1800TURN ON THE RUNWAY
Do not to attempt a 1800turn on a runway that is less than 56 m wide.
The following procedure is recommended for making a 1800turn:
For the Captain:
.
Taxi on the right hand side of the runway and turn left to establish a 200 divergence from the runway axis (using the ND or PFD) with a maximum ground speed of 10 kt.
.
When physically over the runway edge, smoothly initiate a full deflection turn to the right.
.
Asymmetric thrust should be used during the turn. Anticipation is required to ensure that asymmetric thrust is established before the turn is commenced, (50% N1 or 1.05 EPR), to maintain a continuous speed of approximately 5 to 8 kt throughout the manoeuvre.
.
Differential braking is not recommended due to gear assembly stress. Moreover, a braked pivot turn is NOT permitted (i.e. braking to fully stop the wheels on one main gear).
For the First Officer, the procedure is symmetrical (taxi on the left hand side of the runway).

LATE CHANGE OF RUNWAY AND/OR TAKE-OFF DATA
At airports where the opportunity for a late runway change could be expected, such as BKK, obtain ACARS RTOW for both runways prior to pushback. Provided performance is not limiting, input the same flap configuration for the secondary runway as that generated by the ACARS T/O data printout for the primary runway. Selection of the same flap configuration will reduce the chance of an incorrect configuration for takeoff.
Any modification to data shall be inserted and crosschecked following the same process defined in Normal Procedures. If take-off data has changed, or in the case of a runway change:
.
Obtain new ACARS RTOW. Again the Captain shall check the ACARS RTOW.
.
Modify the F-PLN to reflect the new ATC clearance for the runway, SID and transition.
.
Select appropriate navaids for the SID.
.
Insert the new PERF TO data; the MCDU may not clear the original PERF data when the runway is changed. Check PERF CLB data (speed PRESELECT requirement).
.
Confirm FLAPS LEVER set to new configuration.
.
Set revised V2 and Green Dot speed bugs on Standby ASI or ISIS.
.
Using the EFIS Control Panel, confirm selection of EFIS display for both ND mode and navaids.
.
Set first stop altitude on FCU. Preset FCU HDG bug if necessary.
.
Check transponder code is still correct.
TAKE-OFF BRIEFING CONFIRMATION
This briefing should normally be a brief confirmation of the thorough take-off briefing made at the parking bay. Any major changes that may have occurred should be reflected in a comprehensive re-briefing.

ADVERSE WEATHER
The major adverse weather factors affecting taxiing techniques are poor visibility and contaminated taxiways. In both instances, the taxi speed should be limited to 10 kt and any action which might divert the full attention of the crew from taxiing should be delayed until the aircraft is stopped. The Before Take-off checklist should be performed either before taxi or when reaching the holding point.
On a contaminated taxiway there are a number of additional factors that should be taken into account:
.
At speeds below 10 kt, the anti-skid is de-activated
.
Engine anti-ice increases ground idle thrust
.
Avoid large steering handwheel inputs to minimise the risk of skidding during turns
.
On slippery taxiways, it might be necessary to use differential braking and/or thrust to augment the nosewheel steering
