configuration 4 (Full). After the flaps were extended to configuration 4, the aircraft descended on
the glide slope in the landing configuration with the localizer and glide-slope beams captured.
The speed was controlled by the autothrust. The target speed of 137 kt was equal to the actual
speed.
Therefore, the aircraft was stabilized on the glide-slope, in the landing configuration and was
completely ready for landing.
At 22:11:25 the crew proceeded to the landing check list (Attachment 2, Fig. 4).
The segment of the automatic flight from controller’s instruction to stop descent to the
moment when the autopilot was disengaged.
At 22:11:40 the controller instructed: “RNV 967, stop descent, cloud 100 meters, turn right,
climb 600”. The crew confirmed: “Turn right, climb 600, 967”. At that moment the aircraft was

at a distance of 7 km from the end of RW 06, the flight altitude was 1,280 ft (390 m), and the
indicated airspeed was 139 kt (257 km/h). The thrust control levers were in the CL position
(Attachment 2, Fig.2). It should be noted that the controller did not give a direct instruction to the
crew to go around.
The standard go-around procedure described in the A320 FCOM provides for the following order
of actions:
-Carry out following three actions simultaneously:
- THRUST CONTROL LEVER TOGA (takeoff)
COMMAND GO AROUND – FLAPS
AIRCRAFT PITCHING CARRY OUT
• Set aircraft to climb to achieve positive vertical speed and set required yaw as in director
command panels
• activate audio indication on FMA: MAN TOGA, SRS, GA TRK
- MECHANIZATION HANDLE BACK ONE STAGE
activate sound for this
ACTIVATE SOUND POSITIVE VERTICAL SPEED
COMMAND RETRACT LANDING GEAR
LEVER TO RETRACT POSITION MOVE
ACTIVATE SOUND LANDING GEAR RETRACTED – FLAPS
N.B. If TOGA (takeoff) mode is not required - set CL mode
mode NAV or HDG DESELECT
Reselect NAV or HDG mode as required (minimum height 100 ft).
N.B. Go-around can be carried out with two autopilots switched on. When any other
mode is selected, the second autopilot is switched off.
• At throttling height when turning to go around (LVR CLB blinks on FMA)
THRUST CONTROL LEVER To CL position
• At acceleration altitude when turning to go around:
- Make sure the set speed is increased to the green dot (GREEN DOT);
• If not:
FCU ALT CHECK AND TIGHTEN
- retract flaps under standard procedure

TURNING TO GO AROUND FROM INTERMEDIATE APPROACH ALTITUDE
To interrupt an approach or to turn to second course from intermediate approach altitude, and if
TOGA is not required, follow this procedure:
- MOVE THRUST CONTROL LEVERS to TOGA stop and then throttle back as
necessary
This enables the turn to go around mode to be activated along with the associated
autopilot and director modes.
SELECT required modes for AUTOPILOT/DIRECTOR AND AUTOMATIC THRUST
on FCU
Further on, this section contains a warning about the possibility of reducing speed below VLS
when interrupting fulfilment of a landing approach on autopilot and automatic throttle, if modes
V/S or OP CLB are subsequently switched on.
The go-around procedure for RW 06 in Sochi airport provides for a coupled right-hand climbing
turn at heading 240º in the take-off configuration, with the roll angle at least 20 degrees and at a
speed not exceeding 200 kt, with climb to 600 m (2,060 ft) at the maximum possible vertical
speed.
After the controller’s instruction, at 22:11:48:5, the PTLO (PUSH TO LEVEL OFF) button was
pushed to bring the aircraft to level flight immediately. As a result, the autopilot pitch mode
changed to the VS MODE (the preset vertical speed was 0 m/s). The pitch angle increased to 6º.
Autopilot 2 disengaged automatically, since two autopilots can work simultaneously only during
approach. An audible signal advised the crew of the aircraft’s capability of performing ICAO
Category 2 and 3 approaches as downgraded (ILS CAPABILITY DOWNGRADE). The autopilot
lateral-directional mode automatically changed to HDG, with the preset heading equal to the
current aircraft heading of 62º.
At the same time as the VS MODE was activated, the pedals were moved to the -1.4º position
(the minimum pedal force required to move the pedals from the neutral position is ~10 kg). It
should be noted that the A320 does not require the use of the pedals in a normal flight. During a
turn the aircraft co-ordinates its movements automatically.
At 22:11:52 a heading of 172º was set with the use of the selector on FCU. As a result, the
aircraft entered a turn to the right with a roll angle up to 25º, maintaining an altitude of 1,114 ft
