SEQ 025

The ECAM's VIB advisory (N1 ...- 6 units, N2 ...- 4.3 units) is mainly a guideline to induce the crew to monitor engine parameters more closely.
VIB detection alone does not require engine shutdown.

NOTE : 1. High engine vibrations may be accompanied by cockpit and cabin smoke, and/or

the smell of burning. This may be due only to compressor blade tip contact with associated abradable seals.
2. High N1 vibrations are generally accompanied by perceivable airframe
vibrations.
High N2 vibrations can occur without perceivable airframe vibrations.

 If no icing conditions :

- ENG PARAMETERS   CHECK
Check engine parameters and especially EGT ; crosscheck with the other engine. Report in the maintenance log.
• If rapid increase above the advisory :
- THRUST LEVER (affected engine)   RETARD
Flight conditions permitting, reduce N1 to maintain the vibration level below the advisory threshold.
Note : If the VIB indication does not decrease following thrust reduction, this may

indicate other engine problems. Apply the adequate procedure.
  If icing conditions :

An increase in N1 vibrations in icing conditions, with or without engine anti-ice, may be due to fan blades and/or spinner icing.
- A/THR   OFF
- ENGINE ANTI-ICE   CHECK
If ENG ANTI-ICE is off, switch it ON at idle fan speed, one engine after the other at an approximate 30-second interval.
- THRUST LEVER (one engine at a time) .. INCREASE THRUST
Increase thrust to a setting compatible with the flight phase. The VIB level will return to normal after ice is shed, despite a slight increase during acceleration.
Resume normal operation.
NOTE : When vibrations above the advisory level have been experienced during the flight, and

if possible, shut down the engine after landing, for taxiing.

SEQ 025
LDG CONF   DETERMINE
When an overweight landing has to be performed after an operational turnback, refer to the corresponding RTOW chart, or to FCOM to find the approach and landing configuration given as a function of the approach climb limiting weight.
NOTE: For weights greater than 70000 kg (or 154 000 lb), S speed is greater than VFE CONF 2 (200 knots). Consequently, on the FCU, the crew must select a speed below 200 knots before setting FLAPS 2. When in FLAPS 2, the crew can use managed speed again.
LDG DIST   CHECK
PACK 1 and 2   OFF or supplied by APU
Selecting packs OFF (or supplied from APU) will increase the maximum thrust available from the engines in the event of a go-around.
* In the final approach stages
* TARGET SPEED   VLS
Reduce the selected speed on the FCU to reach VLS at runway threshold.
Touch down as smoothly as possible (Maximum V/S at touchdown 360 ft/min).
* At main landing gear touchdown
* REVERSE THRUST   USE MAX AVAILABLE
* After nosewheel touchdown
* BRAKES   APPLY AS NECESSARY
Maximum braking may be used after nosewheel touchdown. But if landing distance permits, delay or reduce braking to fully benefit from the available runway length.
* Landing complete
* BRAKE FANS (‹   ON
Be prepared for tire deflation, if temperatures exceed 800° C.
