Introduction

Go-around: an essential safety manoeuvre for all pilots However, we have seen several examples where a safe go-around was

not achieved so we must review the go-around.

We regularly practiced in the simulator but often with engine failureand often from minima

By contrast, most real-world go-arounds are Light weight/High thrust/From any other point on the approach Pilots must be familiar and confident with all aspects of the

go-around manoeuvre

Why Go Around?

If :

The approach is not properly stabilized You have doubts about your situational awareness A malfunction occurs Adequate visual cues are not obtained at minima Any GPWS/TCAS or wind-shear alert occurs

THEN, APPLY THEGO-AROUND PROCEDURE!

Possible pilot reactionbased on illusion

Why is pitch so important?

During a manual go-around, if the requiredpitch is not reached or maintained

Linear acceleration will result, This may cause a, false climb illusion

Why is pitch so important?

May 2012FIS 2012

During a manual go-around, if the correct pitch attitude is notmaintained,

- The aircraft will accelerate towards the flap limit- There is NO speed protection when the A/THR is blue,

i.e. not active

Maintain the correct pitch attitudeNOTE : S PEED REFERENCE S YSTEM (SRS) pitch orders, when followed accurately, should

ensure that the aircraft remains at the correct speed during the go-around

Role of PNF/PM

May 2012FIS 2012

The PNF must make callouts if flight parameters deviate fromstandard / safe values.

- To enhance PFs awareness of the situation- To trigger a corrective action by the PF

Rapid ALT* engagement with autopilot

y

Rapid sequence of events with early capture of altitude (ALT*)

- Go-around initiated close to the selected FCU altitude- High rate of climb

As soon as ALT* engages:- The autopilot lowers the aircraft pitch and the aircraft accelerates

without any A/THR protections (A/THR blue)- LVR CLB flashes on FMA- THR LVRs must be set from TOGA to CL detent without delay to

activate the A/THR- This enables A/THR protections

- Providing flap overspeedprotection

Set THR LVRs from TOGA toCL detent without delay

Go-Around from Intermediate Approach

7/27/2019 4Go Around 2012


Go-Around Close to the Ground

When close to the ground,

- Initiate a Standard Go-Around- Avoid rapid rotation and excessive pitch- Low go-around may result in a runway contact, if it does, continue

with the standard go-around

Conclusion - recomendation

FD re-engagement at Go-Around is now basic on all aircraft sinceService Bulletin 22-1058.

This modification restores FD at go-around engagement (thrustlevers set to TOGA) regardless of the previous FD modes.

AIRBUS recommends all operators toimplement this Service Bulletin .

Conclusions

Go-around: an essential safety manoeuvre for all pilots

All pilots must be familiar and confident with the go-aroundmanoeuvre, from various initial conditions: Light weight and heavy Available thrust High energy Different configurations From intermediate, decision and low altitude

Familiarity and confidence will only come with practice

We must train for differentgo-arounds to train for safety

Conclusions

For a Safe Go-Around

Know the pitch target

Set the pitch and TOGA

Maintain the pitch (follow SRS)

Monitor the pitch and thrust

PNFPF

Call any deviations

Check the FMA Confirm the FMA

Know the pitch, set the pitch, keep the pitch!Pitch and thrust basic flying skills!
