.  
Check target altitude and speed are as desired

.  
Select speedbrake (see note below)

NOTE : Speedbrakes should not be extended beyond the 1/2 position while speed is lower than .75 Mach and aircraft is above FL310. This is because prot is much lower at high level, which could lead to auto-retraction of the speedbrake. In addition to this limit, at high FLs the speedbrake should be extended slowly while monitoring VLS, so that angle of attack protection does not become active thereby causing speedbrake retraction. Use caution when using speedbrake if structural damage exists.

This section recaps the A320 RTOLW charts utilization and details the use for the new influence corrections (bleeds, QNH, wet runway) presentation.
Several examples summarizing the different possibilities of corrections use are solved step by step :
.
Example 1 : MTOW

.
Example 2 : MTOW on wet runway

.
Example 3 : MTOW - use of grad 1 and grad 2

.
Example 4 : Determination of flexible temperature

.
Example 5 : Contaminated runway

.
Example 6 : Determination of VAPP

.
Example 7 : Abnormal procedures

For a complete and thorough information about the RTOLW charts, refer to the FCOM Vol 2 -Chapter 2
02 - MTOW
