How will decide to approach with flap 2 or flap 3

FCTM is your friend :INTRODUCTION

The all engines failure is the situation where the aircraft entirely or partially loses engine thrust, and

is no longer able to maintain level flight.

The all engines failure can be identified by the Flight Warning Computer (FWC) or by the flight crew:

1. In most cases, the FWC detects an all engines failure condition and displays the ENG ALL

ENGINES FAILURE ECAM alert

2. In some cases, the FWC does not detect the all engines failure condition. In the case of partial

loss of thrust (no engine flame out) on one or more engines, the residual N2 may remain slightly

above the ENG 1(2) FAIL alert threshold.

Even if the ENG ALL ENGINES FAILURE alert is not triggered, the flight crew must rapidly decide

to apply either the ALL ENG FAIL QRH procedure, or the EMER LANDING QRH procedure,

depending on their assessment of the situation. If the flight crew considers there is sufficient time to

attempt an engine relight, they must apply the ALL ENG FAIL QRH procedure. However, if the flight

crew considers there is not sufficient time to attempt an engine relight, they must apply the EMER

LANDING QRH procedure. For more information, Refer to PR-AEP-MISC EMER LANDING.
