On slush or snow covered taxiways, delay flap selection until reaching the holding point to avoid contamination of the flap/slat actuation mechanism.
When holding on the ground in icing conditions for extended periods of time or if engine vibration is encountered, thrust should be increased periodically and just before take-off to shed any ice from the fan blades. Detailed information on this procedure can be found in FCOM 3.
TAXI WITH ENGINES SHUT DOWN
On A343 and A346 aircraft, taxi out for departure with one or two engines shut down may be operationally beneficial. FCOM 3.04.90 refers.
LINE-UP TECHNIQUE
It is important, particularly on limiting runways, not to sacrifice an excessive amount of runway length during the line-up, as a fixed distance is assumed for performance calculations relating to this manoeuvre.

THRUST SETTING
Following line up and after brake release, the PF announces "Set Thrust". The Captain then applies power in two stages:
.
From idle to (A333: 1.15 EPR), (A343: 50% N1), (A346: 1.05 EPR) in a rapid and continuous movement by reference to the TLA indicator on the EPR/N1 gauge. On the A333, there is protection between 1.16 -1.28 EPR to protect the engine from blade flutter. The FADEC will not allow fan speed acceleration above 1.16 EPR until the demanded EPR exceeds 1.28 EPR.
