PREFACE
Failure to recognize the need for and to execute a go-around, when required, is a
major cause of approach and landing accidents. Because a go-around is an
infrequent occurrence, it is important to be "go-around minded". The decision to
go-around should not be delayed, as an early go-around is safer than a last minute
one at lower altitude.
FCTM
CONSIDERATIONS ABOUT GO-AROUND
A go-around must be considered if:
• There is a loss or a doubt about situation awareness
• If there is a malfunction which jeopardizes the safe completion of the approach
e.g. Major navigation problem
• ATC changes the final approach clearance resulting in rushed action from the
crew or potentially unstable approach
• The approach is unstable in speed, altitude, and flight path in such a way that
stability will not be obtained by 1000 ft IMC or 500 ft VMC
• Any GPWS, TCAS or windshear alert occur
• Adequate visual cues are not obtained reaching the minima.
FCTM
• a navigation radio or flight instrument failure occurs which affects the ability to
safely complete the approach
• the navigation instruments show significant disagreement
• on an RNP based approach and an alert message indicates that ANP exceeds RNP
• on a radar approach and radio communication is lost.

(B) Approach Stabilization
(1) Straight-in approaches shall be stabilized at 1000ft AAL.
(2) Non-straight-in approaches shall be stabilized at 500ft AAL.
(3) Depending on the type of approach, PM/PNF will callout 1000ft or
500ft.
(4) PF will reply:
(a) “STABILIZED” and continue the approach, or
(b) “GO-AROUND” and initiate go-around.

(C) Stable Approach Criteria
An approach is said to be stabilized when all of the conditions below are met and
maintained until touchdown.
(1) All briefings and checklists have been completed.
(2) ILS approaches must be flown within one dot of the localizer and glide slope.
(3) Non-precision approaches maximum deviation from VOR is ½ dot or 2.5 degrees and
NDB is 5 degrees.
(4) Only small changes in heading/pitch are required to maintain the correct flight path.
(5) The aircraft indicated airspeed is between [VREF and VREF + 20] or as adjusted by
minimum ground speed methods and power setting appropriate for airplane
configuration.
(6) Power setting is no less than minimum approach power.
(7) The aircraft is in the correct landing configuration.
(8) Rate of descent is not greater than 1000 fpm.
Note: For straight-in approaches speed and/or power requirements as indicated above
could be delayed until 500ft AAL if all other criteria are already met.
OPERATIONS MANUAL
PART-B NON-TYPE
(H) A detailed go-around briefing should be included in the descent and approach briefing,
highlighting the key points of the go-around maneuver and missed approach procedures,
and the planned task sharing under normal or non - normal conditions.
(1) The go-around briefing should include the following key topics:
(a) Go-around callout (i.e., a loud and clear go-around, flaps call)
(b) PF and PM/PNF task sharing (e.g., flow of respective actions, including use of the
autopilot, speed restrictions, go-around altitude, deviation callouts)
(c) Intended use of automation (i.e., automatic or manual go-around, use of FMS lateral
navigation or use of selected modes for missed approach)
(d) Missed approach lateral navigation and vertical profile (e.g., speed limitations, airspace
restrictions, potential obstacles, terrain features)
(e) Intentions (i.e., second approach or diversion)
1. If a second approach is intended, discuss the type of approach if a different runway
or type of approach is planned.
2. Confirm the minimum diversion fuel.

Apply the following three actions simultaneously:
THRUST levers.....................................................................................TOGA
If TOGA thrust is not required, set the thrust levers to TOGA detent then retard the
thrust levers as required. This enables to engage the GO-AROUND phase, with
associated AP/FD modes.
Note: If the thrust levers are not set briefly to TOGA detent, the FMS does not
engage the GO AROUND phase, and flying over, or close to the airport (less than 7
nm) will sequence the Destination waypoint in the F-PLN.

ROTATION.............................................................................................PERFORM
Initiate rotation towards 15 ° of pitch with all engines operative (approximately 12.5°
if one engine is out) to get a positive rate of climb then follow SRS Flight Director
pitch orders.
When near the ground, avoid excessive rotation rate in order to prevent a tail strike.

2.14.1 GO-AROUND AND MISSED APPROACH – ALL ENGINES OPERATING
The go-around decision starts with the “GO AROUND’’ callout from the Commander or the PF.
The go around procedure is executed by the PF. The duties of the pilots in case of a
Commander’s go around decision is as explained OM Part A. Decision of any pilot will not be
discussed and the go-around will be initiated immediately.

Call ‘’GO-AROUND, FLAPS 15, SET GO

Press TO/GA, and push the thrust
lever forward positively to ensure
G/A thrust is achieved.
If dual autopilot approach:
Check the aircraft rotates to Go Around
attitude,
read FMA and call ‘’GO-AROUND, TO GA’’
If single autopilot approach:
Rotate to GO-AROUND attitude, read the FMA.
Sets and checks the GO AROUND thrust and call
‘’GO AROUND THRUST SET’’
If the thrust approaching GA thrust, sets Flap 15

REJECTED LANDING
A rejected landing is defined as a go-around maneuver initiated below the minima.
Once the decision is made to reject the landing, the flight crew must be committed
to proceed with the go-around maneuver and not be tempted to retard the thrust
levers in a late decision to complete the landing.
TOGA thrust must be applied but a delayed flap retraction should be considered. If
the aircraft is on the runway when thrust is applied, a CONFIG warning will be
generated if the flaps are in CONF full.
The landing gear should be retracted when a positive climb is established with no
risk of further touch down. Climb out as for a standard go-around.
In any case, if reverse thrust has been applied, a full stop landing must be
completed.

AP/FD GO-AROUND PHASE ACTIVATION
The go-around phase is activated when the thrust levers are set to the TOGA
detent, the full forward thrust levers position, provided the flap lever is selected to
Flap 1 or greater. The FDs bars are displayed automatically and SRS and GA TRK
modes engage. The missed approach becomes the active F-PLN and the previously
flown approach is strung back into the F-PLN.
For the go-around, the appropriate flight reference is the attitude, because goaround is a dynamic maneuver. Therefore, if the "bird" is on, it is automatically
removed and the FD bars automatically replace the FPD.
If TOGA thrust is not required during a go-around for any reason, e.g. an early goaround ordered by ATC, it is essential that thrust levers are set momentarily but
without delay, to the TOGA detent, the full forward thrust levers position, in order
to ensure proper activation of the Go-Around phase (guidance modes and FMS
flight phase).
FCTM
If this is not done:
‐ The FMS remains in the Approach phase, and
‐ Since the Go-Around phase is not active, the FMS does not automatically restring the
approach procedure in the active F-PLN, and
‐ The active F-PLN is neither modified, nor erased, and
‐ When at the destination airfield, the FMS sequences the F-PLN and the aircraft flies
the Missed Approach procedure (the Missed Approach becomes green on the ND and
on the MCDU F-PLN page), and
‐ At the end of the Missed Approach procedure, when all the waypoints are sequenced,
the active F-PLN becomes "PPOS - DISCONT".

(G) If adequate visual references are not acquired when reaching DA(H)/MDA(H):
(1) Initiate a go-around climb
(2) Be sure correct go-around configuration set (flaps, landing gear)
(3) Avoid excessive control inputs, (high pitch low speed etc)
(4) Continue on the approach track until over the MAP (to guarantee obstacle
clearance during the go-around) and fly the published missed approach procedure.
No turn should be initiated before reaching the missed approach point and, if a
minimum altitude is indicated on the approach chart, until the indicated altitude
has been reached. (There is no restriction to fly over MAP at an altitude/height
greater than that published in the procedure)
