If, having reached the drift down ceiling altitude, obstacle problems remain, the drift down procedure must be maintained so as to fly an ascending cruise profile.
When clear of obstacles, set LRC ceiling on FCU, return to LRC speed and engage A/THR.
ENGINE-OUT LANDING
Applicable to: ALL
Autoland is available with one engine inoperative, and maximum use of the AP should be made to minimise crew workload. If required, a manual approach and landing with one engine inoperative is conventional. The pilot should trim to keep the slip indication centred. It remains yellow as long as the thrust on the remaining engine(s) is below a certain value.
With flap selected and above this threshold value, the indicator becomes the blue beta target. This is a visual cue that the aircraft is approaching its maximum thrust capability.
Do not select the gear down too early, as large amounts of power will be required to maintain level flight at high weights and/or high altitude airports.
To make the landing run easier, the rudder trim can be reset to zero in the later stages of the approach. On pressing the rudder trim reset button, the trim is removed and the pilot should anticipate the increased rudder force required. With rudder trim at zero, the neutral rudder pedal position corresponds to zero rudder and zero nose wheel deflection.
CIRCLING ONE ENGINE INOPERATIVE
Applicable to: ALL
In normal conditions, circling with one engine inoperative requires the down wind leg to be flown in CONF 3, with landing gear extended.
In hot and high conditions and at high landing weight, the aircraft may not be able to maintain level flight in CONF 3 with landing gear down. The flight crew should check the maximum weight showed in the QRH CIRCLING APPROACH WITH ONE ENGINE INOPERATIVE procedure table. If the landing weight is above this maximum value, the landing gear extension should be delayed until established on final approach.

FLIGHT CREW TRAINING MANUAL
If the approach is flown at less than 750 ft RA, the warning "L/G NOT DOWN" will be triggered. "TOO LOW GEAR" warning is to be expected, if the landing gear is not downlocked at 500 ft RA. Therefore, if weather conditions permit, it is recommended to fly a higher circling pattern.
ONE ENGINE INOPERATIVE GO-AROUND
Applicable to: ALL
A one engine inoperative go-around is similar to that flown with all engines. On the application of TOGA, rudder must be applied promptly to compensate for the increase in thrust and consequently to keep the beta target centred. Provided the flap lever is selected to Flap 1 or greater, SRS will engage
and will be followed. If SRS is not available, the initial target pitch attitude is 12.5 °. The lateral FD mode will be GA TRK and this must be considered with respect to terrain clearance. ALT should
be selected at the engine inoperative acceleration altitude, with the flap retraction and further climb carried out using the same technique as described earlier in "ENGINE FAILURE AFTER V1" section.
