.  
The display changes to IAS/MACH and the computed Mach are displayed in small font.

2. Aircraft is in climb phase and is in speed manual control
.  
The selected climb IAS has to be entered on the FCU if it has not been already preselected.

.  
The MCDU (PERF-CLIMB page) display is a IAS/MACH in accordance with the preselected IAS entry or with the FCU selection.

.  
The computed MACH is then displayed in small font.

.  
Guidance will use the selected IAS and the computed Mach thereafter.

3. Aircraft is in climb phase and in speed auto control
.  
The PRESEL field of PERF-CLIMB page is blank.

.  
The selected IAS has to be entered on the FCU and manual mode activated.

.  
The MCDU (PERF-CLIMB page) display is a IAS/MACH in accordance with the FCU selection.

.  
The computed MACH is then displayed in small font.

.  
Guidance will use the selected IAS and the computed Mach thereafter.

Note :
If during climb, a CRZ FL change modifies the climb IAS to introduce (as given by the tables), the new climb IAS has to be entered on the FCU as described in 2. above.
.  
The following tables are limited by the Max Altitude in ISA condition. However, the speeds provided are available for any temperature. In ISA deviation conditions, Cruise Altitude has to be limited by the FMGEC MAX Altitude.

.  
In order to perform minimum distance to climb, green dot should be selectedor an altitude constraint should be inserted on a waypoint in the FMS.
