During a normal entry into a turn, the pilot must make an intentional initial change to the pitch
attitude in order to maintain level flight. Once he has done this, he can release the stick. The
system then maintains a level turn.
In climb, cruise, descent, and approach all these basic rules remain in effect.
LANDING MODE
The system’s landing mode gives the aircraft a stabilized flight path and makes a conventional
flare and touchdown. It carries out the initial approach as this manual described earlier. At 50 ft,
the system memorizes the attitude, usually 3 ° or 4 ° nose up. From 30 ft down, this value washes
out over eight seconds to –2 °. The result is that the pilot has to exert a progressive pull to
increase pitch gently in the flare. He should pull the thrust levers back at or above 20 ft, and the
landing should occur without a long flare. Touchdown quality is better and more repeatable at fairly
flat attitudes. An audible “RETARD” callout reminds the pilot if he has not pulled back the thrust
levers when the aircraft has reached 20 ft.
Crosswind landings are conventional. The preferred technique is to use the rudder to align the
aircraft with the runway heading, during the flare, while using lateral control to maintain the aircraft
on the runway centerline (Refer to STLO-SOP-22-A LANDING - FLARE). The lateral control mode

does not change until the wheels are on the ground, so there is no discontinuity in the control laws.
The aircraft tends to roll gently in the conventional sense as drift decreases, and the pilot may
have to use some normal cross control to maintain roll attitude.
Even during an approach in considerable turbulence, the control system resists the disturbances
quite well without pilot inputs. In fact, the pilot should try to limit his control inputs to those
necessary to correct the flight path trajectory and leave the task of countering air disturbances to
the flight control system.
Derotation is conventional. The pilot releases the back pressure he was holding for the flare and
the nose wheel comes down nicely.
Pitch trim then resets to zero.

ENGINE FAILURE AT TAKEOFF
Applicable to: ALL
On the ground the aircraft is conventional. The pilot uses rudder to maintain direction. He should
rotate to about 12.5 ° of pitch and adjust as required. The sideslip indication (1) changes to the
engine-out mode (blue). When it is centered, the aircraft is close to the zero aileron position (best
drag condition). It is therefore important to zero the slip indication accurately.
Trim the rudder conventionally.
When time permits, the pilot should check the ECAM’s FLT CTL page, and refine the rudder trim
to give neutral lateral control, and also trim the rudder toward the spoilers that are up or toward the
aileron that is farthest up to bring the lateral controls back to neutral.
ENGINE-OUT LANDING
Applicable to: ALL
The engine-out landing is basically a conventional landing. The pilot should trim to maintain the slip
indication centered. It is yellow, as long as N1 is less than 80 %. Between 100 and 50 ft, the pilot can
reset rudder trim to make the landing run easier, and to recover full rudder travel in both directions.
BOUNCE AT LANDING
Applicable to: ALL
In case of a light bounce, maintain the current pitch attitude and complete the landing, while
maintaining the thrust at idle. In case of a high bounce, initiate a go-around, initially maintaining the
pitch attitude. Retract the flaps one step, and then the landing gear, once the aircraft is properly

established on the go-around segment. In all cases, do not attempt to soften the (potential) second
touchdown by increasing the pitch attitude.
