode are shown in white and are boxed in white frame. MAN is
added above mode name. For FLEX mode, assumed temperature is shown.
Other, active autothrust modes, are shown in green. “THR” is added before xed thrust
modes. When a mode automatically changes, the new mode is surrounded in white box
for several seconds.
A/THR status
When autothrust is armed, A/THR is shown in status column in Blue.
When autothrust is active, A/THR is shown in status column in White.
No indication is present with A/THR off.
Thrust reduction prompt
After takeoff, when passing Thrust reduction altitude which defaults to 1500 ft AGL, the
system reminds you to move thrust levers back to CL detent, so that A/THR can become
active. White “LVR CLB” ashes on thrust mode FMA until levers are placed in CL.

Alpha Floor
To aid in recovering from low speed / high angle of attack conditions, Alpha Floor autothrust mode is provided. Alpha Floor
automatically activates below a predetermined airspeed, if above 100 feet radio altitude, and commands TOGA thrust. Alpha Floor
engages regardless of A/THR status, and is available even with autothrust off and thrust levers at IDLE.
When Alpha Floor activates, green A.FLOOR in amber box ashes on thrust FMA.
During high alpha conditions, engaged Alpha Floor mode is the only possible autothrust
mode. When engagement conditions no longer exist, the thrust remains locked at TOGA
power. This condition is called TOGA LOCK. To unlock the thrust, the A/THR system must
be rst deactivated.

Speed guidance
Selected speeds
Pilot uses selected speed guidance to manually set the desired speed. The target speed is displayed in
FCU SPD/MACH window, and is selected with SPD selector knob. Regardless of selected speed, the
autothrust will not exceed maximum or minimum aircraft speed limits for current conguration.
Selected speed guidance is activated by Pulling the SPD selector knob. This action opens the
SPD/MACH window to current airspeed or mach. Selector knob can be rotated to select desired
speed target.
SPD/MACH button toggles between Airspeed and Mach modes. In Mach mode, the FCU window
shows mach number. The current mode automatically switches from Speed to Mach at predetermined
altitude, and vice versa.
Managed speeds
Managed speed guidance automatically controls computed speeds according to ight plan performance
speeds, speed constraints and limits, or default ight phase speeds if ight plan is not followed.
Managed speed guidance is activated by Pushing the SPD selector knob. The FCU speed window
becomes dashed, and a white dot appears next to the window indicating that this function is in
managed guidance mode.

knob
The selector knobs are controlled with mouse.
To Push a knob, click its center with LEFT mouse button.
To Pull a knob, click its center with RIGHT mouse button.
To rotate, click to the left or right of the knob. Right-clicking will turn the knob with increased rate.
You can also turn knobs by moving the mouse to one if its sides and scrolling the mouse wheel.

Lateral guidance
Selected lateral modes
Two selected lateral modes are available, HDG and TRACK. These modes maintain selected heading
or ground track.
Selected lateral guidance is activated by pulling the HDG/TRK selector knob. HDG/TRK window opens
with current heading or track.
With selected lateral guidance active, turning the HDG selector knob will select a new heading or
track. The aircraft will turn towards the new target in the direction of knob turn. The turn will continue
in this direction even if a turn of more than 180° will be required. This is different to Boeing aircraft
which will reverse the turn when the heading window is scrolled through the heading reciprocal to the
existing one.
The guidance is toggled between HDG and TRACK by pushing the HDG-VS / TRK-FPA button on FCU. When such toggle occurs,
the value in HDG window switches from heading to track and back.
Managed NAV mode
NAV mode provides lateral guidance along the ight plan entered into FMS. It is manually engaged by
pushing the HDG/TRK selector knob. NAV mode is also automatically armed on the ground after a ight
plan is entered.
