From the A340 FCOM 2 :

LANDING RECOMMENDATIONS
For most cases of abnormal landing configuration the increased Actual Landing Distance does not exceed the Required Landing Distance in normal configuration. However, the addition of several of these factors can very quickly lead to an overrun. Special notice should be taken of the runway condition. A slippery runway is the most common reason for overrun at landing. The combination of a slippery runway with any other factor such as tailwind, or increase in approach speed, without reason, should be avoided. As far as possible, the combination of any failure affecting the braking capability of the aircraft (spoilers, reversers) with landing on a contaminated runway should either be avoided or carefully prepared, with a check of the available runway length against the forecasted landing distance. During a visual approach, all means of monitoring the flight path should be used : first of all use the ILS together with available visual aids such as VASI or PAPI. Approach speed must also be carefully monitored, along with the wind and ground speed in particular during final approach.


VLS: is 1.23 VS1g in config 3 or full. It is the same as VREF for config full in the QRH.

VAPP : When the tower wind has been inserted in the Landing Performance Page of the FMGS VAPP becomes VLS plus one third of the headwind component within the limits of VLS + 5 to +15 KTS.
When strong downbursts or windshear is expected up to VLS + 15 KTS.

FLUID CONTAMINATED RUNWAY LANDING PROCEDURES . . . . . . . . . . . . . . . . . . CONSIDER

— Avoid landing on contaminated runways if the antiskid is not functioning. Use manual braking and maximum reverse. However, although manual braking is recommended,there is no constraint preventing the selection of autobrake LOW or MED on approach to ensure early brake initiation.
— Approach at the normal speed.
— Make a positive touchdown after a brief flare.
— As soon as the aircraft has touched down, lower the nose wheel onto the runway and select maximum reverse thrust.
Do not hold the nose wheel off the ground.
— If necessary, the maximum reverse thrust can be used until the aircraft is fully stopped.
— If the runway length is limiting, apply the brakes before lowering the nose gear onto the runway, but be prepared to apply back stick to counter the nose down pitch produced by the brakes application. (The strength of this pitching moment will depend on the brake torque attainable on the slippery runway).
— Maintain directional control with the rudder as long as possible, use nose wheel steering with care.
