-trigger the go-around levers (set TOGA) and follow-through the A/THR operation;
-rotate (at the same rate as for a takeoff rotation, typically 3 degrees per second);
-follow the FD Pitch command (not exceeding the maximum pitch attitude applicable for the aircraft type, typically 18 degrees);
- check go-around Power ( thrust );
-check go-around Performance :
.. positive rate of climb;

.. speed at or above V APP;
.. speed brakes retracted;
.. radio-altimeter and barometric-altimeter indications increasing;
.. wings level, no roll rate;
.. gear up; and,
.. flaps as required.

-announce loudly the FMA, conditions permitting:
.. THR (thrust) mode, vertical and lateral modes engaged; and,
.. AP/FD status (i.e. AP engaged or hand flying with FD guidance);

.  
As thrust increases, be prepared to counteract the thrust nose up pitching effect (i.e. apply an increasing forward pressure – nose-down input -on the control column/side stick);

.  
Trim the aircraft nose down, as required (conventional aircraft models only);


.  Do not allow the pitch attitude to exceed an ultimate value (e.g. 25 degrees ), because a significant speed loss would occur;
If a high pitch attitude is inadvertently reached, an immediate and firm elevator nose down input (together with a nose down pitch trim order, on conventional aircraft models) must be applied to recover the target pitch attitude.

For the PNF :
.  When hearing the “ Go-around – Flaps “ call, without delay :
-retract one step of flaps, as applicable;
-check the FMA :
.. thrust, vertical and lateral modes engagement; and,
.. AP / FD engagement status;
-announce loudly the FMA, unless announced by PF:
.. THR (thrust) mode, vertical and lateral modes engaged; and,
.. AP/FD status (i.e. AP engaged or hand flying with FD guidance);
-announce “ Positive Climb “ and retract the landing gear, on PF command;
-monitor :
.. the airspeed and speed trend,
.. the pitch attitude and bank angle,
.. the thrust increase (confirm the thrust limit mode, as applicable, and the actual thrust on N1/EPR indicators ),

-continue monitoring the flight parameters and call any excessive parameter deviation :
.. “ speed “, if airspeed decreases below V APP – 5 kt;
.. “ speed trend “, if negative;
.. “ pitch “, if pitch attitude exceeds 20 degrees;
.. “ bank “, if bank angle exceeds 15 degrees ( 30 degrees if the missed-approach procedure requires a turn ); and/or,
.. “ thrust “, if a significant thrust loss is observed.

Summary of key points
For a safe go-around, strictly adhere to the following 3-Ps rule :
.  Pitch : 
-set and maintain the target pitch attitude; 
.  Power : 
-set and check go-around thrust; and, 
.  Performance : 
-check / confirm aircraft performance : 
.. positive rate of climb; 
.. speed at or above V APP; 
.. speed brakes retracted; 
.. radio-altimeter  and  barometric-altimeter 
indications increasing; 
.. wings level and no roll rate; 
.. gear up; and, 
.. flaps as required. 
.  
1.1 - Standard Operating Procedures,

 

Strict adherence to the defined PF / PNF task sharing and to crew resources management principles should be emphasized for;
